Blue light blocking glasses reduce dry eye symptoms in people who use screens.

Is it true that blue light blocking glasses reduce dry eye symptoms in people who use screens?

Unclear. A 2017 systematic review of randomized trials found no evidence that blue-blocking spectacle lenses reduce eyestrain or eye fatigue, and an updated 2026 review reports that most studies find no significant difference for digital eye strain symptoms. A reference source likewise attributes screen-related eye symptoms to computer use and reduced blink rate rather than blue light, and notes the American Academy of Ophthalmology does not recommend blue-light-blocking eyewear.
