It is true in that carrots are high in Vitamin A, also known as retinol. Retinol is converted to retinene, a compound that makes up part of the light-sensing photopigments that sit in the retina and help convert the light that enters your eye into nerve signals. The more photopigment you have, the better you are able to detect light. Therefore, in situations where less light is hitting the retina (ie, you're in a dark room), and the more photopigment you have, the more likely you will be able to convert that scant light into a nerve signal which can travel to your brain. So, vitamin-A rich carrots can help you to see better in the dark, but they do not improve your visual acuity. That is, your vision will not improve from 20/400 to 20/20 by eating carrots. That's more a function of the shape of your eyeball, the clarity of the lens inside your eye, etc. source :http://answers.yahoo.com/question/index?qid=20061204131830AAFU20Y

Carrots have a lot of beta-carotene and Vitamin A which are supposed to be good for your eyesight. The whole thing with carrots is considered an urban legend made up by some officer but I think it might work.They won't make wonders if you're on the computer all day or are legally blind but there is no harm in trying,right?
