Yeah, started having blurry dots on my red dot scopes, thought I may have an astigmatism, so went to the eye doctor. Found that it wasn't an astigmatism, but presbyopia (just old eyes). So I have gone to a regular scope that can dial down to 1x and I keep it on that most of the time, works about the same as a red dot for me. With the scope on 1x, I can still use both eyes open. The scope I have is very short, so it doesn't get in my way if I have both eyes open.
