if my pupils dilate in the dark to let in more light in order to see more; why isn’t it really bright when they dilate while drunk?
In: Biology
Much of the seeing-in-the-dark effect is not due to pupil dilation but to an increase in your eye’s sensitivity to light. Your pupils can contract and dilate very quickly, like in a second or less, but the chemical adaptation takes up to twenty minutes to kick in fully, and several seconds to wear off in bright light.
