Can you tell that someone is blind by looking at their eyes long enough?

Question

Can you?

Also, what forms of blindness are easy to spot?

Answer 1

Well, I'm blind in one of my eyes and I don't think people would be able to tell I'm actually blind in that eye. Everyone just assumes I have a lazy eye, because it turns out a little bit.  I'm sure you would be able to tell someone was blind if you looked really carefully at them, maybe noticing that their eyes dont move or twitch like a normal eye would.

Answer 2

Blind people usually don't look at you in the eye when they talk to you.

Severe corneal scarring is easy to spot - the surface of the eye is all milky. Also severe ocular trauma is pretty obvious. Otherwise most types of blindness are not obviously visible externally.

Answer 3

Someone particularly detailed in their observations would note that my pupils are sluggish to react, but cosmetically, my eyes both look 100% normal- a casual observer would not be able to tell at all.

Answer 4

Some forms can be seen.

Lack of eye movement,

pupils unresponsive to changes in light,

the clouding of the lens by cataracts,

lack of eye movement,

are observable sympotoms.
