How bad is -14 eye Power for myopia? Will it eventually result in blindness?
A
lens Rx for -14 Diopters tells us you have a very, very high degree of
nearsightedness (myopia). This would be considered in the "severe" range. Of
all the people who are myopic, less than 2% are worse than -10 Diopters.
Myopia, however, is not a "disease" of the eye that can (by itself) cause
blindness such as glaucoma or cataracts can. Rather, myopia is the visual
result in an eye (typically) that has grown "too big." Because the focusing
front part of the eye (the cornea and natural lens) don't "know" the eye is
abnormally long, they focus an image short of retina instead of right on the
retina (the "film" in the camera analogy of the eye).
