Spectra479 Blue Light Blocking Glasses for Sleep, Wraparound

Improve your sleep with these premium Spectra479 Nighttime Blue Blockers. These are the high-quality 'Classic' model with a wraparound frame that prevents blue light from 'leaking' in through the sides—much more effective than standard flat blue-light glasses. Specifically designed to block 99.8% of the critical 450-510nm blue light spectrum that suppresses melatonin. Perfect for winding down while using your laptop, phone, or watching TV in the 1-2 hours before bed.
