Improving Eyesight Naturally

I came across this video by Dr. Mercola about improving your eyesight naturally, and I found it very interesting. 

I actually quit using my glasses a few years ago for various reasons. Surprisingly, I haven't needed them as much since I stopped wearing them. 

I think this video has some helpful tips, and it made me curious about what other things I can do to improve my eyesight naturally. As I discover more information, I'll share it with you. 

Enjoy the video and let me know your thoughts as well.
