FYI: Just wanted to pass along some info that may be helpful to anyone with poor up close vision. I've had trouble focusing on the front sights of my handguns for sometime. Scores and shot placement have been suffering. Read an article in SHOOTING TIMES (March 2001) about a solution for aging eyes. Took the article to my optometrist who hunts turkey and found it very interesting. In short, he ordered my glasses with yellow tint and bifocals. But, the right lense for my shooting eye has a low prescription that allows me to see the front sight clear. The left lense is clear. If you hold the glasses up to the light, you can see a slight difference between the left and right lense. A word of caution. The glasses in my case work great on the range. No problems walking or seeing far away. However, I just discovered a problem. They are not real good for hours of wear walking in the woods and you cannot focus binoculars. So, I went back to the eye doctor and re-ordered trifocals. This way each lense will be the same. I'll have to move my head up and down for a clear sight picture, but I'm sure that will come easy with practice. Hope they work. Just wanted to pass this along for anyone else with this problem.
