Save Your Vision Month –

Save Your Vision Month is here.

We at DEF remind you to prioritize your eyes in 2024

In honor of Save Your Vision Month, here are some everyday things you can control to help “Save Your Vision”.

  • Enjoy a cup of tea –Green tea contains antioxidants, like vitamins C and E, lutein, and zeaxanthin that help protect against AMD and cataracts. It is it hydrating, helping you produce tears.
  • Take time to blink – On an average you blink about 15 – 20 times a minute. However, that rate drops by half when viewing text on a screen. Try using the 20/20/20 rule when staring at a screen: Every 20 minutes, look 20 feet away for 20 seconds so you can blink naturally and give your eyes time to relax.
  • Wear sunglasses and a hat – Exposure to ultraviolet (UV) rays can deteriorate vision over time and can lead to cataracts and possibly age-related macular degeneration (AMD). The American Optometric Association recommends sunglasses that block at least 99 percent of UVA and UVB radiation and that screen out 75 – 90% of visible light. And if you plan to spend a lot of time outdoors, it’s a good idea to get sunglasses with lenses that are polarized, which means that they’ve been treated to reduce glare. We suggest wearing a large brimmed hat to further protect your eyes.
  • Increase the seafood in your diet – Omega-3 fatty acids have been shown to bolster heart and brain health, as well as decrease your risk of eye disease. Studies show consuming omega-3 fatty acids, whether in foods you eat or in a supplement. It may help reduce your risk of developing macular degeneration. Research also shows not only can omega-3 fatty acids help reduce your risk of developing dry eyes, but it may also help treat bothersome symptoms as well.
  • Eat a rainbow – Eating a full rainbow of fruits and vegetables regularly helps give your body the nutrients it needs. In addition to fiber, vitamins and minerals, naturally colored foods contain what are known as phytochemicals, which are disease-fighting substances that also give fruits and vegetable their array of colors. Star nutrients are lutein and zeaxanthin—pigments found in such foods as dark, leafy greens, broccoli, zucchini, peas, and Brussels sprouts.  Also important are antioxidants found in red foods such as strawberries, cherries, red peppers and raspberries, orange foods have beta-carotene and include carrots, pumpkins, sweet potatoes and yams.
  • Use digital screens at a safe distance – The brightness and glare from computers, tablets, smartphones and televisions can lead to eyestrain after prolonged use. Recent studies have also shown ill-effects from the UV rays from these devices. Symptoms can include headaches, blurred vision, dry or red eyes and difficulty refocusing. Experts recommend keeping the computer screen at least an arm’s length away and that you hold a handheld device at least 16 inches from your eyes.
  • Contact lens solutions serve a purpose –The most harmful but common problem is moistening contacts with saliva instead of saline solution. Proper contact lens care is important for keeping and free from infection.
  • Make-up makeover – Replace tubes of mascara after three months, as it is a breeding ground for bacteria. Sharpen liner pencils regularly and while it is okay to line the base of your lashes, using the liner inside the lash line can block oil glands. Replace eye shadows yearly and don’t share your eye cosmetics.
  • Use protective goggles – According to studies nearly half of eye injuries happen at home. These injuries occur when protective eyewear is not used or when the incorrect protective eyewear is used and an exposure occurs from around or under the protective eye equipment.  Sports activities are another cause of eye injuries, from contact sports to sports that use balls that could catch you unaware.  When snowboarding or skiing remember to protect your eyes from the sun and wind with tinted goggles that have UV protection.
  • Have a yearly eye exam – Even if you don’t wear corrective lenses, adults should get a comprehensive eye exam (which includes dilating your pupils with drops) by age 40. After that a yearly eye exam is recommended to keep your eyes healthy and catch any changes in your eyes that may be indicators of eye disease. If you have a family history of glaucoma or age-related macular degeneration, or you have diabetes, you are at a higher risk for vision-related issues and your doctor may elect to see you more often. If you have symptoms such as persistent pain inside or behind your eyes, redness, or gradual loss of vision, make an appointment with your doctor immediately.

Blue Light: What Is It And How Does It Affect Your Eyes?

What Is Blue Light?

Blue light, also known as high-energy visible (HEV) light, is a color in the visible light spectrum that can be seen by human eyes. These wavelengths of visible and non-visible light are measured in nanometers (nm), and, in general, the shorter the wavelength, the higher the energy. Blue light is a short wavelength, which means it produces higher amounts of energy.

Unlike other forms of light, the eyes cannot effectively filter blue light, so more can pass through the eye to the retina. Blue light produces both benefits and concerns for our eyes and overall health.

Where Are You Exposed To Blue Light?

The largest source of blue light is sunlight. In addition, there are many other sources:

  • Fluorescent light
  • Fluorescent light bulbs
  • LED light
  • Flat screen LED televisions
  • Computer monitors, smart phones, and tablet screens

Blue light exposure you receive from screens is small compared to the amount of exposure from the sun. And yet, there is concern over the long-term effects of screen exposure because of the close proximity of the screens and the length of time spent looking at them. According to an NEI-funded study, children’s eyes absorb more blue light than adults from digital device screens.

Benefits of Blue Light?

Moderate amounts of blue light are essential for good health.

  • Promotes alertness
  • Boosts memory and cognitive function
  • Elevates mood
  • Regulates circadian rhythm

Blue Light and Digital Eyestrain

Using digital devices up close or for long periods can lead to digital eyestrain.

Research has shown that when people use computers, laptops, and other digital devices, they tend to blink less often than normal. Fewer blinks can mean less moisture.

Digital eyestrain means different things to different people, but is generally related to the focusing system of the eyes.

When your eyes are strained from staring at a blue-light-emitting screen, you might notice:

  • dry eyes
  • sore or irritated eyes
  • tired eyes
  • headaches
  • facial muscles fatigued by squinting

Blue light scatters more easily than most other visible light. This may make it difficult for your eye to focus when receiving blue light. Instead, your eye may digest blue light as poorly focused visual static. This reduction in contrast may make it more difficult for your eye to process blue light, potentially contributing to eyestrain.

Still, there isn’t enough evidence to confirm that blue light directly leads to eyestrain. More high-quality studies are needed.

How to Limit Blue Light Exposure

The American Academy of Ophthalmology (AAO) recommends that you take the steps below to reduce digital eyestrain.

1. Practice the 20/20/20 strategy

  • While you’re using a device that emits blue light, stop every 20 minutes to focus on objects that are around 20 feet away. Study those objects for 20 seconds before you return to your up-close viewing.
  • Keep your eyes moist
  • Eye drops, such as artificial tears, and room humidifiers are all good ways to keep your eyes from becoming too dry and irritated while you’re using blue-light-emitting devices.

2. Use eyeglasses with the right prescription

Squinting at screens for long periods isn’t recommended for the overall health of your eyes. If you wear prescription eyeglasses to correct your vision, make sure you’re wearing a prescription intended for the distance between your eyes and your screen — ideally an arm’s length away. Most glasses are formulated for longer distances.

3. Adjust the blue light on your screen

To lower the risk of eyestrain and sleep disturbance, you may want to set your screens to a “night shift” setting with warmer tones. You can also purchase blue-light-filtering screens to slip over your computer screen when you’re working at night. The filter could cut the glare of your screen.

And a 2020 research study shows that they block 30 to 60 percent of blue light, though it isn’t clear whether blocking the blue will help preserve the sleep-wake cycle for those who use backlit screens before bedtime.

June is Cataract Awareness Month

National Cataract Awareness Month is celebrated in June. The awareness campaign promotes information about the eye condition that is the leading cause of treatable vision loss in the U.S.  Yes, this is a scary fact, but no need to be frightened because cataracts are treatable with an outpatient surgery, which has over a 97% success rate.*

Vision loss from cataract is caused by clouding on the lens of the eye. Cataract surgery removes the cloudy lens and replaces it with a crystal-clear artificial lens.  This common eye condition mostly affects people over 50 and the causes can range from simple aging, diabetes, long-term eye diseases, and eye injury/inflammation, to factors like hereditary influences, smoking, intake of certain oral steroids, and so forth.

 

 

Cataract Vision Simulator

Although there may be no early symptoms, patients may begin to notice:

  • cloudy or blurry vision
  • colors that look faded
  • difficulty seeing at night
  • a halo around lights, making night driving difficult
  • seeing double out of the affected eye
  • frequent changes of the prescription of eyeglasses or contact lenses

 YOUR DIET IS VERY IMPORTANT

A healthy diet may help reduce risk of and/or delay formation and progression of cataracts. Research suggests that a diet high in vitamin C-rich foods — citrus (oranges, kiwi, lemon, grapefruit), bell peppers, strawberries, tomatoes, cruciferous vegetables (broccoli, Brussels sprouts, cabbage, cauliflower) — is helpful in slowing the progression of cataracts. More importantly, adopting good nutrition is a cornerstone of optimizing health early in life and can greatly reduce the risk of developing age-related diseases including cataracts.  For eye healthy recipes visit discoveryeye.org/eye-cook-delicious-food-health/

 

BE SURE TO HAVE AN ANNUAL EYE EXAM

By age 40, all adults should visit an eye specialist for a comprehensive eye exam to screen for early-stage cataracts and other eye diseases that are leading causes of low vision and even blindness. By age 65, a routine eye exam is recommended every year, in most cases to diagnose cataracts that are progressively clouding the lens. A comprehensive eye exam allows eye specialists to detect and monitor cataract progression as well as diagnosing other problems such as glaucoma. Patients should discuss with their eye specialist their vision problems and seek guidance about the timing of cataract surgery when worsening vision has compromised their quality of life and normal functioning.

 

LIVE A HEALTHY LIFESTYLE  

Multiple factors are at play that increase our risk for developing a degenerative eye disease or vision compromising conditions as we age.  If an individual lives long enough, then cataract formation is unavoidable. Living a healthy lifestyle, however, greatly improves an adult’s odds of avoiding early onset, faster progression, or possibly even avoiding the need for cataract surgery in the future.

 

WHY WE PROMOTE CATARACT AWARENESS MONTH 

  • It’s a celebration of sight – The ability to see the world clearly and in all its glory is something we shouldn’t take for granted. Millions upon millions of cells perform complex operations in our eyes to allow us the gift of sight. We should take care of our eyes and appreciate our glorious vision for what it is.
  • It’s a celebration of science – Science has not only explained to us how intricately our eyes work, but it has also revealed to us the many ways we can repair and treat them in case things go south. Medical advancements have ensured that about 80% of all eye diseases are treatable or can be prevented.
  • It’s a celebration of modern surgery – There’s “always” light at the end of the tunnel. Today’s cataract surgery is a modern day miracle developed by dedicated surgeons over the last five decades.  For most of us it is a painless, outpatient surgery with rapid return of excellent vision.

10 Tips for Summer Eye Care

Summer is almost here, whether you’re hanging out in the backyard pool, at the beach or spending quality time outdoors with family, it’s important to remember your eye safety — no matter how much fun you are having. 

Cornea burn, dry eye, tired eyes, pain and allergies are some of the common eye issues of the summer season. When people think of sunburns, the focus mostly is on skin but very few are aware of the fact that excessive heat and harmful UV rays can also lead to corneal burns, a condition where one gets blurry vision, dryness and a gritty feeling in the eye.

To help keep your eyes healthy, we’ve outlined 10 easy ways to protect them and still enjoy your time in the sun.

1. Sunglasses with Complete Ultraviolet Protection

As sunscreens are essential for skin, so are sun glasses for eyes. When you are stepping out in the peak summers, go for oversized shades as it will provide extra protection to your eyes. Shades protect the eyes from cornea burn from the damaging UV rays. Some of the major symptoms of cornea burn are dryness, discomfort and tearing up. Be sure to use sunglasses that filter out UV rays.

2. Avoid Sunburned Eyes

Sunburned eyes, also known as photokeratitis, is a painful eye condition that occurs when your eye is exposed to UV rays, either from the sun or from a man-made source.

This can happen when sunlight shines off the water, sand, snow, or other highly reflective surfaces into your eyes. These UV rays burn the surface of your eye and can cause pain, redness, blurriness, and even temporary vision loss. To prevent photokeratitis, wear 100% UV protection sunglasses when outdoors and appropriate eye protection when working with UV light.

3. Keep Your Eyes Moisturized

When you’re spending time outdoors, the heat and dry winds can irritate your eyes and can cause a condition called dry eye. The summer environment affects the tear film of the eye, drying out your eye’s surface.

Dry eye is a common condition but you’re at a higher risk of experiencing dry eye if you wear contact lenses or suffer from seasonal allergies. To protect your eyes in these conditions, use artificial tears to keep your eyes moist and refreshed.

4. Wash your hands frequently

This is one of the simplest and best ways to block all sorts of health disorders and infections around you. It protects the eyes and other parts of the body from bacterial and virus infections.

5. Follow Swimming Best Practices

Bodies of water such as lakes, rivers, and even swimming pools can be contaminated with bacteria and other microorganisms. This makes it very risky to wear contact lenses while swimming because the organisms can get underneath the contacts and cause an infection.

Goggles can reduce the contamination and irritation, but it’s still a best practice to splash your eyes with fresh water after getting out of the pool.

6. Wear Eye Protection While Working Outside

The summer months are a great time for home improvement and yard work, but this is when many accidents can happen with your eyes. Before beginning work in the yard or around the house, be sure to clear the area of any debris that could become airborne and injure your eye.

Simply wearing protective eyewear can reduce your risk for eye injury by 90%. Try to find wrap-around eyewear that protects the eyes from the sides as well. Most hardware stores carry excellent protective eyewear.

7. Keep Sunscreen Out of Your Eyes

During the summer, there’s a high chance you will get sunscreen or bug spray in your eyes. We’ve all had it happen to us and it’s very uncomfortable when it does. Next time, try to apply sunscreen very carefully and slowly around your face. Try to avoid your eyes and eyelids. Dermatologists recommend using mineral-based sunscreens because they stick to your skin and are less likely to run into your eyes.

If you do get sunscreen in your eyes, use fresh water to flush them out immediately.

8. Wear a hat

Hats aren’t just a fashion accessory, they are also a great way to protect your eyes from the glare of the sun! Add an extra layer of protection this summer by wearing a hat with a wide brim or a sun visor to keep your eyes comfortable.

9. Eat Healthy

Summer is an easier time to eat healthy fruits and vegetables. Tomatoes, zucchini, green peppers, melon, and peaches can be found just about anywhere and are great sources of healthy nutrients for your eyes. Omega-3 fatty acids benefit your eyes as well, so don’t forget to eat seeds and nuts.

In addition, always drink plenty of water during the summer. Dehydration even affects your eyes, which in turn can lead to blurry vision and blurred vision headaches.

10. Keep Up with Your Eye Appointments

It’s important to get regular eye exams every  year to keep your eyes healthy, so don’t skip out during the summer. Regular exams can help identify issues before they get worse.

 

DEF Helps Bring Vision-Saving Treatment To Patients With Retinitis Pigmentosa

Director of the Stem Cell and Retinal Regeneration Program at the  Gavin Herbert Eye Institute (GHEI), Henry Klassen, MD, Ph.D., leads life-changing research that will affect and influence vision-saving treatments for years to come.

Watch below to hear from Dr. Klassen on his recent stem cell research:

How to Keep Your Eyes Comfortable During Winter Months

Harsh weather conditions can reduce the natural moisture in your eyes and the irritation usually results in a burning or itching sensation that often leads to rubbing or scratching your eyes which can worsen the symptoms. Sometimes it feels like there is a foreign object in your eye and for some, dry eyes can even cause excessive tearing, as your eyes try to overcompensate for their lack of protective tears. Prolonged, untreated dry eyes can lead to blurred vision as well. Between the harsh winter winds outside and the dry heat radiating inside, our eyes are very quickly irritated and dried in the winter months.  The result is itchy, dry eyes that may cause pain, blurred vision, a burning sensation, or even watery vision as our eyes try to compensate for the dryness.

What Are The Symptoms?

  • Uncomfortable, stingy, burning or scratchy feeling.
  • Stringy mucus in or around your eyes
  • Increased eye irritation from smoke or wind
  • Eye fatigue
  • Sensitivity to light
  • Eye redness
  • A sensation of having something in your eyes
  • Difficulty wearing contact lenses
  • Periods of excessive tearing
  • Blurred vision, often worsening at the end of the day or after focusing for a prolonged period

10 TIPS TO KEEP YOUR EYES COMFORTABLE DURING THE WINTER MONTHS

Whatever the symptoms, dry eyes can cause significant discomfort during the long winters and relief can seriously improve your quality of life.

  1. To keep eyes moist, apply artificial tears/eye drops a few times a day. If you have chronic dry eyes, speak to your eye doctor about the best product for your condition.
  2. Drink a lot of fluids – keeping your body hydrated will also help maintain the moisture in your eyes.
  3. If you spend a lot of time indoors in heated environments, use a humidifier to add some moisture back into the air.
  4. Try to situate yourself away from sources of heat, especially if they are blowing. While a nice cozy fire can add to the perfect winter evening, make sure to keep your distance so dry eyes don’t ruin it. 
  5. Staring at a computer or digital device for extended amounts of time can further dry out your eyes. If you spend a lot of time staring at the screen, make sure you blink often and practice the 20/20/20 rule – every 20 minutes, look 20 feet away for 20 seconds. Use artificial tears often to lubricate eyes during long periods of using your eyes.
  6. Avoid air blowing in your eyes. Don’t direct hair dryers, car heaters, air conditioners or fans toward your eyes. In your car, direct heat to floor vents and away from your eyes once your windshield is defrosted.
  7. Stop smoking and avoid smoky environments.
  8. Don’t rub your eyes! This will only increase irritation and can also lead to infections if your hands are not clean.
  9. Give your eyes a break and break out your glasses. If your contact lenses are causing further irritation, take a break and wear your glasses for a few hours or days. Also talk to your optometrist about switching to contacts that are better for dry eyes.
  10. Protect your eyes. If you know you are going to be venturing into harsh weather conditions, such as extreme cold or wind, make sure you wear protection. Try large, 100% UV protective eyeglasses and a hat with a visor to keep the wind and particles from getting near your eyes. If you are a winter sports enthusiast, make sure you wear well-fitted ski goggles.

If you find that after following these tips you continue to suffer, contact your eye doctor.

A Thanksgiving Spread that Promotes Eye Health

Thanksgiving is almost here; a meal that nourishes the family bonds and traditions.  It’s the one time of the year where you can guarantee your eyes will be bigger than your stomach. This meal also has another added bonus — almost every item on the Thanksgiving table is healthy for your eyesight!

Here are several of the most popular Thanksgiving dishes and their corresponding benefits to your eye health:

Turkey –

No Thanksgiving is complete without a turkey, roasted golden brown and stuffed with fresh vegetables and herbs. Turkey is loaded with zinc and B-vitamin niacin, which helps prevent the formation of cataracts. Cataracts are the leading cause of vision loss in the United States, so gobble up!  You are “preventing” cataracts with every bite.

 

Spinach, Green Bean Casserole, Asparagus and Brussel Sprouts –

These foods and other leafy greens are loaded with lutein and zeaxanthin, two nutrients that protect the retina, which may also help reduce the risk of cataracts and macular degeneration.  Healthy Green Bean Casserole Recipe

 

Sweet Potatoes –

Sweet potatoes are full of Beta-carotene, which is a carotenoid and antioxidant that promotes night vision and overall good eyesight. Sweet potatoes are also loaded with vitamins C and E. Diets that are rich in these vitamins can help prevent or delay the development of cataracts and macular degeneration. Mashed Sweet Potatoes Recipe

 

Cranberry Sauce –

Cranberries contain bioflavonoids, a large class of antioxidants. Bioflavonoids are found in the pulp, skin and rinds of foods that contain vitamin C. Both flavonoids and vitamin C help protect the eyes from free radical damage caused by pollution and the body’s normal metabolic processes.

 

Pumpkin Pie –

Pumpkin is one of the best sources of vitamin A, so pumpkin pie is an eye-healthy dessert. In fact, one cup of cooked, mashed pumpkin contains more than 200 percent of the recommended daily intake of Vitamin A. Vitamin A provides nourishment and protection to the eye’s lens, cornea and macula (part of the retina), so it improves night vision. 

 

A diet that’s full of the right nutrients is a great start to keeping your eyes healthy, but don’t forget that regular eye exams are equally important! We hope you enjoy a happy and delicious Thanksgiving with family and friends.

5 Most Common Eye Problems

Most people have eye problems at one time or another. Some are minor and will go away on their own, or are easy to treat at home. Others need a specialist’s care. Some eye issues come with age while others may be a serious condition.

 

If you’ve never had a problem with your eyes it can be easy to forget how important it is to take care of them. The good news is that it’s never too late to start taking care of your eye health. Regular eye health appointments and eye exams can lead to early diagnosis. This is key to correcting or slowing most eye conditions.  Always see your eye care professional if your vision problem lasts for more than a few days or worsens.

The five most common eye conditions leading to loss of vision or blindness are:

  • Dry Eye
  • Cataracts
  • Diabetic retinopathy
  • Glaucoma
  • Age-related macular degeneration

Dry Eye

Dry eye is a common condition that occurs when your tears aren’t able to provide adequate lubrication for your eyes. Tears can be inadequate for many reasons. For example, dry eyes may occur if you don’t produce enough tears or if you produce poor-quality tears. Dry eyes can also feel very uncomfortable.

Signs and symptoms, which usually affect both eyes, may include:

  • A stinging, burning or scratchy sensation in your eyes
  • Stringy mucus in or around your eyes
  • Sensitivity to light
  • Eye redness
  • A sensation of having something in your eyes
  • Difficulty wearing contact lenses
  • Difficulty with nighttime driving
  • Watery eyes, which is the body’s response to the irritation of dry eyes
  • Blurred vision or eye fatigue

Cataracts

A cataract is a clouding of the lens in the eye that typically will affect your vision. Most cataracts are related to aging. People who have cataracts often have other vision problems in one or both eyes that accompany the cataract, such as nearsightedness (myopia), farsightedness (hyperopia), astigmatism (blurred vision), and/or presbyopia (reading problems).

The lens lies behind the iris and the pupil. It works much like a camera lens. It focuses light onto the retina at the back of the eye, where an image is recorded and sent to the brain. The lens also adjusts the eye’s focus, letting us see things clearly both up close and far away. The lens is made of mostly water and protein. The protein is arranged in a precise way that normally keeps the lens clear and lets light pass through it.

But as we age, some of the protein may clump together and start to cloud the lens. This is a cataract. Over time, the cataract may grow larger or more dense making it harder to see. There are no known medications or diets to prevent age-related cataract so currently the only treatment is cataract surgery. Consult an ophthalmologist for a cataract surgery evaluation.

Diabetic Retinopathy

Diabetic retinopathy is the most common diabetic eye disease and a leading cause of blindness in American adults caused by changes in the blood vessels of the retina.

We know that:

  • Currently more than 4 million Americans aged 40 and older have some form of diabetic retinopathy
  • There is a higher prevalence in African Americans, Hispanics/Latinos, American Indians, and Alaska Natives aged 20 and older
  • Preventive measures help and it is highly treatable.

In some people with diabetic retinopathy, blood vessels may swell and leak fluid or blood inside the eye. In other people, abnormal new blood vessels grow on the surface of the retina. The retina is the light-sensitive tissue at the back of the eye. A healthy retina is necessary for good vision.

Two important tips for diabetic retinopathy prevention: 1) Diabetic retinopathy is worse in patients with poor blood sugar control, so follow your diet and medication prescriptions carefully. 2) Get a dilated eye exam from your ophthalmologist every year for early diagnosis and treatment.

Glaucoma

Glaucoma is a disease that causes damage to the major nerve of the eye called the optic nerve, a part of the central nervous system that carries visual information from the eye to the brain.

The eye experiences a gradual increase of intraocular pressure (IOP) due to an imbalance of the fluid produced in the eye and the amount of fluid drained. Over time, elevated IOP can cause vision loss. The most common form of glaucoma is primary open angle glaucoma which affects about 3 million Americans. However, there are other types including narrow angle, congenital, normal tension, and secondary glaucoma.

At age 50 about 2% of the US population has glaucoma, increasing to 4% by age 70 and 10% for those over age 80. While anyone can develop glaucoma, there are some risk factors that increase the likelihood of having this disease, which include:

  • A family history of glaucoma
  • Mexican American heritage over the age of 60
  • African American heritage over age 40.

Often people with glaucoma are unaware they have the disease because there are no symptoms, so it is recommended that you have a dilated eye exam every two years. With early diagnosis there are treatments that can often protect against irreversible damage to the optic nerve that can lead to serious vision loss. Glaucoma can be treated with eye medications, lasers, and various surgical procedures. However, if glaucoma is not controlled can cause debilitating loss of vision.

Age-Related Macular Degeneration

Age-Related Macular degeneration (AMD) is a progressive eye condition affecting as many as 15 million Americans. The disease attacks the macula of the eye, where our sharpest central vision occurs, affecting reading, driving, identifying faces, watching television, safely navigating stairs and performing other daily tasks. Although it rarely results in complete blindness, it robs the individual of all but the outermost, peripheral vision, leaving only dim images or black holes at the center of vision.

As the disease progresses color vision and central vision sharpness deteriorates. the gradual destruction of light sensitive cells continues until large areas are totally gone. Peripheral vision remains, but the ability to clearly see straight ahead and to see color is lost.

For many people, the first sign of macular degeneration is something they notice themselves. Straight lines like doorways or telephone wires may appear wavy or disconnected. When you look at a person, their face may be blurred while the rest of them is in focus. Lines of print may be blurred in the center or the lines may be crooked. For some people, there is a sudden blurring or loss of sight in the center of vision. For any sudden change in vision, you should contact your ophthalmologist immediately.

AMD can be classified into Early AMD and Late AMD. In Early AMD, a patient may have drusen, which are small protein/lipid deposits underneath the retina, and they can still have good vision. In Late AMD, there are two common forms that occur—wet (neovascular AMD) and dry (atrophic AMD). The wet AMD has abnormal blood vessels beneath the retina that leak blood which can greatly distort the vision and cause a central blind spot.  Approximately 10-15% of patients have the wet form. Fortunately, there are treatments for wet AMD.   To date, the dry, atrophic form of AMD does not have any treatments available. In dry AMD, the retinal pigment epithelial (RPE) cells, which are the posterior-most layer of cells in the retina, undergo extensive degeneration that causes the overlying retina to lose function.  We do not know what causes the RPE cells to become unhealthy and start to die.  Many research laboratories worldwide are studying the causes of dry AMD and how to treat it.

Help keep your eyes healthy for years to come with regular eye exams, and treatment at the first sign of a problem.

 

Spring Allergies and Your Eyes

As winter shifts to spring, and flowers, grasses and trees begin to bloom, spring can take a toll on your eyes if you suffer from seasonal allergies. The spring season has a marked an increase in pollen and allergens in the air, that leave you with congestion, headaches, and itchy, swollen eyes, known as eye allergies.

According to the American Academy of Ophthalmology, eye allergies are also called allergic conjunctivitis, and are pretty common. They occur when the eyes react to something that irritates them (called an allergen). The eyes produce a substance called histamine to fight off the allergen. As a result, the eyelids and conjunctiva become red, swollen, and itchy. The eyes can tear and burn. Unlike other kinds of conjunctivitis, eye allergies do not spread from person to person.

What Are the Symptoms of Eye Allergies?

The most common eye allergy symptoms include:

  • red, swollen, or itchy eyes
  • burning or tearing of the eyes
  • sensitivity to light

What are Eye Allergy Triggers?

  • Outdoor allergens, such as pollen from grass, trees, and ragweed
  • Indoor allergens, such as dust mites, pet dander, and mold
  • Irritants, such as cigarette smoke, perfume

Spring Allergy Management

To combat seasonal eye allergies, you must have a dual focus on both prevention and treatment for symptoms.  By making some minor changes to your environment and activities, you can significantly reduce the amount of allergens you come in contact with, and lessen the symptoms you’re experiencing.  Use these seven methods to soothe your eye irritations related to allergies.

  1. Avoid Allergens

The best strategy to minimize your eye discomfort during the spring is to limit your exposure to allergens. As winter comes to an end, create an actionable plan that helps you avoid seasonal allergens like pollen.

Steps you take may include:

    • Changing your HVAC filters before turning on your cooling system for the first time
    • Purchase and use an in-house air purifier
    • Checking pollen levels online as part of your daily routine
    • Cleaning your home more frequently
    • Keeping your windows closed
    • Spring cleaning before the weather actually warms up

These preventative measures are an important first step to good eye health during allergy season.

 

  1. Don’t Wear Contacts

If you are prone to allergy-related eye irritation, stop wearing your contacts for the first month or so of spring weather. While contacts do not cause allergy symptoms, they can aggravate any symptoms that do appear.

You may want to schedule an eye exam, to prepare for switching to full-time glasses use.  This exam presents a good opportunity for you to check that your glasses prescription is current and to make any necessary updates to maintain your comfort and vision quality.

 

  1. Rinse with Sterile Non-Preserved Saline

Eye allergies can cause changes in tear production. Many individuals experience eye dryness or excess tears due to allergies. In some cases, your eyes may water frequently but still feel dry due to allergens.

Much of this type of irritation occurs when airborne allergens come into contact with the surface of the eyeball. To minimize your allergen exposure, rinse your eyes with saline solution. This may reduce the urge to rub your eyes, which is important because rubbing can trigger a release of more histamines and cause redness, swelling, and blood vessel breakage.

 

  1.  Use Non-Preserved Artificial Tear Drops or Medicated Eye Drops

You may also want to use non-preserved artificial tears to help maintain correct eye lubrication. Before you begin a new eye health regimen, consult with your optometrist to determine which brand and formula is best for your symptoms.

In addition to sterile rinses or lubricant eye drops, using medicated eye drops may help relieve some of the discomfort associated with seasonal eye allergies. Decongestant or antihistamine drops can control redness, itchiness, and other symptoms.

 

  1. Try Cold Therapy

Many individuals notice redness, tenderness, and swelling in the eye area when suffering from allergies. Applying cool or cold compresses can provide immediate soothing relief for these symptoms, including improving the appearance of the skin around the eyes.

Use a clean soft cloth or compress designed for use in the eye area. These compresses are gentler than traditional cold therapy tools and are safer for your eyes. Soak the compress in cool water, wring it out, and place over the eyes. You can refresh the compress with water when the cloth no longer feels cold.  To address more intense symptoms, wet your compress, wring out the cloth, and put it in the refrigerator for 10 to 15 minutes. This colder compress will last longer and provide relief for more advanced symptoms.

 

  1. Wash Your Hands and Face Frequently

As mentioned above, many eye allergy symptoms come from allergens landing on the eye. In addition to floating airborne allergens, your eyes could also suffer from contact with allergens that are transferred in on your skin or hair.

Wash your hands more frequently during allergy season. You should also wash your face twice a day and rinse the area around your eyes as needed. These steps reduce the concentration of allergens on your skin. You may also want to pin back any hair that may cover your face at eye height to minimize your allergen exposure.

 

  1. Wear Sunglasses

When you do need to be outside, wear glasses to protect the surface of your eyes from direct contact with allergens. You may prefer to wear sunglasses rather than your usual glasses because most sunglasses have larger lenses than everyday eyeglasses and, therefore, provide more protection.

If you need constant vision correction, but want the benefits of wearing sunglasses, talk to your eye doctor about investing in a pair of high-quality prescription sunglasses.

 

  1. Consult Your Eye Care Professional

If your symptoms continue, consult your eye care professional for help with diagnosis and treatment. There are many prescription medications, not available over the counter, to help control severe allergic symptoms.

 

If your allergies cause vision changes, feelings of a foreign object in your eye, or acute pain, make an appointment as soon as possible.
