Why do blue light glasses turn your screen yellow?

Yellow tinting happens when lenses use heavy surface coatings or amber-tinted materials that block broad-spectrum light. CLÆR SPECTRUM™ lenses use an embedded filtration process that targets only the 400–450nm blue-violet range, leaving the rest of the visible spectrum intact — so colours look accurate and lenses appear clear on screen.

What is the difference between a surface coating and an embedded lens filter?

A surface coating sits on top of the lens and can scratch, peel, and fade over time. An embedded filter — like CLÆR SPECTRUM™ — is built into the optical material itself during manufacturing. Nothing to wear off. The filtration is permanent for the life of the lens.

What does ~55% blue-violet filtration at 400–450nm mean?

It means CLÆR SPECTRUM™ lenses block an average of ~55% of light in the 400–450nm wavelength range — the high-energy blue-violet band most associated with digital eye discomfort. The filtration is strongest at 400nm and tapers deliberately through to 450nm, which protects colour accuracy for screen-based work.

What is SHMC coating on glasses?

SHMC stands for Super Hydrophobic Multi-layer Coating. It is a premium optical surface treatment that reduces glare, repels water and oil, resists scratches, and makes lenses easier to clean. All CLÆR SPECTRUM™ lenses include SHMC coating as standard.

What is UV400 protection?

UV400 means the lenses block all ultraviolet light up to 400 nanometres — covering both UVA and UVB rays. This is the highest level of UV protection available in eyewear. CLÆR lenses show 0.00% UVA/UVB transmittance, independently tested.

Are CLÆR SPECTRUM™ lenses independently tested?

Yes. CLÆR SPECTRUM™ lenses are independently tested to ISO 12312-1:2022 and ANSI Z80.3-2018. The full spectral transmittance curve (380–780nm) is published directly on this page — plotted from raw lab data at 5nm intervals, not estimated or cherry-picked.

Do the lenses have a tint?

There is a very subtle tint. If you hold the lenses up to a white wall you may notice a slight shift — that is physics, it happens with any lens genuinely filtering blue-violet light at this level. On a screen, which is what they are designed for, the lenses read completely clear with no yellow tint and no interference with colour accuracy.

01 — THE PROBLEM

You've already tried a cheap pair. It either did nothing, or it turned your screen yellow.

Most blue-light glasses are a coin flip — coatings that fade, or filters strong enough to wreck your colour work. We measured ours so you don't have to guess.

02 — THE MECHANISM

THE FILTER IS BUILT INTO THE LENS. NOT PAINTED ON TOP OF IT.

Most blue-light lenses apply a surface coating — a thin layer that scratches, peels, and fades. CLÆR SPECTRUM™ is engineered into the optical material itself during manufacturing. Nothing to wear off.

03 — THE LENS

The CLÆR SPECTRUM™ Lens

Japanese optical-grade material, engineered for screens, tested to international standards.

SURFACE TREATMENT

SHMC

Multi-layer anti-reflective coating. Cuts glare, resists smudges, protects the lens surface.

BLUE-VIOLET FILTERED

~55%

Average filtration across the 400–450nm range, strongest right where it starts.

LENS MATERIAL

Japanese

Optical-grade material with the filter engineered through it, not coated on top.

UV PROTECTION

UV400

0.00% UVA/UVB transmittance, independently tested.

380nm 400–450nm filtered 780nm

Tested to ISO 12312-1 and ANSI Z80.3. Not estimated.

04 — THE PROOF

THIS IS THE ACTUAL LENS. TESTED, NOT ESTIMATED.

Shaded area = transmittance suppressed below baseline. Real curve, plotted from raw lab data at 5nm intervals.

WHY THE CURVE, NOT A SINGLE NUMBER

Most brands quote one wavelength. We're showing the full 380–780nm range so you can see exactly where filtration happens — and where it doesn't.

ENGINEERED TAPER, NOT A HARD CUT

The curve climbs deliberately from 400nm to 450nm — strongest at the harshest wavelength, easing off exactly where colour accuracy matters.

VERIFIED, NOT MARKETING COPY

Every value on this chart comes directly from an independent lab report — not an internal estimate.

06 — WHAT THIS MEANS

WHERE IT MATTERS MOST

Strongest filtration sits right at 400nm — the deepest, harshest blue-violet wavelength.

ENGINEERED, NOT ACCIDENTAL

The filter is precisely tuned to ease off through 420–450nm — exactly the curve real colour work needs.

TRUE COLOUR, UNTOUCHED

Past 460nm, visible light passes through clean — nothing tinted, nothing distorted.
