Our signature Sleep+ red lens is the world's most advanced blue and green light blocker. Blocking 100% of blue and green light from 400-550nm, our Sleep+ lens is the optimal blue blocker for after dark. When worn 2 – 3 hours before bed, the advanced lens technology induces the ‘camping effect’ allowing the body to produce melatonin (the sleep hormone) which is otherwise prohibited when blue & green light it present. The results are improved sleep and health after just one use, leaving you feeling refreshed and energised from a proper night’s sleep. These glasses also make a great companion when travelling, aiding with the management of jet lag and re-aligning your body clock. *All our glasses are unisex and come in Prescription, Non-Prescription, and Readers.
