Since this thread is getting into various eye problems It should be a good place for this link I found written by an eye doctor who is a shooter.

It includes several articles on Red Dots and more important a piece written by a shooter eye professional for other eye professionals to help them understand a shooters visual problems and needs. You should share this with your eye care professional.
