TESTET OG UDGIVET

Hvert linseniveau bliver benchverificeret på et spektrometer, før specifikationerne offentliggøres på webstedet. Rød holder 100 % over 570 nm i det kalibrerede blå og grønne område. Det, vi publicerer, er, hvad linsen gør. Par efter par.

KALIBRERET - IKKE TONET

Hver EMR-TEK-linse er optisk kalibreret og laboratorie-verificeret. Ikke tonet plast med en vag påstand om blåt lys. Stel er konstrueret til daglig, langvarig brug, bygget til at holde længere end de engangs-blålysblokkere, der sælges som skærmtilbehør. Hvert par fås med enkeltstyrke, forstørrelse, recept, progressive eller bifokale glas. Én verificeret standard på tværs af hele sortimentet.

ALLE PUBLISEREDE SPECIFIKATIONER

Gul blokerer 90 % af blåt lys over 400–450 nm. Orange blokerer 98 % over 400–520 nm. Rød blokerer 100 % af blåt OG grønt over 400–570 nm. Tre linsestyrker tilpasset tidspunktet på dagen, hver med sit eget offentliggjorte blokeringsområde. Hvis vi trykte tallet, opnår linsen det. Par efter par.

Frequently Asked Questions

  • Three tiers, three windows:

    • Daytime / screen use (yellow or orange lens) — for computer and phone time during the day. Cuts the high-energy blue peak without distorting colors so much you can't work.
    • Evening (orange lens) — 2–3 hours before bed. More aggressive blue block, still usable around the house.
    • Red lens (deep-night) — 1 hour before bed and into the night. Blocks blue and green. This is the strictest tier.

    Most people who go all-in own two pairs: a daytime tier and a red tier. If you're only buying one, start with the red.

  • Every lens tier gets bench-verified on a spectrometer before the spec goes live on the site. The red tier holds 100% block past 570 nm across the calibrated blue and green range. What we publish is what the lens does. Pair after pair — not one hero sample.

    The test curves are public. If you want to see them, email info@emr-tek.com and we'll send the spectrometer reports.

  • Off-the-shelf tiers (red, orange, yellow): US orders ship in 1–2 business days, 3–5 days to your door. Free shipping over $99. International ships duty-free worldwide — no surprise customs bill.

    Prescription pairs: Each pair gets individually made to your script, so shipping takes longer — typically 2–3 weeks from order to delivery.

    If the tier or fit isn't right, send them back within 30 days for a full refund. No restocking fees. Most returns are actually tier swaps (red for orange, usually) — email support before shipping back and we'll handle the exchange directly so you're not paying return shipping twice.

  • Don't drive in the red tier — color perception shifts too far for safe driving (red/green traffic lights get weird). Use the yellow or orange tier for driving at night if you need one.

    For work, the red lenses are fine for reading, talking, watching TV, or anything around the house. For color-accurate work (design, photo, video editing) use the yellow tier during the workday and switch to red when you're winding down.
