A lot of movies, especially horror movies (I’m watching one now) depict blind people as not having pupils. But my understanding, based on blind people I’ve met, is that the problem is usually in the lens or the retina, and that they have pupils the same as everyone else. Are there actually blind people out there whose eyes are 100% white, or is that purely a Hollywood invention?
It depends entirely on the cause of their blindness. Some people are blind due to underdeveloped/damaged optic nerves, some are blind due to brain trauma, some are blind due to an injury to the eyes, themselves, etc.
Some eye conditions can cause material to build up in the eye, causing a milky/cloudy appearance, and often lead to blindness. While this isn’t particularly common among blind folks, it’s usually the easiest to display visually, hence its overuse in film. There’s also the shock value of it, as it’s more visually interesting for the viewer than something like the actor wearing blackout glasses.
Yep. The standard Hollywood eyes are pretty close to how my dad’s look. Only Hollywood tends to do grey while his are a very pale blue. I didn’t actually learn he technically had brown eyes until I was in my late teens.
