red lenses glasses block close to 100% of both blue and green wavelengths. While many glasses block only blue light, recent studies have shown that lower wavelengths also have a significant effect on sleep patterns. We block all wavelengths below 550 nm, which includes blue, green and violet. PERFECT FOR TRAVELERS & SHIFT WORKERS: Work at night and sleep throughout the day? Sleep Savior glasses will give you quality day-time sleep. Put an end to jet lag and sleep through your flights. Orange lenses significantly reduce glare and block blue light more than other lenses, and are especially designed for night time viewing of digital screens. The orange tint reduces the contrast from bright screens in dark settings, allowing you to sleep better. Tinted lenses minimize digital eyestrain caused by harmful blue light (HEV light) emitted from computer screens, mobile phones, TVs, and other digital monitors. Studies show continued exposure to Blue Light damages your retinal cells and prematurely age’s your eye tissue. Sleep ZM lenses protect your eyes with UV 400 technology normally found in sunglasses.
