I've had myopia ever since I was 6, my whole family has it which leads me to believe its genetics. During my teenage years my diopters jumped from -1.00 to -8.00, its only now steadied and stopped at -9.00 to -9.50 after I passed the age of 18. My parent's have always told me that myopia will lead to blindness if I don't strictly follow optician's suggestions to lowering it. I never believed them, and even now I don't think blindness is a big probability. But I've always been very worried that it might be true and I might be at risk. So I wanna hear some professional opinions. How likely am I to go blind either now or later as I age? I wear contacts almost daily now if that matters. I have no flashes, and very very occassionally do I see black spots flashing briefly at the very margins of my eyes, like twice or so in a year. Besides that there really is no noticeable damages to my eyes. So, opinions please.
