Lyman Hawkeye Shooter's Diopter Optic Aid

[Westwindmike]

As I get older and my eyesight gets worse, I find it hard to focus on the sights of my rifle and still see the target.

Has anyone here ever tried the Lyman or Merit Diopter that sticks on to your glasses? It seems to work for some shooters. I'd just like some opinions on it before I go spend $18-$65 for it.

Thanks.

I've used something similar to this (homemade device) before to focus on far away objects, but not specifically targets. I'm fairly sure it would work the same way; forcing your eye to adjust and focus through the small opening at both the close objects (sites) and something in the distance (target).
