Hi Godzgirl, Honestly, that doesn’t sound like eye-strain unless you can link it with the use of your eyes (worse while reading — stops after reading — that sort of thing). I believe the best way to get to the bottom of some of these weird symptoms is to look at the OTHER symptoms you may be having, to try to find a commonality. Does that make sense? Nothing stands alone in these crazy conditions. What other symptoms do you have? Gentle hugs…
