Vision correction for red dot sights?

Im not sure if this belongs here or in Equipment but seeing seemed sort of fundamental.  What have people with corrected vision learned about dealing with dot sights? I have only shot a few rounds through a dot sighted gun and done some dry firing through my own. I think I'm seeing the dot OK and the BE seems about as clear as it should with irons. Is that as good as it gets or is there a better way?

I just use normal distance correction for the dot sight. I can see both the dot and the X clearly at 25 and 50. I do the same with a scoped rifle for silhouette or long range.

I have a buff 3/4 inch paster to block the vision of the sights with my left eye but still allow me to scope or score.
