One vitamin that is essential for eye health is lutein. The human body is completely unable to produce enough lutein to sustain the eye so it is necessary for you to get this vitamin elsewhere. It is believed that your body needs at least 6mg of lutein each day for optimum eye health. Since it is difficult to get enough lutein in your diet through eating healthy foods, it is important to take lutein supplement. You can go through the manual in the package or bottle to make sure it contains the essential amount of lutein.

Vitamin C, Vitamin E, beta-Carotene (pro-Vitamin A) and Carotenoids (Lutein & Zeaxanthin) are strong antioxidants i.e. they protect the eye against free radical damage. It seems reasonable to assume that strengthening of the eye defences by increasing the intake of these vitamins would be helpful in preventing the chronic AgingEye diseases. Recent well designed and controlled studies seem to support this assumption. Lycopene (a different type of carotenoid found in tomatoes) protects against prostate cancer and heart disease - therefore the protective effect of these vitamins is not just restricted to the eye.

Among these are the antioxidant vitamins. The eye, especially the lens and the retina is particularly vulnerable to the effects of unchecked free radicals which are a byproduct of oxygen, cellular processes and environmental contaminants. Antioxidant vitamins help to combat free radicals. The primary antioxidant vitamins include Vitamin A, Vitamin C, and Vitamin E. in addition to their important action against free radicals they promote healthy cells and tissues in the eye. Lutein and Zeaxanthin are two more valuable antioxidants that recent research has found to be especially effective in maintaining the good health of the eyes.

Vitamin C found in fruits and vegetables such as; oranges, strawberries, rosehip, broccoli. Appears to reduce pressure in Glaucoma, slows deterioration in macular degeneration and reduces the risk of cataracts. Antioxidant.

A balanced diet, with plenty of fresh fruits and vegetables is good for your eye health. Eating a diet low in saturated fats but rich in omega 3 fats and micronutrients derived from green leafy vegetables, fruit, fish and nuts may help prevent and slow down the progression of AMD and age-related cataracts.

Vitamin A found in carrots, sweet potatoes, and liver. Deficiency is tied to blindness, and corneal ulcers. Use may reduce risk of cataracts, and night blindness. Antioxidant. Reported to improve night vision.

Vitamin D: This vitamin is vital for the metabolism of calcium and regulates the absorption of calcium and phosphorus from the intestinal tract. A deficiency of vitamin D results in rickets in young children; irritability, weakness, and softening of the bones in adults; and underutilization of calcium and phosphorus in bone and tooth formation in people of any age. Vitamin D may have a direct effect on the eyes, and it is vital for maintaining overall good health.
