Do what works best for you. I wear readers and never used them when shooting__until recently. I have some prescription sunglasses and found that they work on really bright sunny days, especially if the sun is reflecting off the target at the range or off of a 200 yd prairie dog. Having learned that, I now shoot some with my glasses on__though mostly not. So do what works best for you depending on the conditions, like shooting targets or prairie dogs on bright sunny days. But, in the squirrel woods__never.
