As long as I can remember I've had an occasional problem w/ my eyes. I'd wake up w/ pain in one or the other. Didn't happen often, about once every three months or so. The pain lasts only around an hour but I have blurry vision out of that eye for the rest of the day. When I came back here to live the number of episodes abated and I rarely have them now. However, I woke up w/ the pain in the left one on Monday and then today w/ pain in the right. Over the years I've learned to tolerate the pain and I know the eye will be sensitive to cold and light so I didn't go outside or turn on lights for awhile. The blurriness though can cause issues so I try not to read too much. Had library duty tonight. That meant shutting one eye when I read off the computer screen. Have a slight headache now but by tomorrow morning expect that both the headache and blurriness will be gone.
