These are the world\'s most advanced blue and green light blocking lenses designed for after-dark use. They block 99% of blue and green light from 380-570nm making it the most powerful lens on the market. We have wrapped our Nocturnal lens in a high quality light frame with a wrap-around fit to minimise leakage of unfiltered light, and high quality design to ensure a comfortable fit. These blue blocker glasses are made for people who are serious about improving their sleep and want the best possible product to do the job! You can still see to read, watch TV or work on your computer/tablet/phone, while your sleep hormones shift to night mode. To ensure you have both day AND night protection we recommend you also use a set of our ScreenTime FITOVER daytime glasses during the day.
