Hey everyone, I suffer from an astigmatism/myopia and was officially diagnosed nearly 10 years ago. I am 26 now. I have a pair of long distance glasses for everyday use, and a pair of intermediate range glasses that I use for computer work and when I'm looking at small screen stuff(smartphone/tablet.) The eye doctor at the time told me my eyes have trouble focusing on small text at intermediate range and would benefit from a bi-focal/computer set of glasses. That worked fine for 2 years, but lately something has suddenly happened. I suddenly now get a really uncomfortable, sort of pressure/pain behind my eyes whenever I look at basically any display...whether it's a PC monitor, tablet, smartphone, etc. It literally takes a matter of seconds to start feeling it, and eventually it will turn into a headache. It's made using my iPhone/iPad almost intolerable, although my 27" computer monitor won't give quite as much discomfort(cheap TN panel monitor.) I went to my eye doctor again and they told me I was fine and that my eyes were just dry. My eyes have always been dry though, but I never had this issue. In fact, the iPhone screen was the only one I could read with comfort for hours without my glasses before this all suddenly happened. I've tried blinking more, increasing font sizes, adjusting brightness, taking more breaks, and limiting my time in front of these devices but it hasn't helped. It's really not due too much time using these devices, because I start feeling discomfort almost immediately after looking at them. I'm going in for a eye exam check up on Monday, but I just wanted to see if anyone has suffered from a similar issue and what they did to get around it.
