I’ve been slightly aware of endmyopia for almost 10 years and kind of following it for about 2 years. I never measured my eyes at their worst and have no idea what the first prescription I had was.
My experience is that my eyesight is pretty good now without correction in bright sunlight, and really bad indoors in low light particularly reading the image on a screen projector in church. I would say to correct adequately in church would take around -2, but I was able to read the finest print on the drivers license screening test wearing -1 lenses. Due to some mistake I again have no vision restriction on my drivers license although the DOT medical card is a different story.
I think I’m at a plateau, which outdoors feels like the last diopter, but really is somewhere around -2. Every few months I can tell that there are certain situations in which my vision has improved, while other situations seem stagnant.
