You'd need to do like the 3D shooters and have somebody in the stand with you to hold an umbrella to shade your scope... It's amazing how scopes can turn shooting a bow into a 2-man operation. I have heard of guys using them for hunting, but I wouldn't recommend it. And, again, some states do not allow magnifying sights on bows. Same with electronics.

Fieldmouse, wearing glasses doesn't qualify as a disability under the ADA... unless you're legally blind even with corrective lenses. But I'm sure you could find a shyster lawyer to take the case.
