I have an astigmatism. I have had cataract surgery and didn't chose for implants that supposedly would correct. First, it was several thousand more not covered by insurance. Second, since I know a touch about vision and ophthalmology (took Intro Ophthalmology at the med school during my post doc), I'm a touch of KISS. The alignment of the lens is important and can screw up. A friend of mine chose that and it was a total cluster needing more surgery and never right. Thus, I wear glasses that correct. I like to wear glasses as being old and presbyopic, I need them for reading given my implants. I don't believe in two different lenses for each eye, given stereopsis problems - gave a lecture on that to the med students. Also I always want eye protection for obvious reasons of gun usage and just crap hitting me in the face in real life.
So I've been considering prescription shooting glasses to give more eye coverage. My ophthalmologist (a shooter and also LEO reserve) says my regular classes give good protection as far as impact, though. But the Rx is costly for new glasses, also.
Amazon had a sale on Uvex by Honeywell Hypershock Safety Glasses with total coverage - cheap. I tried them on and sighted through my SRO - 5 MOA. The dot became, I would say about 8 ish MOA and a touch of an horizontal egg shape with a tiny fuzz on the ends. My distance vision is good through them. So I might give it a run for curiousity to see how they work on targets in a match. Just an experiment. It's worth the $10.00 to try.
With my normal Rx, the dot is a nice clear, sharp dot.
