I've done some searching to see about finding red dot sights that may have diopter adjustment, came up with only a Leupold model that doesn't specifically say it does so in the specifications. The problem I have with red dots is the "dot" isn't a dot for me, it's a blurry star burst at best. I understand that finding the correct light intensity level is vital but that really makes no difference with what I see. It's may be related to the fact that I'm farsighted in my dominant right eye. When I peer through using my nearsighted left eye, by golly, it is a dot after all. I don't wear prescription glasses. Anyone run across a red dot sight that allows for dot focus?
