Carla, I also have read that the inability to see things close up was called farsighted (ie: because you could see distant things well) and the inability to see things far away was called nearsighted (because you could see near things well). I think, when I have the time, I will look it up. Also, does anyone out there experience a transient gray fog covering their vision so that it looks like they are looking through a gray cloud - no matter what the distance?
