Our optical-grade red lenses block 100% of blue and green light from 400nm to 550nm—precisely the range most associated with disrupting natural circadian rhythms and nighttime light sensitivity. This makes them ideal for evening use when winding down and preparing for rest.
Blue AND Green Light Filtering Glasses
Our scientifically designed blue and green light filtering glasses don’t just protect your eyes—they look great doing it!
Featuring our custom-designed Nocturnal Red 550 Lens, these glasses are engineered to filter 100% of light in the 380–550nm range—the wavelengths widely associated in research with potential melatonin disruption when exposed to artificial light at night.
It’s Not Just Blue... It’s Also Green...
Green light sits next to blue light on the visible spectrum. As such, the "melatonin suppression range" can extend beyond blue and into green light. Exposure to green light at night—particularly up to 550nm—may send signals to the brain that it's still daytime.
For the best evening protection, it’s important to filter both blue and green wavelengths effectively. Many standard "blue blocking" glasses do not filter the full range of light associated with nighttime disruption.
NightFall Glasses incorporate one of the most advanced light-filtering lens technologies available, specifically developed for after-dark use. They are an excellent choice for individuals seeking a comfortable visual experience in the evening while supporting natural light rhythms.
