The blue light emitting from your screen as you read this has become a bit of a bogeyman, allegedly responsible for eye strain, headaches, poor sleep and much more. Enter blue light-blocking glasses, also called blue light glasses or blue light-filtering glasses. Advocates of blue light glasses claim these lenses can absorb or filter the short wavelengths of blue light produced by our devices, which in turn improves sleep, vision and even focus and productivity. In this episode, we explore blue light and whether specialized eyewear is the answer to its possible harms.
