‘i’-Vitamins, Minerals etc

To function properly your eye needs a constant supply of nutrients, and it needs a variety of foods to make sure that ocular tissues can use those essential substances. Some substances are destroyed in the visual process whilst others are needed to protect ocular cells.

All the food substances that your eyes need can be obtained by eating a varied diet, but if you are unsure that you are getting all you need then it might be advisable to take a supplement – just don’t over do it (too much of a good thing is not always good for you)!
