Was near sighted (around +8.0) and got Lasik 2 years ago. Now my eyes have settled to be slightly myopic (around +1) and a have a slight astigmatism in one eye. Starting about a year ago, I began to experience extreme eyestrain and headaches after using a computer and reading or TV to a lesser extent. The headache almost always concentrates behind one eye whereas the other eye feels mostly normal.
Over the past months, I have taken the many obvious steps suggested for computer vision syndrome, like adjusting my monitors brightness and distance, environment humidity, using lubricating drops, blinking often, taking breaks, personal diet, etc. I have gotten regular eye exams to ensure my prescription is keeping up to date with the post-lasik fluctuations, and even got a second pair with a slight plus power to help ease the strain.
The latest hypothesis is the possibility of convergence insufficiency. My doctor did a convergence insufficiency test using a bar with varying size prisms and concluded I have convergence insufficiency. I have been doing exercises in which I keep an object in focus at varying distance (pencil pushups). I can keep an object in focus indefinitely at any length until about 2 inches from my nose at which point the object gets blurry. Is this normal or indicative of convergence insufficiency? My computer monitor is much farther away than 2 inches and I can focus on it fine, yet my eyes strain. Can eye exercises remedy my situation and what are nest to do? It seems like something drastic must have happened because I used to be able to work all day.
