No direct evidence found that reading in dim light causes permanent eye damage, though it may cause temporary eye strain.
The provided abstracts do not contain any studies that directly examine whether reading in dim light damages eyesight. While research shows that electronic devices can affect tear film stability and cause eye strain symptoms compared to printed materials, there is no evidence of permanent structural damage to the eyes from reading in low light conditions.
Caveats
The abstracts provided focus on reading aids, eye diseases, and digital vs. print reading, but none directly study the effects of dim lighting on eye health. More targeted research is needed.
