Had cataract surgery on both eyes last year. I have an astigmatism which was not corrected (due to cost).
Prior to surgery, my only problem when shooting pool was glare and reflection from the table light.
Now, I see well enough that I don't need to wear glasses when I shoot.
However, to really see a shot clearly, I have to blink several times, otherwise the edge of the balls start to look fuzzy. That is to say, my fake eye lenses seem to require more tears to stay hydrated to the point where my vision isn't affected. I don't have any problems with dry or itchy eyes, but blinking does help clear things up.
Shoot safe.
