I have had intermittent strabismus my whole life where the eye I don't use will cross inward. I'm 24 now. For most of my life the crossing was not very bad so it didn't bother me a lot. But over the past 3 years my right eye has become a lot more crossed and I have lost the ability to switch eyes without forcing it. My right eye stays crossed unless I force it to work by closing the left eye and gazing to the far right. This is too much work so I only use my left eye now.

I have an issue where surgery is not an option for me. I've gone to three different doctors and they all tell me there is nothing I can do to straighten my eyes besides surgery.

Is this really true?? There are no other ways?
