Can severe myopia cause blindness?
Once it’s in the -5/beyond range, you’re at a much greater risk of experiencing a retinal detachment, which can lead to blindness if not properly identified and treated in a timely fashion. The best thing you can do to prevent irreversible vision loss is KNOWING the signs- seeing flashes of light, experiencing a sudden and rapid increase in the incidence of floaters, a feeling of slight heaviness in the eye, or later, a dense shadow over your outer vision. If you experience those symptoms, call your ophthalmologist or a retinal specialist at the first possible moment, or go to a hospital.
