I'm a 'tad' bit older at 50 and cannot see anything clearly at a distance (far-sighted). I have to tell you, I find glasses in the woods to be a real pain in the butt. I always had problems with them fogging when hunting in hot weather and perspiring. The problem got so bad that I purchased contact lenses. The problem now is that when hunting, I have problems looking at items that are very close but it still beats glasses! The new contact lenses are sold in pairs but are disposable after a short period of time so even if you buy two, you will eventually use them both.
