Is there scientific research supporting the use of blue light blocking glasses?Updated 3 months ago

Yes. Multiple peer-reviewed studies support the role of blue-blocking eyewear in sleep and circadian health, particularly for evening use. Research in publications such as Translational Vision Science & Technology, Frontiers in Neurology, and PubMed-indexed journals shows that appropriately calibrated blue-blocking lenses — those with sufficient melanopic attenuation — can improve sleep onset, sleep quality, and circadian alignment. TrueDark’s lenses are engineered to meet the filtering thresholds shown to be clinically meaningful, unlike many generic blue light coatings.
