I've seen many results with it in general. Eyesight was one I wasn't really aware of until recently. I do notice nuance in colors more than before. But I can't really say it's a night or day difference. Blacks are blacker, browns show hue better, etc.

After you do a 10 minute session for example and look at a monitor, you see significant contrasts for awhile until your eyes re-adjust. I like to think that it is doing something and is why I keep doing it outside the mood/skin/etc benefits.
