I am 43 years old male with lazy right eye. This eye was operated in 2005 for cataract due to high myopia. Now since last few months i am having droopy upper eyelid. I get tired while i concentrate on any book, computer or even driving for 20 minutes. Tiredness in the eye rgion. What could be the reason and what exact words should i use while saying this to my opthalmologist because they are telling me about eye exercises which is not working.
