Common Eye Conditions to Watch Out For

  • Regular Eye Exams: Scheduling regular comprehensive eye exams is key to maintaining good vision and overall eye health. Eye doctors can detect vision issues like nearsightedness or farsightedness and prescribe glasses or contacts to correct them. More serious issues like glaucoma, diabetic retinopathy, and age-related macular degeneration can often be caught early through eye exams before causing permanent vision loss. As a general rule of thumb, most people should get a comprehensive eye exam once every 1-2 years, or more frequently if recommended by an eye doctor.
  • Managing Common Eye Conditions: Some of the most common eye conditions like dry eyes, eyestrain, and floaters can often be managed with lifestyle changes and over-the-counter treatments. Using a warm washcloth as a compress, limiting screen time, using proper lighting, and using lubricating eye drops can help relieve dry, tired eyes. Floaters, the spots or cobweb-like shapes that appear in your field of vision, are usually harmless and often fade over time. See an eye doctor right away if you notice any sudden vision changes, loss of vision, or new floaters.
  • The Role of Nutrition: Eating a healthy diet with plenty of fruits and vegetables, especially leafy greens like spinach and kale which are high in lutein and zeaxanthin, is important for eye health and possibly helping prevent age-related vision decline. Omega-3 fatty acids found in fish, nuts, and seeds are also beneficial for eye health. Limiting sugar intake can help reduce the risk of diabetes and diabetic retinopathy. Staying at a healthy weight and not smoking are other ways to support eye health through lifestyle choices.
  • Protecting Your Eyes at Work: If you spend long hours looking at computer, tablet, or phone screens, it’s important to take regular breaks to reduce eye strain. Use the 20-20-20 rule: take a 20-second break and look away into the distance every 20 minutes. Adjust the brightness of your screen so it’s not causing glare. Getting up and walking around periodically also helps give your eyes a break. Proper lighting, ergonomic workstation setup, and blue light filtering glasses or screen protectors can further help reduce digital eye strain for those who work on screens.

Nutrition and Foods That Support Eye Health

  • Vitamin A: Vitamin A is essential for eye health and maintaining good vision. Vitamin A deficiency is the leading cause of preventable blindness in children. Leafy greens like spinach, kale, and collard greens are high in vitamin A. Orange vegetables such as sweet potatoes, carrots, and squash also contain high amounts of vitamin A. Fortified foods like milk, cheese, and yogurt contain vitamin A as well. The recommended daily intake of vitamin A is 700 to 900 mcg per day for most adults.
  • Lutein and Zeaxanthin: Lutein and zeaxanthin are carotenoids found in leafy greens that can help support eye health and potentially reduce the risk of macular degeneration and cataracts. Kale, spinach, broccoli, and peas are excellent sources of lutein and zeaxanthin. Aim for 6 milligrams of lutein per day and 2 milligrams of zeaxanthin. Eggs are another source, especially the yolk.
  • Omega-3 Fatty Acids: Omega-3 fatty acids have anti-inflammatory effects and may help reduce the risk of age-related macular degeneration. Fatty fish like salmon, sardines, and herring contain high amounts of omega-3s. Flax seeds, chia seeds, and walnuts also provide omega-3 fatty acids. Most experts recommend eating fatty fish 2-3 times a week or taking a fish oil supplement with 600 to 1,000 milligrams of EPA and DHA per day.
  • Zinc: Zinc plays an important role in eye health and vision. Oysters contain the highest amount of zinc, with beef, pumpkin seeds, cashews, and chickpeas also providing good sources. The recommended daily zinc intake is 8 to 11 milligrams per day for most adults. Zinc supplements may be needed for some people to meet the recommended amounts.

20 Tips to Protect Your Eyes From Screen Damage

  • Palming: Rubbing your palms together generates heat and energy. Place your warm palms over your closed eyes. Let your eyes relax under the warmth and darkness. Palming helps reduce eye strain and relax the eyes. Do this for at least 30 seconds a few times a day.
  • Eye Rotations: Slowly rotate your eyes in circles, first in one direction and then the other. Rotate your eyes as far as you comfortably can in each direction. Eye rotations help flexibility and range of motion. Do 10-15 reps in each direction, a couple times per day.
  • Focus Shifts: Hold your finger up about 6 inches in front of your face. Focus on your finger for a few seconds, then shift focus to an object in the distance, like a clock on the wall. Shift focus back and forth between your finger and the distant object. This helps strengthen your eyes' ability to change focus at different depths, which starts to decline with age. Do 10-15 reps, a couple times a day.
  • Eye Yoga: Eye yoga incorporates gentle eye movements and massage techniques. Slowly roll your eyes in circles, first in one direction and then the other. Look up and down, and side to side as far as you comfortably can. Gently massage your temples, brow bone, and the area around your eyes. Eye yoga helps strengthen and flexibility your eyes, reduces tension and improves blood flow. A few minutes of eye yoga a day can help maintain healthy eyes and delay age-related changes. Look for tutorials online to learn appropriate techniques.

Recommended Eye Health Supplements

  • Lutein and Zeaxanthin: Lutein and zeaxanthin are carotenoids found in leafy green vegetables like spinach and kale. Consuming adequate amounts of lutein and zeaxanthin may help prevent age-related macular degeneration and reduce the risk of cataracts. The typical dosage for eye health is 10 to 20 milligrams of lutein and 2 milligrams of zeaxanthin per day.
  • Omega-3 Fatty Acids: Omega-3 fatty acids have anti-inflammatory effects and may help support eye health. Fish oil supplements contain the omega-3 fatty acids EPA and DHA, which studies show may lower the risk of dry eye disease and age-related macular degeneration. Most eye care professionals recommend 1,000 to 2,000 milligrams of fish oil three times per day for eye health benefits.
  • Vitamin C: Vitamin C acts as an antioxidant in the eye and may help prevent cataracts and age-related macular degeneration. The standard dosage for eye health is 500 to 1,000 milligrams of vitamin C twice per day. However, high doses of vitamin C can cause nausea, diarrhea, and kidney stones, so you may want to get vitamin C from whole foods as well, such as citrus fruits, bell peppers, broccoli, kale, strawberries, and tomatoes.
  • Zinc: Zinc plays an important role in eye health and vision. It helps bring vitamin A from the liver to the retina, where vitamin A is essential for vision and eye health. Zinc deficiency can lead to night blindness and impaired vision. For eye health, aim for 25 to 40 milligrams of zinc per day. Zinc supplements may interact with some medications, so check with your doctor first.

Make Eye Exams a Priority for the Whole Family

Prioritizing comprehensive eye exams for yourself and your family is one of the most important ways to maintain good vision and overall eye health. According to the American Optometric Association, eye exams should start early and continue regularly through all stages of life.

  • Schedule Exams for Children Early: It's recommended that infants have their first eye exam at 6 months of age, followed by exams every 2-3 years until age six, and annually thereafter. Early eye exams are critical for detecting vision issues and ensuring healthy visual development during formative years. Conditions like amblyopia or "lazy eye" are best treated early.
  • Continue Exams for Teens and Adults: Eye exams should continue regularly into the teen years and adulthood. Teens should have an eye exam before getting a driver's license and at least every two years thereafter. For most adults, comprehensive eye exams every one to two years are recommended based on individual needs and risk factors. Eye exams are the only way to check for vision changes and detect eye diseases like glaucoma, diabetic retinopathy, and age-related macular degeneration early.
  • Monitor Vision Changes in Seniors: Seniors age 65 and older are at higher risk of vision-threatening eye diseases and age-related vision changes. Comprehensive eye exams for seniors, especially those over 75, are recommended every one to two years to monitor vision, check for diseases, and ensure safety. Vision loss can negatively impact mobility, independence, and quality of life for seniors if left undetected.

Eye Health FAQs: Your Top Questions Answered

  • Limit screen time and take regular breaks: Spending prolonged periods looking at digital screens can cause eye strain, dry eyes, and other issues. Take a 20-second break every 20 minutes to look away from the screen and focus on distant objects. This helps reduce eye strain and keeps your eyes flexible.
  • Position your screen appropriately: Your screen should be slightly below eye level so your eyes feel relaxed. This helps minimize the amount of effort required to look up and down between the screen and your keyboard. Make sure there is no glare on the screen from overhead lighting.
  • Adjust screen brightness: Keep your screen brightness slightly lower than the ambient lighting in your room. Overly bright screens can cause eye strain and fatigue. Most devices allow you to adjust the brightness in the display settings.
  • Increase text size: If text on your screen seems too small, increase the zoom level in your web browser or device settings. Larger text is easier on the eyes and helps prevent squinting.
  • Give your eyes a break: Take regular breaks to look away from the screen and focus on distant objects. This helps reduce eye strain from constant close-up focus and provides much-needed eye movement. Even taking short 20-second breaks can help.
  • Practice good lighting: Use overhead lighting when working on digital devices. Make sure there is no glare on the screen. Natural light is best if possible. Task lighting can also help reduce eye strain.
  • Maintain good posture: Sit with your back straight and supported, feet flat on the floor, and your computer screen at or slightly below eye level. This helps minimize tension in your neck and back that can translate to eye strain.
  • Eat an eye-healthy diet: A diet high in vitamins C and E, omega-3 fatty acids, and zinc can promote eye health and may help prevent vision changes related to aging. Focus on leafy greens, fatty fish, citrus fruits, and nuts. Staying hydrated also keeps your eyes moist and comfortable.
  • Don't smoke: Smoking is terrible for eye health and can increase the risk of serious vision problems like cataracts and age-related macular degeneration. Do your eyes a favor and avoid smoking or exposure to secondhand smoke.
  • Get routine eye exams: Have your eyes checked regularly by an eye care professional. Early signs of vision problems or eye disease often have no symptoms. Routine comprehensive eye exams, especially as you get older, are the best way to monitor your vision and catch any issues early on.

Lifestyle Tips for Maintaining Healthy Eyes

  • Reduce eye strain by taking regular breaks: When looking at screens, take a break every 20 minutes and look away into the distance. This helps reduce digital eye strain and prevents potential long-term damage.
  • Get adequate sleep every night: Lack of sleep can cause eye fatigue, dry eyes, and blurred vision. Most adults need 7-9 hours of sleep per night to allow your eyes to rest. Sleep also allows your eyes to produce tears to keep them lubricated.
  • Eat a healthy diet: Focus on eating plenty of eye-friendly nutrients like fish high in omega-3 fatty acids, leafy green vegetables, citrus fruits, and nuts. These provide antioxidants and nutrients to promote eye health and may help prevent age-related vision loss or reduce the risk of certain eye diseases.
  • Do not smoke or vape: Smoking significantly increases the risk of eye diseases like cataracts, macular degeneration, and glaucoma. The toxins in cigarettes and e-cigarettes can damage the eyes over time.
  • Exercise regularly: Maintain a healthy weight and improve circulation. Exercise provides cardiovascular benefits to your eyes and may help control conditions like glaucoma or diabetic retinopathy. Aim for at least 30 minutes of moderate exercise most days of the week.
  • Get a comprehensive dilated eye exam once a year: Have your eyes checked regularly by an eye care professional. Early detection of vision problems or eye diseases is key to preventing vision loss and maintaining your quality of life. Your eye doctor can check for common vision issues and screen for diseases like glaucoma, diabetic retinopathy, and age-related macular degeneration.
