DB,
I need glasses for distance, and when I use a red dot w/o my glasses they look like a starburst. With glasses on the dots are sharp, especially on an aimpoint. That might be why it was fuzzy to you. I have red dots on hand guns, my 10/22 TD, and one of my ARs, and love them.
Funny when I shoot with scopes I dont use my glasses, but look over them.
