I know I'm new here and all, but I've been shooting IDPA for about 3 yrs, and pistols in general for many, many more. I'm badly nearsighted with progressive lenses. To see the front sight in focus I had to really tilt my head back. A few years ago I had my optomotrist make me a pair of shooting glasses. I'm right handed and right eye dominant, so my right lense was focused about 1.5" past the tip of my right pointing finger when both hands are simulating a free-style grip. This puts the right eye point of focus about to where the front sight would be. My left lens is distance focus, both are single Rx. These glasses are probably the best thing I have done to improve my shooting.
