SleepAidMax Red Merritt Blue Light Glasses – Crystal
Part of the SleepAidMax Red lens collection
The Merritt in a translucent crystal frame, fitted with our strongest evening lens.
Independently lab-tested by Micro-Light Optics, the SleepAidMax red lens filters 99.7% across 380–580nm at 22.2% visible light transmission — Category 2 under ISO 12312-1. That covers blue light and the green wavelengths beside it, so colors shift heavily warm. It's a lens for the last two to three hours before bed, not the working day. Not a lens for driving.
Full measured data for all fourteen of our lenses is on our science page, including what the research does and doesn't support.
A fraction of the price.
Light sensitivity buyers shopping the premium brands rarely realize there's an affordable, lab-certified alternative. Here's the math.
