Thanksgiving Dinner for Your EYES!

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 is one of 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.

UNDERSTANDING YOUR EYE PRESCRIPTION

If you need eyeglasses, it is because you were diagnosed with a refractive error during your eye exam. This means your eyes have trouble focusing and images can appear blurry. Types of refractive errors include being near-sighted (myopia), far-sighted (presbyopia) or having an astigmatism (your cornea is an irregular shape).

Understanding Your Eyeglass PrescriptionUnderstanding What 20/20 Vision Means

The number is based on you standing a distance of 20 feet in front of a standard eye chart to test your visual acuity. If during an eye test you can read the big E at the top of the eye chart, but none of the letters below that, your vision is considered 20/200. That means you can read a letter at 20 feet that people with “normal” vision can read at 200 feet, meaning you have very poor distance visual acuity. If you can read the seventh line from the top of most charts, your vision is 20/20. Any line below that would be 20/15 or below and indicates that you have exceptional visual acuity. Each eye is tested separately.

Understanding Your Eyeglass Prescription

The prescription you receive may be a form with headings that are filled in, or it may just be written out. In any case, it is written in a specific order, with the results for each eye listed separately.

OD is an abbreviation for oculus dexter, meaning right eye, while OS is oculus sinister, meaning left eye. If both eyes are being referred to the abbreviation you will see is OU (oculus uterque) meaning both eyes.

The next term on your prescription is Sphere (SPH) and is are measured in diopters (D). This number tells you how strong your lenses need to be to correct your vision. If this number has a minus sign (–), you are nearsighted; if the number has a plus sign (+) or is not preceded by any sign, you are farsighted.

Next may be cylinder (CYL), an indicator of the lens power if you have an astigmatism. The number for the CYL has the same format as the SPH, a minus sign (for the correction of nearsighted astigmatism) or a plus sign (for the correction of farsighted astigmatism). If there is no number given you either have no astigmatism, or your astigmatism is so slight that it is not really necessary to correct it.

If you do have a CYL number you will also have an axis number, based on a protractor scale that tells you where on the eye the astigmatism is found. For example, 

SPH –2.50   CYL +5.00 Axis 40 means you have a nearsightedness of -2.50 diopters with an astigmatism of +5.00 along the 40 degree axis.

If you are getting bifocals or progressive lenses, there is another number called an “Add.” This number is the amount of additional correction your eyes need to focus at close distance and will always be a positive number, whether or not the + sign is there.

Needless to say, eyeglasses can be expensive, but understanding a prescription should help you understand why. The stronger the lens the more expensive it is and then with each adjustment, the cost also increases.  Also, don’t forget that anti-glare or UV protective coatings add to the costs, but most people feel it is well worth it. Eye glasses are an investment in your safety, job, independence and letting you enjoy leisure-time activities you enjoy.

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.

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:

February is AMD/Low Vision Awareness Month

Age-Related Macular Degeneration (AMD) Awareness Month is observed annually every February. It’s an awareness month targeted at spreading information about AMD and other sight threatening diseases that could lead to visual impairment.

AMD is a disease that is a leading cause of low vision in Americans older than 50 years of age. The macula is the part of the eye affected by this disease, a pigmented, oval-shaped part of the retina. About 5mm in diameter, it is responsible for the central vision required for driving, reading, and fine detail. AMD, is a progressive disease that causes retinal cells to slowly die, though it causes no physical pain.

Medical experts have been able to identify some risk factors that might lead to the onset of AMD, including high blood pressure, high levels of blood cholesterol, obesity, and smoking. Other risk factors that a person has no control over are age, heredity, race, and gender. Symptoms of the disease include blurry vision, blind spots, straight lines appearing wavy, doorways seeming crooked, and objects appearing farther away or smaller. When any of these symptoms present themselves, the concerned individual is advised to immediately visit an ophthalmologist.

January is Glaucoma Awareness Month

January is Glaucoma Awareness Month and the perfect time to raise awareness about this disease. Early on there are no symptoms.  In fact, many people with glaucoma don’t even know they have it. Learn about glaucoma and the steps you can take to reduce your risk of vision loss.

There are several types of glaucoma, although the most common type of glaucoma is age-related Primary Open-Angle Glaucoma.  It affects people starting at age 40, but can develop anytime later in life.

So, the way to detect if you have it is to get regular thorough eye examinations every two years after age 40.

ARE YOU AT RISK?

Anyone can get glaucoma, but certain groups are at higher risk. These groups include African Americans and Hispanics over the age of 40, and all people over the age of 60. Since it is hereditary, people with a family history of glaucoma and people who have diabetes are at higher risk.

4 GLAUCOMA GUIDELINES TO REMEMBER

1. Glaucoma can affect people of all ages – Although it is generally associated with seniors, glaucoma can strike anyone.

2. Demographics do play a role – Glaucoma is a leading cause of blindness among African Americans; it’s also highly prevalent in Hispanics over the age 65.

3. Is glaucoma hereditary? – The risk of developing primary open–angle glaucoma is up to nine times more likely if parents or siblings have the disease.

4. Hope for future glaucoma patients – Although there is no cure for glaucoma, early diagnosis and treatment can help control the disease and slow or stop the process of vision loss and blindness.

There are many steps you can take to help protect your eyes and lower your risk of vision loss from glaucoma. 

  • If you are in a high-risk group, get a comprehensive dilated eye exam every two years to catch glaucoma early and start treatment. Prescription eye drops, and if that fails, surgery can stop glaucoma from progressing.
  • Even if you are not in a high-risk group, getting a comprehensive dilated eye exams can help catch glaucoma and other eye diseases early.
  • Open-angle glaucoma does not have symptoms and is hereditary. So talk to your family members about their vision health to help protect your eyes and theirs.
  • Maintaining a healthy weight, controlling your blood pressure, being physically active and avoiding smoking will help you avoid vision loss from glaucoma.
  • Stay aware of the risks and symptoms and remember an annual comprehensive eye exam is key for early detection of glaucoma and other eye diseases.

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.

BACK-TO-SCHOOL EYE CARE FOR KIDS: WHAT YOU NEED TO KNOW

View Video
It’s back-to-school time! As your child prepares to start another school year, don’t forget to take care of one of their most important learning tools — their eyes.  Find out how you can help keep their eyes healthy, and why an eye exam is so important.

Be aware of vision problems:

Your kid may be spending more time in front of the screen than usual — and that could put him or her at increased risk for certain vision problems or eye conditions.

  • Nearsightedness: If your child is not already nearsighted, doing a lot of “close work” (using a screen or even in a book) can increase their likelihood of developing this condition. Encourage them to hold books or screens at least 18 inches away.
  • Dry Eye Syndrome: When we stare at a screen all day, our blink rate decreases significantly. The blinking action secretes an oil called meibum (one of the three layers of tear film), which keeps our eyes moist. When we don’t blink as much, our eyes can become overly dry and irritated.
  • Eye Strain and Fatigue: Excessive screen time can also lead to strain, fatigue, blurry vision, itchy eyes, and headaches.

Watch for behavioral changes that may signal vision trouble, for example:

  • Talk to your child about their new classroom or where they’re sitting to gauge whether they’re having issues seeing.
  • Ask them whether their eyes ever feel tired after watching something on a screen.
  • Watch for blinking, squinting and tearing of their eyes.
  • Pay attention to headaches or fatigue.

Help minimize any risk to your child’s eyes by doing the following:

  • Make sure they take frequent screen breaks. Instead of focusing directly on the screen, encourage your child to look around the room every now and then, or take some time to stare out the window (at least 20 seconds is recommended by the American Optometric Association). You can even remind them to blink.
  • Position the monitor or screen so it’s about 25 inches away, and also position it so their gaze is slightly downward.
  • Adjust the room lighting so that the screen isn’t brighter than the surrounding light. If it is, your child’s eyes will have to work harder.
  • Sharpen your child’s vision skills with “traditional” non-screen-based activities, like puzzles, blocks, drawing and painting, and playing catch.

Don’t Forget the Eye Exam

It’s easy for us to forget about our eyes let alone our child’s, but it is very important to get your child’s eyes checked regularly.

It is absolutely critical to ensure healthy eye development and that they have the visual skills necessary for successful learning. No matter where your child will be participating in school this year — don’t skip the trip to the eye doctor.

The American Optometric Association recommends children have an eye exam by the time they reach one year old, at least once between 3 and 5 years old, and once a year after first grade until they graduate. Your eye doctor can recommend the best frequency for your child.

Your child should still receive a comprehensive eye exam, whether or not they have received a vision screening at school or even at their pediatrician’s office.  While vision screenings can indicate some vision trouble, they often only test your child’s ability to see things that are far away, such as a classroom whiteboard.  Also, keep in mind the school screeners usually do not have all the necessary equipment or training to detect many eye health problems in children.

A comprehensive eye examination looks at complete eye health, and includes tests for the following, in addition to an understanding of patient and family health history:

  • Visual acuity
  • Depth perception
  • Color vision
  • Peripheral vision
  • Refractive errors (like nearsightedness, farsightedness and astigmatism)
  • Eye focusing, tracking, teaming and other eye movement abilities

Specialists state that 80% of what your children learn in school is taught visually. Untreated vision troubles can put children at a substantial disadvantage. Be certain to arrange that your child has a complete eye exam before school starts.
