Overview of Common Eye Diseases

Your risk of developing an eye disease increases as you get older. The most coarse eye diseases include :

• Cataracts. A condition in which your eyes become clouded. Age-related cataracts are a leading cause of vision impairment and blindness around the world.
• Diabetic retinopathy. Associated with diabetes and a major cause of visual impairment and blindness, retinopathy develops when high blood sugar levels damage the blood vessels in your retina.
• Dry eye disease. A condition marked by insufficient tear fluid, which causes your eyes to dry up and leads to discomfort and potential visual problems.
• Glaucoma. A group of diseases characterized by progressive degeneration of your optic nerve, which transfers visual information from eyes to brain. Glaucoma may cause poor eyesight or blindness.
• Macular degeneration. The macula is the central part of your retina. Age-related macular degeneration (AMD) is one of the main causes of blindness in developed countries.

Although your risk of getting these conditions depends to some extent on your genes, your diet may besides play a major character .

SUMMARY The most common eye conditions include cataracts, macular degeneration, glaucoma, and diabetic retinopathy. Your gamble of developing these diseases depends on your age, genetics, chronic diseases, and life style .

1. Vitamin A

Vitamin A insufficiency is one of the most coarse causes of blindness in the global ( 1 ). This vitamin is necessity for maintaining your eyes ’ light-sensing cells, besides known as photoreceptors. If you don ’ metric ton devour adequate vitamin A, you may experience night blindness, dry eyes, or tied more serious conditions, depending on the austereness of your lack ( 2 ). Vitamin A is alone found in animal-derived foods. The richest dietary sources include liver, egg yolks, and dairy products. however, you can besides get vitamin A from antioxidant establish compounds called provitamin A carotenoids, found in high gear amounts in some fruits and vegetables. Provitamin A carotenoids provide around 30 % of people ’ s vitamin adenine requirements, on average. The most effective of them is beta-carotene, which is found in high amounts in kale, spinach, and carrots ( 3 ) .

SUMMARY Vitamin A lack may lead to night blindness and dry eyes. Vitamin A is only found in animal-derived foods, but your body can convert certain plant-based carotenoids into vitamin A .

2–3. Lutein and Zeaxanthin

Lutein and zeaxanthin are yellow carotenoid antioxidants known as macular pigments. They are concentrated in the macula, the central partially of your retina, which is a level of light-sensitive cells on the back wall of your eyeball. Lutein and zeaxanthin officiate as a natural sunscreen. They ’ rhenium think to play a central role in protecting your eyes against harmful gloomy easy ( 4 ). Controlled studies show that inhalation of xanthophyll and zeaxanthin is proportional to their levels in your retina ( 5 ). One experimental study in middle-aged and older adults noted that consuming 6 milligram of xanthophyll and/or zeaxanthin per day significantly reduced the risk of AMD. The researchers besides discovered that those with the highest consumption of xanthophyll and zeaxanthin had a 43 % lower hazard of macular degeneracy, compared to those with the lowest consumption ( 6 ). however, the tell is not wholly coherent. One meta-analysis of six experimental studies suggests that xanthophyll and zeaxanthin only protect against late-stage AMD — not its early exploitation stages ( 7 ). Lutein and zeaxanthin normally occur together in foods. Spinach, swiss chard, kale, parsley, pistachios, and green peas are among the best sources ( 8 ). What ’ s more, testis yolks, sweet corn, and red grapes may besides be senior high school in xanthophyll and zeaxanthin ( 9 ). In fact, egg yolks are considered one of the best sources due to their high adipose tissue contentedness. Carotenoids are beneficial absorbed when eaten with fat, so it ’ south best to add some avocado or healthy oils to your leafy vegetable salad ( 10, 11, 12 ) .

SUMMARY A high consumption of xanthophyll and zeaxanthin may reduce your hazard of eye diseases, such as macular degeneration and cataracts .

4. Omega-3 Fatty Acids

The long-chain omega-3 fatty acid fatty acids EPA and DHA are important for eye health. DHA is found in high amounts in your retina, where it may help maintain eye function. It ’ s besides authoritative for brain and eye development during infancy. therefore, DHA lack can impair vision, particularly in children ( 13, 14, 15, 16 ). tell besides shows that taking omega-3 fatty acid supplements may benefit those with dry eye disease ( 17, 18, 19, 20 ). One study in people with dry eyes revealed that taking EPA and DHA supplements daily for three months significantly reduced dry eye symptoms by increasing the formation of tear fluid ( 18 ). omega-3 fatty acid fatso acids may besides help prevent other eye diseases. A survey in middle-aged and older adults with diabetes found that taking at least 500 magnesium of long-chain omega-3 fatty acid day by day may reduce the hazard of diabetic retinopathy ( 21 ). In contrast, omega-3 fatty acid fatty acids are not an effective treatment for AMD ( 22 ). The best dietary source of EPA and DHA is oily fish. additionally, omega-3 fatty acid supplements derived from fish or microalgae are widely available .

SUMMARY Getting adequate amounts of the long-chain omega-3 fatty acid fatso acids EPA and DHA from buttery fish or supplements may reduce your risk of respective eye diseases — specially dry eyes.

5. Gamma-Linolenic Acid

Gamma-linolenic acid ( GLA ) is an omega-6 fatty acid fatty acid found in small amounts in the modern diet. Unlike many other omega-6 fatty acid fatso acids, GLA appears to have anti-inflammatory properties ( 23, 24 ). The richest sources of GLA are evening primrose oil and starflower petroleum. Some evidence suggests that taking evening primrose oil may reduce the symptoms of dry eye disease. One randomized controlled study gave women with dry eyes a daily venereal disease of evening primrose vegetable oil with 300 mg of GLA. The study noted that their symptoms improved over a 6-month period ( 25 ) .

SUMMARY GLA, which is found in high amounts in evening primrose vegetable oil, may reduce symptoms of dry eye disease .

6. Vitamin C

Your eyes require high amounts of antioxidants — more so than many early organs. The antioxidant vitamin C appears to be particularly important, although controlled studies on its character in eye health are lacking. The concentration of vitamin C is higher in the aqueous humor of the eye than in any early body fluid. The aqueous liquid body substance is the melted that fills the outermost part of your eye. The levels of vitamin C in the aqueous humor are directly proportional to its dietary inhalation. In other words, you can increase its concentration by taking supplements or eating foods rich in vitamin C ( 26, 27 ). experimental studies show that people with cataracts tend to have a broken antioxidant condition. They besides indicate that people who take vitamin C supplements are less probable to get cataracts ( 28, 29 ). While vitamin C appears to play a protective function in your eyes, it ’ mho indecipherable whether supplements provide added benefits for those who aren ’ triiodothyronine insufficient. high amounts of vitamin C are found in many fruits and vegetables, including bell peppers, citrus fruits, guava, kale, and broccoli ( 30 ) .

SUMMARY Vitamin C is necessity for your eye health, and getting enough of this antioxidant may protect against cataracts .

7. Vitamin E

Vitamin E is a group of fat-soluble antioxidants that protect fatty acids from harmful oxidation. Since your retina has a high concentration of fatty acids, adequate vitamin E intake is authoritative for optimum eye health ( 16 ). Although hard vitamin E insufficiency may lead to retinal degeneration and blindness, it ’ s ill-defined whether supplements provide any extra benefits if you ’ re already getting adequate from your diet ( 31, 32 ). One analysis suggests that consuming more than 7 milligram of vitamin E daily may reduce your risk of age-related cataracts by 6 % ( 33 ). In contrast, randomized control studies indicate that vitamin E supplements do not slow or prevent the progress of cataracts ( 34 ). The best dietary sources of vitamin E include almonds, sunflower seeds, and vegetable oils like flaxseed anoint ( 35 ) .

SUMMARY Vitamin E insufficiency may lead to ocular degeneration and blindness. For those who aren ’ triiodothyronine deficient, supplements probably won ’ t provide an add benefit .

8. Zinc

Your eyes contain high levels of zinc ( 36 ). Zinc is a separate of many essential enzymes, including superoxide dismutase, which functions as an antioxidant. It besides appears to be involved in the formation of ocular pigments in your retina. For this argue, zinc lack may lead to night blindness ( 37 ). In one study, older adults with early macular degeneration were given zinc supplements. Their macular deterioration slowed, and they maintained their ocular acuteness better than those who received a placebo ( 38 ). however, farther studies are needed before potent conclusions can be reached. Natural dietary sources of zinc include oysters, kernel, pumpkin seeds, and peanuts ( 39 ) .

SUMMARY Zinc plays an authoritative function in center function. One study suggests that supplements may slow the early development of macular degeneration in older adults .

The Bottom Line
