I had problems seeing for 6 months before I was diagnosed! The only thing that helped me was Prednsione.......The Mestinon did not do it for me. My eyes were literally rolling around in my head - too weak to focus - my hubby had to drive me the last few months, as no one really believed how weak I was............

If the meds do their thing, your vision will clear almost immediately - @ least it did for me!
