Lens Material: Resin Filter Category: 1 (Light Tint / Daytime Use)
Luminous Transmittance (Tv): 50.67%
Note: Moderate visible light transmission — suitable for daytime wear with noticeable tint but preserved overall visibility.

Blue Light Blocking Efficiency:

Tsb (380–500 nm): 1.70% Transmission
Translation: Blocks ~98.3% of 380–500 nm blue light (very strong blue attenuation while retaining moderate visible brightness).

Spectrum Coverage:

Tmin (475–650 nm): 0.49% Transmission
Translation: Near-total attenuation across the critical blue-to-green transition into lower green wavelengths — preserves only longer wavelengths, producing a strong yellow/amber appearance.

UV Protection:

UVA (315–380 nm): 0.06% Transmission (≈99.94% Blocked)
UVB (280–315 nm): 0.00% Transmission (100% Blocked)
UV400 Protection: Confirmed (virtually all UVA/UVB blocked).

Spectral Cut-Off Notes:

Sharp cut-on occurs around ~500–560 nm with transmittance rising steeply into the amber/red region on the spectrum graph.
280–~500 nm (UV + Violet + Blue + lower green): Essentially blocked.
~550 nm (amber/red): Transmission rises, allowing color and contrast from longer wavelengths.

Summary of Lab Findings:

Blue Light Blocking (380–500 nm): ~98.3% Blocked (high).
Green/Red Transmission (475–650 nm): ~0.5% Transmission.
UV Protection: ~100%.

Standards Results:

ANSI Z80.3:2018 – FAILED (Not certified as sunglasses);
EN ISO 12312-1 & AS/NZS 1067.1 – FAILED (Not suitable for driving)
overall filter category = 1 (passes Tv range for category).

Usage Verdict:

Highly effective at blocking blue and lower-green wavelengths — suitable for strong daytime blue-blocking (screen use and daytime light sensitivity). Not suitable for driving in twilight/night or situations requiring accurate color rendering; fails several color-limit criteria and is not approved for driving in low-light conditions.

Blue cut: ~98.5% attenuation across the specified short‑wavelength band.
Visible transmittance: ~50% (balanced for low‑light evening activities and TV viewing).
Lens type: deep amber/red optical‑grade filters with anti‑reflective coating.
Fit: unisex frame, lightweight.

Usage

Recommended: wear 60–120 minutes before bedtime while exposed to screens or bright indoor lighting; remove when going to sleep.
Trial plan: use for 7 nights while tracking sleep onset and quality to evaluate personal benefit.

Care & maintenance

Clean with microfiber cloth and lens cleaner; store in case.
Avoid high heat, abrasive cleaners, and prolonged outdoor use.

Cautions

Not recommended for driving; deep tints can alter color perception of traffic signals and signage.
Not a replacement for sunglasses outdoors unless UV protection is explicitly stated.
If you have persistent sleep or eye issues, consult a healthcare professional.

CIRCADIAN RHYTHM CONTROL

Lenses shift the spectral mix reaching the retina, cutting high‑energy wavelengths that drive alertness. This reduces physiological signals that delay sleep and lowers visual contrast and glare that cause digital eye strain. The red lens strongly filters blue and adjacent green light for maximal evening circadian protection—wear before bed to ease wind‑down and speed sleep onset; not suitable for driving or tasks needing accurate color

NIGHT-TIME BIOLOGICAL RESET

After dark, artificial blue and nearby green light keeps the brain in daytime mode, delaying melatonin, increasing evening arousal, slowing wind‑down, and fragmenting sleep when exposure is repeated.

Recoverby red lenses aggressively filter those alerting bands while passing warm tones to encourage earlier melatonin release, lower cortical arousal, and faster, more stable sleep onset

PEOPLE ARE ASKING

You wear them in the evening or during late screen time to filter blue light from devices and bright indoor lighting. That can help you ease into a calmer night routine and support better sleep habits.

The amber appearance is a direct result of the lens filter. The lens strongly reduces transmission of shorter wavelengths, particularly blue light, while allowing more of the longer amber and red wavelengths to pass through. This creates the characteristic yellow/amber appearance.

Yes. The lenses are classified as Filter Category 1, intended for light-tinted daytime use. Their approximately 50.67% luminous transmittance provides noticeable tint while retaining moderate overall visible-light transmission.

Yes. Because the lenses significantly reduce blue and shorter visible wavelengths, they change color perception and produce a strong amber/yellow visual effect. They are therefore not intended for situations where accurate color rendering is important.

Many computer glasses focus on wavelengths below 400–410 nm and may block high percentages within that narrower range. Our Blue Light Recoverby lenses go further, blocking approximately 98.3% across the much broader 380–500 nm range—providing strong attenuation throughout the blue-light spectrum, not just below 400 nm.
