Thread: Glasses and shooting

When I’m hunting I just wear my glasses and don’t worry about the distortion , it is very small and not really a problem , but it is noticeable and takes a little getting used too .
But if I’m shooting targets or doing load development then I take the glasses off and adjust the scope to my old buggered eyes .
I can’t prove it exactly but I feel that when using my glasses my groups have more of a tendency to have horizontal dispersion.
It’s almost like my glasses are introducing an element of parallax to the scope .

I've also found I get the parallax issue as well. Sometimes everything's all messed up, same hold but it's like your looking through the scope from an angle. Also get the issue of glasses fogging when you breath out, glasses not quite sitting right due to stock etc. It's frustrating but the goddamned image in the scope is just too small now without them. Another problem I've found is the focal distance of my prescription glasses is too far forward. To get around this I use a pair of elcheapo reading glasses from supermarket/warehouse as they just work on straight magnification.
