Blue Light Guide

Blue light products, explained

NoBlue uses separate product categories for different use cases. The main differences are lens or filter type, visible tint, time of day and device compatibility.

Daytime glasses

Daytime blue light glasses use a lighter visible tint and are designed for work, study and general screen routines during the day.

Evening glasses

Evening blue light glasses use visibly orange lenses for screens and artificial light after dark. If you want both systems, see Day + Evening sets.

Screen filters and privacy filters

If you prefer a display-level option, screen filters include blue light filters and privacy filters. Fit depends on visible screen width, height and aspect ratio, not only diagonal size.

Lighting

NoBlue lighting includes bulbs, cordless lamps and an LED strip for warmer evening illumination.

Measured optical performance

For Day and Evening lens data, see NoBlue Test Results. The page presents published spectral transmission measurements and source details. Optical measurements describe product transmission and do not guarantee a specific health outcome.
