There are a ton of studies that show that low carb diet and antioxidants improve vision.

Or you could just ask people that take them. My eye doctor asked about my vision and after I told him mine improved - he said I was like the 3rd or 4th person to tell him that.

What is funny is there are numerous studies about people on gastric bypass surgery that don't take their vitamins - and almost become blind. After a couple of months on vitamins - there vision returns to about normal.

But this study, and many others out there are FUD - fear, uncertainty, and doubt that anything other than what your doctor prescribes is a waste of time and money - and could be dangerous!
