   Supplements Feedback: Antioxidants can protect your eyes from damage, but wouldn’t necessarily be expected to improve your eyesight. Certain antioxidants are believed to protect the retina and can be found in vitamins made specifically for eye health. The retina is very metabolically active tissue and free radicals are generated by that process. Antioxidants neutralize the free radicals and protect from damage. Antioxidants can also help protect the cornea and lens from damage due to sunlight. There are many eye diseases where oxidative damage is believed to play a part, even though it may not be the major cause. So a good analogy would be that sunscreen prevents a sunburn but will not cure one - the same with antioxidants - they can prevent eye damage but will not reverse it or improve your eyesight. Unless you are getting VERY low levels of vitamin A in your diet (which is rare in industrialized nations). This can give you problems with your eyesight that can be reversed by getting vitamin A, but do not take more than the RDA of vit. A - it can be toxic.

   Supplements Feedback: In lamans terms antioxidants fight the free radical cells in our body. We are born with some free radical cells, and the enviornment that we live in can cause us to gain some also. We get antioxidants from fruits and vegtables that contain them and the nutrients that our body needs. By consuming antioxidants it can help reduce the chance of some diseases, as to improve eye sight anything can be possible, but I don’t think you may see a major change. I did find one website that talked about the role of antioxidants and eye sight. I posted it below for you to check out yourself.
