Can carrots really improve eyesight?

Once when I was little, my mom told me that eating more carrots could improve my vision. I believed her and went through a crazy carrot phase where I ate carrots practically 24/7. My skin started to turn orange, and so I stopped. I didn't notice an improvement in eyesight, in fact, I needed glasses just a few months later. http://www.snopes.com/food/ingredient/carrots.asp has the truth behind the myth, and how it came about.
