Blue Light Filtering Glasses: Effects on Sleep, Visual Performance, and Eye Health
Do Blue Light Filtering Glasses Actually Improve Sleep and Protect Your Eyes?
Blue light filtering glasses show mixed results for sleep improvement and limited evidence for eye protection, with research revealing modest benefits for some individuals but not the dramatic effects often claimed by manufacturers. Studies demonstrate that blue light glasses may slightly improve sleep quality in people with high evening screen exposure, but the effects are generally smaller than simply reducing screen time or using device-based blue light filters. For eye health, current evidence does not support claims that blue light glasses prevent macular degeneration or significant eye damage from normal screen use.
