What is your age and sex? How long has this been going on? What makes it better? Are you having any decrease in vision?
Have you been doing more work than usual requiring your eyes to focus more, as in sitting at a PC longer than usual? Do you have glasses that you usually wear and if so have you been wearing them? Is that discomfort in both eyes? Have you tried some ibuprofen? Any medical problems or other associated symptoms?
haven't been working more than usual. I don't wear glasses. yes, discomfort is in both eyes. I haven't tried ibuprofen but I will now. I've no other symptoms or medical problems.
I was in Boston, USA last weekend for a few days and flew back to Dublin on Monday night. It was only a 6 hour flight and a 5 hour time difference. Could this have anything to do with it? I have been well rested since so wouldn't have thought so.
