Blue light blocking glasses claim to reduce eye strain and improve sleep, but there’s no evidence to support these claims. If you experience digital eye strain, it’s more likely due to staring at the screen up close for hours at a time. To reduce eye strain, try to look at something at least 20 feet away for 20 seconds or longer for every 20 minutes of screen time.

Blue-light filtering glasses may not reduce eyestrain associated with computer use, and their effect on improving sleep quality and retinal health is unclear, a review published Thursday says.

An analysis of previous trials suggests blue-light-filtering lenses may not reduce eyestrain or sleep problems

WEDNESDAY, Aug. 23, 2023 (HealthDay News) -- Blue-light filtering lenses, which filter ultraviolet radiation and claim to improve visual performance with digital device use, seem not to attenuate symptoms of

Despite claims by their makers, blue light glasses probably dont reduce eyestrain for people who spend a lot of time looking at computer screens or phones.

Adding a blue-light filter to your eyeglasses may not ease eye strain from computer work, protect the retina or help with sleep at night, according to a new review of

According to an analysis of 17 randomized controlled studies, blue light-blocking eyewear has no effect on computer-related eye strain or sleep quality.

The included studies did not examine this outcome, hence the study found no evidence that blue-light-filtering lenses protect the retina, the light-sensitive tissue at the back of the eye.

Spectacles that are marketed to filter out blue light probably make no difference to sleep quality, according to a new Cochrane review.
