These are the technologically advanced reading glasses that protect the eyes from harmful blue light when reading or doing close work. Blue light, which is emitted from the screens of electronic devices, has been linked to sleep problems and issues including macular degeneration, cataracts, and more. Crafted with durable, lightweight frames, the melanin-infused lenses filter the harmful portions of blue light while simultaneously blocking 99% of glare. There’s no distortion or loss of color perception; the eyes also experience less fatigue and stress for a more comfortable reading experience. The risk of sleep disruption is reduced even when checking email on a device late at night. Available in diopter power 1.5, 2.0, 2.5, and 3.0.
