If CYL is over prescribed, can that cause directional blur as well? I have a feeling my CYL is over prescribed and intend to talk the eye doc down a little in few days, but I am seeing some directional blur in one eye. Does that HAVE to mean the CYL is too low, or could it be too high (he gave me glasses with less CYL correction than I had been using last)? If the SPH is too low will it make existing directional blur more apparent?
When you do have CYL lowered just right, how much directional blur will there be?
