Alex (Day)

Alex (Day) is a premium daytime blue light blocking glasses design that brings a subtle, familiar frame together with a smart pop of color. The clear or lightly tinted lenses filter harmful artificial blue light from screens and modern LED lighting while maintaining natural color perception, so you can stay visually clear and comfortable during the day. Available in Non-Prescription, Readers, and Prescription options, Alex (Day) supports a nature-first approach to wellbeing—helping you move toward full spectrum living without sacrificing style or clarity.

This is the Day version: engineered for daytime blue light filtering to reduce visual strain and help protect your circadian rhythm from the constant artificial light of indoor life. The Night version (sold separately) is designed for evening use with stronger blue light reduction to support sleep and melatonin production.

• Daytime blue light filtering: reduces harmful artificial blue light from screens and LED lighting while preserving natural color perception.

Independently lab-tested: 100% of the blue light hazard range blocked, 80% visible light preserved
