Do I have ptosis overcorrection in my right eye? My dr says it's normal. I feel constant pull and strain to blink.

You are frankly over corrected in the right side. The most common type of ptosis surgery offered is a mueller's muscle conjunctival resection ptosis surgery. Is that how your ptosis was done or was all the work performed from the front of the eyelids.  This will make a difference regarding the likely cause of the over correction of the eyelid. I regard an over corrected eyelid after ptosis surgery as an emergency. I do not allow these eyelids to heal this way. Generally I recommend immediate surgery to prevent the eyelid from scarring in the over corrected position. That moment would have been 24 hours after surgery. Even at 2.5 weeks after surgery, there is something to be said for exploring this eyelid and determining what can be done to release the eyelid and not allow it to persist like this. There is no substitute for a personal assessment. There is help out there for you you but understand that your surgeon may not be able to understand what is going on.
