The blocking-performance pick under $70 — the only one here publishing separate blue AND green figures with wavelength bands.
Where most brands round to "99% of blue light", SafetyBlue publishes the bands: 99.9% across 450-495nm (blue), 99.7% across 495-570nm (green), and full UV to 280-400nm. Green matters because the melanopic response that shifts your body clock peaks near 480nm and extends past 500nm — a lens stopping at 500nm leaves part of it through. It's a wraparound with optional foam gaskets that seal the gap around the frame, the failure mode nobody else addresses. It is also, by the brand's own admission, unwearable for driving.

Should you buy it?
What we like
- Per-band figures with wavelength ranges, not a rounded headline number
- Covers green light to 570nm — wider than Swanwick or Spectra479
- Foam gaskets available to close peripheral light leak
- Fits over most prescription frames
What to know before buying
- Colour distortion the brand itself calls severe — driving is prohibited
- No spectral transmission chart, so the precise figures can't be verified
- Gaskets — the part that makes the seal work — cost extra
- Wraparound sport styling won't suit everyone

Frequently asked questions
Why does blocking green light matter?
The receptor that signals "daytime" to your body clock responds most strongly around 480nm and stays sensitive past 500nm. A lens that stops at 500nm — which several popular amber lenses do — leaves part of that range through. SafetyBlue's 570nm ceiling covers it; that's the concrete reason to prefer a red lens over amber.
Can I drive in them?
No, and the brand says so directly. Colour distortion is severe enough that traffic lights and brake lights are unreliable. These are for the last hours indoors before bed, not for going out.
Are the foam gaskets worth it?
They're the difference between a tinted lens and an actual light seal — without them, light reaches your eyes around the frame edge. They cost extra, which is a fair criticism at $59.95, but they address a gap most competitors ignore entirely.
Does SafetyBlue prove the melatonin claims?
No. The brand states its red lenses "enhance your body's melatonin production" but publishes no study supporting it. Treat the blocking percentages as the product's real claim and the melatonin framing as marketing.
