~ Both Sides ~

For The Claim

A 2022 observational study found a statistical association between dim-light reading and myopia in schoolchildren.
Mayo Clinic identifies reading in very dim light as a trigger for eyestrain.

Against The Claim

The National Eye Institute says dim-light reading may cause tired eyes but is not harmful.
The American Academy of Ophthalmology says reading in dim light does not harm the eyes.
Mayo Clinic says eyestrain usually resolves with rest and has no serious or long-term consequences.

Bottom Line

Dim light can reduce visual comfort and produce temporary eyestrain. The available institutional guidance does not support permanent eyesight damage; the observational myopia finding does not establish that dim light is the cause.

~ What We Couldn't Find ~

Evidence directly testing decades-long dim-light reading is limited, but major eye-health organizations consistently distinguish temporary strain from permanent damage.
