Blindness is a symptom, not a condition.
So I have a rant.
I’ve noticed, with a lot of blind fictional characters, the writers just say they were ‘blind from birth’ which is such a copout. It’s like saying that your nose is running. No reason given- could be allergies, could be a cold, could be that you ate something super spicy.
Eye conditions that cause blindness and visual impairment (only something like 8 percent of legally blind people are completely blind) are varied and they have different effects and other symptoms. Not everyone who is blind ‘looks blind’ or has the clouded cornea that traditionally signals that a character is blind. The problem can be in the front of the eye, but it can also be in the optic nerves or the brain.
Your character could have Albinism, Optic Nerve Hypoplasia, Retinopathy of Prematurity , Cataracts, Corneal Disease, Glaucoma, Diabetic Retinopathy, Macular degeneration, a detached retina, I’m sure I’m missing some. Each of these things affects the eye differently, and come with other symptoms.
Blind representation is so important, but so is doing some research as to why. This isn’t just a problem with OCs or fanfiction, this is a problem I see with canon blind characters and it’s so frustrating.
