I'm not sure how old you are but when I was about 38 my eyesight started to go. I needed to wear reading glasses for close stuff now I'm 51 (ugh.. how the heck did that happen..hahaha) and I'm on my 5th prescription in as many years (5). Depending on your age that could be part of the problem. I always had eyestrain when I would be examined.. because of straining. I also have chronic dry eye. That can really mess with your vision, due to the dryness.
But the big question is why are you suffering from the pushing on your eye.. Get your bloodpressure checked. The same thing was happening to my mom to (or at least what I think the same thing is), the eye doctor told her to check her BP and it was skyrocketing. All it took was getting her BP meds straightened out and she never had a problem again (that all occured 8 years ago). I hope its that simple for you, too.
Keep us posted on how you're doing. I'll be interested in what you learn.. my husband is legally blind and eye issues really fascinate me.
After I wrote the .. Shucks post, I felt terrible I never meant to say I "hoped" it was high blood pressure.. sorry about that!!
I really hope you can get a simple answer. That's what I SHOULD have said!! Duh!!!
