Only available from Hammacher Schlemmer, these are the technologically advanced glasses that protect the eyes from blue light’s damaging effects. Blue light, which is emitted from the screens of electronic devices, has been linked to sleep problems and long-term vision issues including macular degeneration, cataracts, and more. Made with lightweight, durable, and flexible thermoplastic frames and polycarbonate lenses, the glasses use melanin lens technology that filters the harmful portions of blue light without loss of color perception, providing enhanced clarity when working on a computer or tablet. The risk of sleep disruption is reduced even when checking emails on a screen late at night. Can also be worn indoors without using electronic devices and for protecting against the blue light emitted by LED light bulbs.
