Teravan Somnus I Blue and Green Wavelength Blocking OTG Fitover Glasses

Teravan Somnus I 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.
Teravan Somnus I glasses use a unique lens technology that provides over 25% light transmittance for better visibility than regular blue light blocking glasses.
Teravan Somnus I glasses offer you a convenient way to reduce your blue light exposure that can cause eyestrain, headaches, and eye fatigue from staring at your computer, phone, laptop and TV at night.
Comfortably made for both men and women. It is designed to fit over regular-sized glasses or just by itself. Extra width for increased comfort while maintaining enhanced eye coverage with top, bottom, and side block. Quality nylon lenses are supported by a flexible and strong polycarbonate frame.
Individual results may vary. We recommend using them for between 30 minutes to 2 hours before bed time.
