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 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.

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.

September is Healthy Aging Month

Healthy Aging Month is an annual health observance designed to focus national attention on the positive aspects of growing older. Aging is a process that brings many changes. Vision loss and blindness, however, do not have to be one of them. There are several simple steps you can take to help keep your eyes healthy for the rest of your life.

Eye diseases often have no early symptoms, but can be detected during a comprehensive dilated eye exam. A comprehensive dilated eye exam is different from the basic eye exam or screening you have for glasses or contacts. By dilating the pupils and examining the back of the eyes, your eye care professional can detect eye diseases in their early stages, before vision loss occurs. By performing a comprehensive eye exam, your eye care professional can check for early signs of –

Here are some other tips to maintain healthy vision now and as you age:

Eat a healthy, balanced diet. Fruits and vegetables can help keep your eyes healthy. Visit our website for healthy eye recipes, click here Eye Cook.

Maintain a healthy weight. Being overweight increases your risk for diabetes. By exercising regularly, you can help keep your body healthy and prevent vision loss.

Don’t smoke. Smoking increases your risk for age-related macular degeneration, cataract, and other eye diseases and conditions that can damage the optic nerve.

Wear protective eyewear when outdoors. Protecting your eyes from the sun’s ultraviolet rays when you are outdoors is vital for your eye health. Wearing sunglasses that block 99 to 100 percent of both UV-A and UV-B radiation.

Know your family history. Talk to your family members about their eye health history. It’s important to know if anyone has been diagnosed with a disease or condition since many are hereditary, such as glaucoma, macular degeneration, and diabetes . This will help determine if you are at higher risk for developing an eye disease or condition.

Consider a multivitamin. Vitamins C, E and the mineral zinc have been shown to promote eye health. Vitamins with Lutein and Zeaxanthin have been known to help patients with moderate to severe age-related macular degeneration.

Give your eyes a rest. If you spend a lot of time at the computer or focusing at any one distance, you sometimes forget to blink, resulting in dryness and eye fatigue. Every 20 minutes, look away about 20 feet in front of you for 20 seconds. This can help reduce eyestrain. Consider using a lubricant eye drop during long periods of intense eye use and rest your eyes for 5 minutes.

You can’t stop time, but you can take care of your eyes so that they remain healthy as you age. Having a healthy vision can be possible at any age! Even if you are not experiencing vision problems, visiting an eye care professional regularly for a comprehensive dilated eye exam is the most important thing you can do to reduce your risk of vision loss as you age.

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.

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.

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.

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.
Drink a lot of fluids – keeping your body hydrated will also help maintain the moisture in your eyes.
If you spend a lot of time indoors in heated environments, use a humidifier to add some moisture back into the air.
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.
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.
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.
Stop smoking and avoid smoky environments.
Don’t rub your eyes! This will only increase irritation and can also lead to infections if your hands are not clean.
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.
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.
