I'm planning to see another opthamologist since I have to get tested for something else, and I'm also going to bring up the issue with the glasses. The points you bring up are good, but I thought I could just get away with just using them for driving. There are other people who wear glasses, but it seems to be only when they do something specific, like reading, or driving. They could be wearing contacts for all I know though.
Just out of curiosity, I'd like to see what my results would be if I took the Snellen eye chart test without glasses. When I had my appointment, I took the test with the glasses on, just to get the best results.
I thought of using contacts, and thought they might be better, but I'm going to discuss that with the eye doctor when I see one again.
Since you too say the pressure can be annoying, what exactly was it like for you at first? Was your situation the same as mine? What you told me to try is what you also tried to get over the issue, yes?
Anyway, I've had sinus headaches, so you might have a point about sinus problems. I've even considered seeing a neurologist. I find that I can also get headaches from certain strong scents (like strong perfume or strong cologne, and that's why I never wear cologne), not eating breakfast soon enough, or not getting enough sleep at night before waking up in the morning.
