The Truth About Blue Light Glasses: Do They Really Help with Eye Strain and Sleep Quality?

A new analysis of 17 randomized controlled trials suggests that blue light blocking glasses may not provide significant benefits for eye strain or sleep quality. The study found no short-term advantages in using blue-light filtering spectacle lenses compared to non-blue-light filtering lenses. It remains unclear whether these glasses affect vision quality or sleep-related outcomes, and more research is needed to assess any potential long-term effects. Experts recommend taking regular screen breaks and following the "20-20-20 rule" of looking away from screens every 20 minutes for 20 seconds to relax the eyes.
