Blue Light Glasses

Blue light from screens and LED lighting peaks around 450 nm. Lenses that filter 400 to 450 nm cut the band most associated with evening alertness and screen strain while leaving most visible color intact. Clear or lightly tinted lenses filter a portion of that band for daytime work; amber and red lenses filter nearly all of it for the hours before sleep, which is what "sleep glasses" and "red lens glasses" searches refer to.

EMR-TEK publishes 400 to 450 nm filtration across the line; ask our team for the percentage blocked and lens tint on a specific frame if you need evening-strength blocking rather than daytime screen use. Blue light glasses are not a medical device and do not replace a prescription.

• Valkyrie: sleek modern frame.
• Atlas: bold full frame.
• Skoll: wraparound frame, the most coverage from side light.
• Anubis: low-profile frame.
• Athena and Freya: lighter, rounder styles.
• Ares Aviator: aviator frame.
• NYX and Apollo: everyday rectangular frames.
• Odin Magnesium: magnesium frame, the lightest and strongest in the line.

All ten are $99 with the same filtration and a 1-year warranty, so the choice is fit and style. Wraparounds (Skoll) block the most light from the sides, which matters in the evening; aviators and low-profile frames suit daytime desk use.

For screen strain during the day, wear a lighter lens whenever you are at a monitor. For sleep, put on the stronger-filtering pair 2 to 3 hours before bed and keep them on under house lights and screens. Gamers use the same lenses for long sessions. Clean with a microfiber cloth and lens spray; avoid paper towels.
