Application Guide

Application Guide: When to Use & When Not to

Helping you choose the right glass type for your specific application — avoiding costly mismatches.

Ideal Applications

Extended Screen-Time Workstations
Filters 30-50% of harmful 380-450nm blue light while maintaining >85% visible light transmission
Bedroom & Evening-Use Displays
Reduces blue light exposure before sleep, supports circadian rhythm without significantly altering display colors
Children's Educational Devices
Eye-protection glass for tablets and learning machines, physical filtration (no coating to wear off)
Gaming Monitor Covers
Long gaming sessions with reduced eye strain, maintains color accuracy for non-blue color channels
Reading Lamps & Task Lights
Warm-tone glass filter for LED light covers, reduces harsh blue spike in white LED spectra

Not Recommended For

Color-Critical Design Work
Blue-light filtering alters color temperature; for graphic design/print proofing, use neutral clear AR glass
Outdoor Full-Color Signage
Blue light filtering reduces color gamut and makes displays appear yellowish; use standard clear glass
UV-Curing & Sterilization
This glass filters blue light; UV applications need separate UV-transmitting or UV-blocking glass
