Healthy vision or good eyesight requires certain nutrients from a healthy diet or eye supplements. The Dietary Guidelines for Americans recommends that a healthy diet should emphasize fruits, vegetables, whole grains and fat-free or low-fat milk and milk products. It should also include lean meats, poultry, fish, beans, eggs and nuts. In fact, many Americans take a diet that is high in calorie but low in nutrient. A healthy diet should still low in saturated fats, trans fats, cholesterol, salt and added sugars. If your diet is not healthy enough, multivitamins and mineral supplements can offer enough nutrients that your eyes needs.
These supplements protect you from degenerative eye diseases such as macular degeneration and cataracts. The Age-Related Eye Disease Study (AREDS) investigated the natural history and risk factors of macular degeneration and cataracts and evaluated the effect of high doses of antioxidants zinc on the two diseases’ progression in the 1990s. AREDS recommended a formula that can significantly reduce the risk of advanced macular degeneration. The formula contains Vitamin C, E and A, Zinc and copper. AREDS also found that antioxidant eye vitamins can decrease the risk of developing cataracts. A follow-up study named AREDS2 aim at evaluating the effects of other nutrients such as lutein, zeaxanthin and omega-3 fatty acids.
In detail, vision multivitamins should contain certain ingredients. These elements are essential in preventing the deterioration of degenerative eye diseases. Vitamins A helps maintain night vision and heal wounds. Vitamin B complex including B1, B2, B3, B5, B6, and B12 helps decrease chronic inflammation and prevent macular degeneration as well as treat uveitis. Vitamin C and E are also included by the AREDS formula. Lutein and zeaxanthin may also play a role in reducing macular degeneration and cataracts. While phytochemical antioxidants protect eyes from oxidative stress, omega-3 essential fatty acids have been proved to lower the incidence of developing dry eye.
Among various multivitamins solutions, popular brands such as ICaps, Ocuvite PreserVision, Oculaire and MacuTrition are more convincing. Some tips are important when you choose multivitamins. You should check the expiration date and the bottle seal. Doses are also critical that you must strictly follow the dosage instructions on the bottle. Supplements that contain filters such as dairy products, corn and wheat are not suitable for people with allergies. High bioavailability enables your body to absorb nutrients more easily. And capsules are also easier for absorption than hard tablets.
You should also be aware of safety issues while taking eye supplements. Pregnant and nursing individuals need additional care.

Macular degeneration can cause irreversible vision loss. Although there is no effective cure of AMD, a variety of prevention measures are available to reduce the risk of AMD, especially for older people.
The University of Manchester said that smokers are up to four times more likely than non-smokers to suffer AMD. For old people, it is a necessity to stop smoking.
People consuming many vegetables rich in carotenoids are reported to have a 43% lower risk of AMD than those seldom eat these foods. These vegetables include dark, leafy greens, especially raw spinach, kale and collard greens.
Older people can not absorb enough nutrients from diet alone, so that nutritional supplements including vitamins and minerals are useful to improve eye health.
For people at high risk of developing advanced AMD, the Age-Related Eye Disease Study (AREDS) has found that nutrients play a key role in maintaining their current vision. The formula of nutrients recommended by AREDS includes vitamin C and E, beta-carotene, zinc oxide and cupric oxide. The study shows that this formula can lower the risk of advanced AMD by 25%. But for smokers, AREDS recommends other nutritional formulas that exclude beta-carotene, which may increases the risk of lung cancer among smokers. Some researchers also oppose formulas with high-dose vitamin E, while others just eliminate its tiny risk.
The British Journal of Ophthalmology has conducted a study of 4000 old people, which showed that regular exercise such as walking can bring down the risk of AMD.
Both Massachusetts Eye and Ear Infirmary and the University of Sydney have revealed that high consumption of fish reduces the risk of AMD.
Both Harvard Medical School and the Massachusetts Eye and Ear Infirmary have demonstrated that AMD can be decreased by daily fruits and nuts eating.
High glycemic index in refined foods causes a rapid increase in blood sugar and insulin release, which in turn increase the risk of AMD. So that the old should take low glycemic index foods, such as fruits, brown rice, grain breads, apple juice and carrot juice. High index foods including white bread, white rolls and donuts should be reduced.
Cumulative eye damage caused by overexposure to UV and HEV lights are estimated to arouse AMD, so that you’d better to wear sunglasses outdoors.
Cholesterol built-up in blood vessels can inhibit blood flow, which is harmful for healthy eye tissue. In this case, cholesterol controlling can protect the old from AMD. Since high blood pressure is also indicated to have link to AMD, blood pressure controlling is necessary.
Early detection and treatment of AMD can minimize the risk of vision loss caused by ADM. People between 45 and 60 are recommended to take an eye exam every two or three years, and people above 60 should take an exam every year.

Cataracts have become one of the most significant causes of blindness, so that a large number of studies and researches are focusing on the way to prevent cataracts or slow down their progression. Herbs have been proved to be effective in decreasing the risk of cataracts in mice, but relative researches in human body are rare. You should be cautious about taking herbs as a medicinal remedy. Many more studies are now underway about the influence of a healthy diet on cataracts prevention. Antioxidants and certain vitamins are considered possibly effective to decrease cataracts and slow their advancement.
Exposure to pollution, chemicals, smoking, radiation exposure and unhealthy foods can cause free radicals, which in turn lead to oxidation in human body including eyes. Free radicals in the body have unpaired electrons so that they stole an electron from another molecule. This unpaired molecule in turn tries to get an electron from another molecule. In this way, many healthy cells of organs and other tissues will be damaged. This process is named oxidation, which damages proteins and fats in the eye’s lens and causes cataracts.
Be clear of the principle of oxidation, nutrient experts recommend antioxidants including some vitamins and phytochemicals to reduce oxidation formation so that cataracts can be avoided. Studies have showed that antioxidants such as vitamin C, A and E and lutein have potential effect in preventing cataracts. Antioxidants can be found in foods such as fruits and colorful or dark green vegetables. These vegetables also contain folic acid and calcium, which may also reduce the risk of cataracts.
In this consideration, experts recommend a healthy diet that includes fruits, vegetables and whole grains. Fish are rich in omega-3 essential fatty acids, which may be also effective. An exactly healthy diet should contain nine servings of fruits and vegetables, three serving of 100% whole grains every day and two servings of fish every week. And the daily calories consumption should not exceed the basic need to maintain a healthy weight.
People still have different opinions about the sources of those nutrients, antioxidants and phytochemicals. In the market, dietary supplements are available in many forms. While some experts insist on a healthy diet, others argue that dietary supplements are helpful addition to even a healthy diet.
A healthy diet should avoid unhealthy foods such as fried foods, processed foods, sugary foods, and foods rich in sodium. High consumption of salt and sugary may increase the risk of cataracts. Extra soft drinks, desserts, greasy snack foods and fast foods should also be reduced or stopped. Just enjoy delicious fruits, vegetables and fresh fish.
