How long for eyes to adjust to darkness after being exposed to glare?

The eye's iris (the circular, colorful area around the pupil) is a muscle that contracts the pupil. In a dark environment, the pupil becomes more dilated (larger) because the iris pulls the pupil to allow more light to enter. This allows you to see in darker environments.

∙ 10y agoYour pupils open and close due to various lighting so that you limit the amount of light going into your eye (keep you from going blind), if you in a dark room and a bright light suddenly turns on your pupils will shrink so that less light can get in, but then will adjust over time so that your pupils are normal size and you can see very well... Have ever had a picture taken with flash and your vision turns blurry? Well that's your pupil trying to close up.

Polarized lenses reduce glare from reflective surfaces like snow and water, they do so by changing the angle of absorbed light and blocking out the remaining rays that reflect into the eyes.
