Gentlemen,
Forget all that expensive glass to cover up a problem that needs to be fixed. If you have cataracts, get 'em fixed. If your eyesight is failing because of old age, get 'em fixed. Lasik with wavefront technology is the answer and in the long run far cheaper than buying optics for all your guns. Best decision I ever made. 20-10 both eyes. Literally, in and out in 5 minutes, both eyes. I never saw this good before. Here's the gratuitous pic.
And yes my eyes are blue. I still have to wear glasses for up close work, 58yo. WC145 this is especially for you. So dig your way out of the snow mound you call a house and run, don't walk to your best Lasik Clinic around. You may have to go allaway to Boston to find a good one.
