This is one of the few supplements where I notice a difference the same day I take them. When my eyes hurt, I take a couple of capsules and - voila! - eyes are better.

I took this for one bottle only and then asked my eye doctor about it. He said it was better to get my lutein and other vitamins to strengthen the eyes via food rather than supplements. He said it wouldn't hurt but was probably not necessary. I'm not into throwing my money away so I didn't continue taking after the bottle was gone.
