Gettin' old sucks, doesn't it. You might try .019 pins and see if they help. Smaller pins are better on longer distance targets anyway. Those big .029 pins cover up too much of the aim point on distant targets. I don't know how your eyes react to different colors, but I always found green to be much clearer than red or amber. Some guys say blue is especially nice at cutting down the haze too, but I never tried it.

The only real solution I found for my aging eyesight was to take the sights off, pitch 'em in the junk drawer and shoot barebow.
