switched to glasses, took some time but better now
Due to missing long shots, as I couldn't really tell what part of the fuzziness to hit, I requested glasses from my optometrist....I usually need reading glasses, but my distance has dwindled some as well. The first night I shot pool, which was for about 3 hours, I had quite a few issues with the glasses. I always seemed to be looking over the top on them, so the ridge was bothering me, and as mentioned, I seemed to lose a little of the periphery vision for long angle shots. Wanted to just give them up. However, I pushed the nose bridge supports closer together, and now the glasses sit up just enough I can see through them. I think your eyes/mind need to have a period of time to readjust, as now I can see the angle lines fine. In fact, I make many more thin long cuts now since the object ball is much more distinct. Try a few adjustments, give yourself a few times shooting, and I think you'll find the benefits will begin to show up. It is a little strange at first, but part of the problem, in my opinion, is that your brain isn't used to seeing objects so clearly, so it's a little mystified until that type of sight becomes normal.
