Lens Material: High-Impact Resin
Filter Category: 0 (Clear / Very Light Tint)
Luminous Transmittance (Tv): 93.39%
Note: Very high visible light transmission — ideal for all-day indoor/outdoor wear with minimal tinting or color distortion.

Blue Light Blocking Efficiency:

Tsb (380–500 nm): 25.54% Transmission
Translation: Transmits 25.54% of 380–500 nm light — blocks ~74.46% of blue light. Provides modest blue-light reduction appropriate for daily screen use without strong color shift.
Spectrum Coverage: Tmin (475–650 nm): 67.13% Transmission
Translation: Allows the majority of light in the green–red range to pass (≈67% transmission), so colour rendering and visual clarity remain largely preserved.

UV Protection:

UVA (315–380 nm): 0.07% Transmission (≈99.93% Blocked)
UVB (280–315 nm): 0.00% Transmission (100% Blocked)
UV400 Protection: Confirmed (virtually all UVA/UVB blocked).

Spectral Cut-Off Notes:

Cut-on region begins in the lower blue (~around 400–450 nm), with significant transmission rising quickly thereafter.
0–~400 nm (UV zone): Essentially no transmission.
~450 nm+ (visible safe zone): Transmittance rises to high values (overall Tv ~93%), permitting normal color perception and daylight visibility.

Summary of Lab Findings:

Blue Light Blocking (380–500 nm): ~74.5% Blocked.
Green/Red Transmission (475–650 nm): ~67% Transmission (preserves color fidelity).
UV Protection: ~100% UV protection (UV400).
Standards: Pass — ANSI Z80.3:2018, EN ISO 12312-1:2013(A1:2015), AS/NZS 1067.1:2016.

Usage Verdict: Designed for daily, all-day wear - reduces a meaningful portion of high-energy blue light while maintaining excellent visible light clarity and colour accuracy. Suitable for indoor screen work and outdoor daytime use.

Blue cut: ~75% attenuation across manufacturer‑specified short‑wavelength band.
Visible transmittance: ~95% (high clarity for TV/indoor viewing).
Lens type: optical‑grade blue‑filter lenses (anti‑reflective coating optional per SKU).
Fit: unisex frame, lightweight construction.

Usage

Wear all day for office, study, reading, and screen-intensive tasks.
For evening wind‑down, Day Sync reduces some blue light but consider switching to Night Sync 60–120 minutes before bedtime for stronger circadian protection.

Care & maintenance

Clean with included microfiber cloth and lens cleaner; store in case when not in use.
Avoid abrasive cleaners and extreme heat.

Cautions

While Day Sync preserves near‑natural colour, avoid using when driving.
Not a substitute for certified sunglasses outdoors.
If you have specific eye conditions or require workplace hearing/vision compliance, consult a 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

Yes. With a 93.39% light transmission and Filter Category 0, the lenses are designed for all-day indoor and outdoor daytime use, with minimal tint and excellent visual clarity.

Very little. Unlike strong blue-blocking lenses with a noticeable amber tint (Recoverby Night Sync), Recoverby Day Sync allows approximately 67% of the 475–650 nm range to pass through, helping maintain natural colors and clear visual perception.

Many computer glasses advertise high blocking percentages for wavelengths below 400–410 nm, while allowing much of the remaining blue spectrum through. Recoverby Day Sync blocks approximately 74.5% across the broader 380–500 nm range, while maintaining 93.39% overall light transmission—giving you meaningful blue-light reduction with clear vision and natural-looking colors.

The light-yellow tint comes from the lens filter, which selectively reduces part of the blue-light spectrum. Unlike stronger amber filters, Recoverby Day Sync is designed to keep the tint subtle, while still reducing approximately 74.5% of blue light across 380–500 nm and maintaining natural-looking colors.

Yes. The lenses provide UV400 protection, blocking approximately 99.93% of UVA and 100% of UVB.
