What happens to eyes if do a long study

Answer 1

When the eye adjusts to lower levels of light, many reversible things happen. Muscles around the iris relax and allow the pupil to dilate so that more light will enter and hit the back of the eye. ... However, reading or focusing on close objects in the dark can put strain on the eyes.

Answer 2
