Am 61 year old hipower M-14 service rifle competitor having progressively increasing vision problems. When looking through rear aperture, front post aligned, but not yet with sight picture, aiming black well above front post, I can see everything reasonably well, including the aiming black. But as I move into sight picture, as the front post nears the aiming black, the aiming black begins to gray or white out. First saw this problem only at 600 yards prone slow, but over the years the problem has moved closer, and at a match this past weekend saw the problem at 200 yards. My guess is that light rays coming from the target white are being refracted by the front post, and my eyes are seeing target white rays where the aiming black really is. The problem isn't 100% consistent. Two weeks earlier, at a full 600 yard range, with a light and dark day, I had reasonably good vision for prone slow. But last weekend, at a 300 yard range, intense clear sky, I had terrible vision for prone slow. Same rifle. Same carbide lamp blacking. Same efforts to oxygenate and minimize time looking through the sights. I'm guessing a possible solution is to replace the standard width front post with a custom made front blade,the theory being the narrower the front sight, the less the refraction. Any suggestions?
