I emailed my optometrist. He told me to bring my gun in a suitcase and to have an orange chamber block in the gun. When I came in his people had a normal procedure they ran me through. When the Doctor came in he closed the door so we would not scare anyone. We played with lenses on my dominant eye so I could see the back of the front sight on my gun crystal clear. My non-dormant eye was set up like my normal prescription for that eye. I purchased ESS Crossbow glasses that have an inside lense piece to place prescription glass in. The outside has wrap around safety lenses that can be changed also. Clear for indoors and gray for the outside. Other manufacturers like RUDY and Oakley offer the same thing. ESS were the cheapest. I switch to my shooting glasses as soon as I get to the range to let my mind adapt to the glasses. Now no issues adjusting. Great for shooting. If I am ROing seeing the targets for scoring I have to get close.
