These are clip-on lenses that attach to the frames you already wear and filter the blue light given off by phones, laptops, tablets and LED bulbs in the evening. The clip-on format is the main draw: you keep your prescription glasses on and add the filter only for screen time before bed. They are aimed at people who read or work on screens late and want to cut blue light exposure without buying a second pair of glasses. The idea that filtering blue light improves sleep is plausible but the evidence is modest, so treat the sleep claims as a nudge toward better evening habits rather than a cure.

Buyers rate these highly and mostly talk about easier evenings on screens and a more relaxed wind-down. Complaints center on fit and the extra bulk on the nose.
