Not sure, it was the cheap model. Seriously, I had 20/15 vision after surgery.
I'm beginning to lose a little of closeup.
I still read without glasses unless it's very small print.
I've had glasses for distance almost all my life, but close up was no problem. Over the years the distance got better but closeup got worse. It's a conundrum, I can clearly see at a distance who I'd like to do it with but on the other hand I can't see who I am doing it with. What's a guy to do?
