Have noticed it for a while now. It happens when I read, obviously, and what it does is causes words on the page to flash and sometimes become hard to read. Don’t get me wrong I can still read, albeit it takes much longer and sometimes I lose interest in the book, but the questions is, what is it?

I don’t think I am dyslexic, but I do suffer from ADD, could that be the problem? or is it the medications I am taking for bipolar? any readers out there experienced the same and have any hints for me?
