Is it true that reading in the dark can cause nearsightedness? Here are the facts.

Medical consensus indicates that reading in dark or low-light conditions does not directly cause myopia, commonly known as nearsightedness, or permanently damage the eyes.

While low-light reading does not alter the physical structure of the eye to induce a minus prescription, it can lead to temporary eye strain, fatigue, and discomfort due to the increased effort required by the eye muscles to focus.
