SleepAid Orange Merritt Blue Light Glasses – Blue
Part of the SleepAid Orange lens collection
Browsing on your phone before bed, or working late at the computer? Evening light — especially the blue and green part of the spectrum — is the part that keeps your body alert when you'd rather be winding down.
The SleepAid Orange lens blocks 99% of light between 380 and 550nm. That figure is measured by Micro-Light Optics against ISO 12312-1 and ANSI Z80.3, and published in full on our science page, along with what the research does and doesn't show.
The Merritt square frame in translucent blue, with orange lenses for the last hours of the evening. Category 1 filter, 48.2% visible light transmission — dark enough to do its job, light enough to keep watching TV, reading or scrolling as normal.
Not for night driving. At 48.2% visible light transmission, this lens is well under the 75% minimum required after dark.
