Vitamin A plays an important role in vision It helps protect the surface of the eye which help prevent eye infections. We’ve all heard how carrots help eyesight because they have Vitamin A. It’s true! It helps reduce the progression of macular degeneration, a cause of blindness. Vitamin A is found in sweet potatoes, spinach, and kale. It’s in also in eggs, beef, milk, and cheese. Vitamin A plays a crucial role in vision by maintaining a clear cornea, which is the outside covering of your eye. This vitamin is also a component of rhodopsin, a protein in your eyes that allows you to see in low light conditions (1). Vitamin A deficiency is rare in developed countries, but if unaddressed can lead to a serious condition called xerophthalmia. Xerophthalmia is a progressive eye disease which begins with night blindness. If vitamin A deficiency continues, your tear ducts and eyes can dry out. Eventually, your cornea softens, resulting in irreversible blindness (1, 2). Vitamin A may also help protect against other eye afflictions. Some studies suggest that diets high in vitamin A may be associated with a reduced risk of cataracts and age-related macular degeneration (AMD) (3Trusted Source, 4Trusted Source, 5Trusted Source, 6Trusted Source). For general eye health, vitamin-A-rich foods are recommended over supplements. Sweet potatoes are an excellent source, as are leafy green vegetables, pumpkins and bell peppers (1). Summary Severe vitamin A deficiency can lead to xerophthalmia, a serious condition that can result in blindness. In some studies, high amounts of vitamin A intake were associated with a reduced risk of cataracts and age-related macular degeneration. 2

Most of our vitamin D comes from sunshine on our skin Some foods have small amounts of vitamin D. Most people need a vitamin D supplement, especially those who spend most of the time inside use sunscreen are overweight darked skin or elderly The best way to know how much vitamin D to take is to first get a blood test. Goal is 40-60 ng/ml Vitamin D may help protect us from macular degeneration and dry eye

Vitamin E helps decrease the risk of age-related macular degeneration and cataracts Before taking vitamin E supplements talk to your doctor or dietitian about the right dose and possible side effects. Foods high in vitamin E include fortified cereals, sunflower seeds, nuts, olive oil, canola oil, avocados and tropical fruits. Vitamin E deficiency can affect your eye’s retina, affect balance and muscle strength. Vitamin E and antioxidants helps promote eye health

Lutein Lutein is concentrated in the retina which is in the back of the eye and protects the retina from damage. Lutein is also found in the peripheral of the retina, a lutein deficiency can reduces our sense of motion You can get enough lutein in your diet if you costume a variety of vegies daily like kale, collards and spinach, or fruits like kiwi, grapes, raspberries, peaches and oranges.

Zinc is concentrated in the eye, mostly in the retina and choroid, the tissue lying under the retina. Its a powerful antioxidant that protects against cell damage. What are the best foods for zinc? Beef, pork, beans, nuts, oysters, yogurt, fortified cereal, and legumes to mention a few Zinc helps our retina produce melanin, that protects our eyes.
Slide 11-

Omega-3 fatty acids are found in canola and olive oil, and in many foods Omega-3’s help protect adult eyes from macular degeneration and dry eye. They help drainage of intraocular fluid from the eye, lowering the risk of high eye pressure and glaucoma. People who use olive or canola oil are less likely to get age related macular degeneration. Oily fish have omega-3’s are tuna, wild salmon, trout, mackerel, sardines, anchovies and Herring.
