Hi, I can't concentrate on reading. Once I start, I can't keep focusing. My refraction is 20/20 +0.5(2.75 cyl) for both eyes. I went to two doctors, had regular eye exams, checked the retina, did corneal topography but I still can't read as I was 1 year ago. Some thing I think may be abnormal is that since two years I see ghosts from my right eye, which increase after focusing for a while. I was told these are HOAs as they disappear when l look through a pinhole or closemy eyelid.
