Nutritional Supplements for Eye Health

Lutein and Zeaxanthin are carotenoids (pigments found in plants and retina) which increase density on the retina. It can absorb high-energy blue and ultraviolet light that are eye damaging. These pigments on plants also produce the bright yellow, red and orange colors of plants, vegetables and fruits. For humans, it acts as an antioxidant.

Zinc is naturally found in the eyes and is a powerful antioxidant that protects cell damage. It is a mineral that help maintain the health of the retina, cell membranes and eye structure. It allows Vitamin A to travel from liver to the retina to produce melanin which protects the eyes from UV light.

Vitamin B1 (Thiamine) may reduce the risk of cataracts and reduces inflammation. It plays a role in proper cell function.

Fish is the main source of Omega-3 Fatty Acids. Docosahexaenoic acid (DHA), a type of omega-3 fatty acid, aids in the development of retinal cells. It reduces inflammation and helps cells in the retina and cornea heal and regenerate after damage caused by light exposure and aging. Low levels of Omega-3 Fatty Acids cause dry eye syndrome and retinopathy (progressive damage to the retina).

Vitamin C reduces the risk of cataracts and slows down the progression of cataracts. Vitamin C forms collagen which is a protein that provides structure to the eyes.

In addition to these supplements, using a humidifier in a dry place may help. Also drink plenty of water (1.5L to 2L is recommended to adults daily but varying on weight). Eyes must be also kept moist using artificial tears. Air conditioner filters must also be changed on a regular basis. Environments with air that is dusty or dirty must also be avoided. Cold compresses, cucumbers, cooled green tea bags can also be used on the eyes.

Smoking also damages the blood vessels in the eyes which lead to cataracts and macular degeneration. When outside, protect eyes from UV rays by wearing sunglasses and avoiding starting directly at bright lights. Also maintain a healthy weight and develop a healthy lifestyle. Include green leafy vegetables, spinach, corn, oranges, eggs and carrots on your diet.

It is also important to see an eye care specialist to have your eye health checked.
