I never had any trouble with my eyes, except for the fact that I have to wear glasses ever since I was eleven (I'm wearing lenses since I was 13). My eyes are right now -2.50 at the left and -1.75 at the right. Not a big deal. But yesterday I woke up and all of the sudden I started to see dubble with my right eye. I never had that before and my eye still didn't get any better. Does anyone know what it means?
