More than half of harsh screen blue, filtered while you work

Parts of light kept — no dimming, nobody can tell

Comfortable through a full screen day — no afternoon ache
How it works
Cheap blockers dim everything orange — that's the tell they're doing nothing useful. The Day lens cuts only the narrow band that tires your eyes, and lets the rest pass clean.

Of natural light kept
Long screen days wear your eyes down. The Day lens cuts more than half the harsh blue while 9 in 10 parts of light still get through — bright, true color. Independently lab-certified.

Wavelength by wavelength
Lower numbers mean more light blocked. The Day lens sits low in the harsh blue around 450 nm, then opens up so everything else stays bright and true.
Percent of light passing through the Day lens, lab-measured 2026.
Modern light is misaligned with human biology. Screens and devices flood your vision with blue wavelengths that fatigue the eyes, distort natural signals, and drain mental clarity during the day.

Cognitive Cost, Hidden in Plain Sight
Daytime screen use overstimulates the retina. Blue-enriched light from desktops increases eye strain and reduces contrast sensitivity, which leads to fatigue and slower focus. Our yellow lenses filter high-energy light, improve contrast, and help sustain sharp mental performance.
Circadian Drift, in Your Pocket
Phones emit short bursts of high-intensity light at close range. Even in daylight, this can confuse your brain’s timing cues and weaken focus. RedSpec day lenses smooth these signals, sharpen visual clarity, and protect your natural rhythm across screens.
Most blue-light glasses filter 10–20% of screen blue — and never [show the math.]
