A student wanted to know last week what, exactly, 'night blindness' is. I
didn't know. Does anyone here know? Specifically, is it loss in the
ability to perceive form or is it something else? Does it occur because
people are focussing at the wrong depth in the night? (I read that this
can happen in the night when driving because of a kind of overconfidence
that motion perception gives some people.) Is it a problem at the receptor
level? If it's a problem at the receptor level, what's the problem?
Thank you.
