Hi, I ve been having some issues with my eyesight for the past year or so, and I m not sure what s going on. It seems that every time I read for about 20 minutes or so and then try to focus my eyes on some other objects around me, my vision is very blurry and I can t see as clearly as I used to. It also happens when I use the computer, or do anything, really, that includes staring at something for at least 15-20 minutes straight. I thought it might just be dry eye but I m kind of worried that it might be something else.
