Not sure if this belongs in this forum and I apologize if it doesn't. I just thought I'd share a tip with some of the people in here that may wear prescription glasses. I am one of those people, I have about 18/20 vision uncorrected which means in reality I can get away without lenses. However my optometrist (also a good friend and avid shooter/hunter) opened up a whole new world. According to him optometrists will generally only correct vision to 20/20 and consider the adjustment a success. Normally this may be true however there are many people that can have their vision corrected even farther if the optometrist takes the time to get the optimum lens configurtion down right. My vision with glasses is a bit better than 20/10 which apparently is about as good as a humans can possibly be. The amount of detail discernable at even extreme ranges is unbelievable. It is possible to pick out deer and coyotes at ranges that most people would require binoculars or scopes. This is a great advantage as most peoples vision begins to blend objects and colors at a few hundred yards. So if you wear prescription lenses as your optometrist if you can squeeze a little extra out of your glasses you won't regret it come hunting season.
