Does reading in dim light damage your eyesight?
The human eye possesses a remarkable capacity to adjust to different lighting environments, thanks to its automatic adaptation mechanism. Pupils can expand in low light to permit more light to enter and contract in bright light to safeguard the retina. Although reading in dim light may be uncomfortable, it does not impede the eye's natural ability to acclimate to varying light levels.
While reading in low light does not inflict permanent harm on your eyes, it is still vital to ensure proper lighting conditions to prevent eye strain and discomfort. Adequate lighting enhances the reading experience and reduces the risk of fatigue. If you frequently find yourself in poorly lit settings, employing a reading light or increasing the ambient illumination can make reading more pleasant and decrease the likelihood of temporary eye strain.
