What causes one eye to look either lighter or darker than the other?
I was wondering if you could tell me why one eye might look lighter or darker than the other.
There could be a few different reasons for this. One possibility is a condition called anisocoria, which means that one pupil is larger than the other. Another possibility is that one eye is receiving more or less light than the other due to a structural issue or injury.
