How Eye Reacts Under Low Light

The eyes adjust to the amount of light in the surroundings. When the light in the room is decreased, the pupils are expanded to allow more light to enter the retina at the back of the eye in an effort to keep vision open and functional under less than ideal conditions.
Low-light reading habits decrease the eyes ' ability to focus clearly, causing them to get tired. Under low light, many people also blink less frequently, which can cause temporary eye dryness.
