Can reading in dim light damage your eyesight?

Reading in dim light can cause eye strain, but it's not likely to cause permanent damage to your eyesight. When you read in low light, your eyes work harder to focus, which can cause fatigue and eye strain. This can lead to headaches, dry eyes, and blurry vision.

While reading in dim light can cause discomfort, it won't cause any long-term harm to your eyes. However, it's still a good idea to avoid reading in low light if possible. If you do need to read in dim light, try to use a reading light or increase the font size on your device to reduce eye strain.
