Aside from the issue of objects being in focus, there is also the issue of depth perception. There is more at stake than just seeing clearly -- it is very important to your pool game that proper spatial perception is maintained. I am very near-sighted, and the lens required to correct my "intermediate" vision (3 to 12 feet) to 20/20 drastically affect my depth perception. On the other hand, I have contact lens which adequately correct my intermediate vision for pool but result in no ill effects on my depth perception. The issue of depth perception must be included in any discussion of this matter.
