Features
Sunglasses – yellow lens
Smart protection when you want to stay alert and see clearly.
The most important thing about sunglasses is not how much light is blocked, but where in the spectrum it is blocked. Not all blue light is bad: some of it keeps you awake and alert. The most harmful part is the short-wave blue 400–450 nm, which strains the eyes and disrupts the circadian rhythm.
That's why daily lenses are constructed like this:
• 400–450 nm (most harmful blue): ~98% blocked
• 400–500 nm (entire blue spectrum): ~75% blocked
• 500–570 nm (green light): only ~15% blocked
• UVA & UVB: 100% blocked
The result is a bright and natural view, with the most oppressive blue filtered out, but the green light that supports vibrancy and contrasts lets through. So the world doesn't look dark or brown, but sharp and vivid.
The lens meets official driving glasses requirements and has been tested for use in traffic.
Use: for the workday, in front of screens, to soften bright lights and for driving.
Shade: light yellow – bright, fresh and discreet.

Todella hyvät lasit!!!🔥😄🫶.
Olen kärsinyt vuosia valoherkkyydestä ja etsinyt siihen ratkaisua.
Nämä lasit ovat olleet reilusti parhaiten toimivat ja sopivat.
Käytän niitä töissä, autolla ajaessa pimeällä, kotona, kaupoissa ja yleisesti ottaen paikoissa, joissa on voimakas valaistus.
Sekä myös TV:tä katsellessa!
Erittäin vahva suositus!
Nää lasit on aivan parhaat, voin suositella kaikille. Nää lasit korvaa jopa sun lemppari arskat! 😎 Niin kävi mullekkin.
Lasit toimii kelillä kuin kelillä. Paisto arska, sataa tai on todella sumuista, näillä laseilla ei ole hätää kun ajelee.
Mikä parasta pimeällä kun ajat ei tarvitse sokaistua vastaan tulevien autojen valoja!
Koen että unen laatu on parantanut selkeästi. Ei tee mieli enää päivisin ja iltaisin olla näytön äärellä ilman näitä. Tai mennä kauppaan ja koulun halogeenien alle. Kiitos kiitos 💛✨
Lasit olivat todella positiivinen yllätys! Kevyet ja laadukkaan tuntuiset (hiukan liukasta materiaalia, joten vaati sankojen muotoilua pysyäkseen päässä, mutta sen jälkeen ovat olleet loistavat!). Maailma näyttää kirkkaammalta, tarkemmalta ja värikkäämmältä kuitenkaan häikäisemättä auringollakaan, joten nämä menee migreenikollakin aurinkolaseista! ☀️ Näen lukea paremmin tekstiäkin nyt ja puhelimen näyttö ei tee enää huonoa oloa. Olen niin tykästynyt näihin, että kroonisen migreenin vuoksi pidän niitä kauppareissuillakin päässä lievittääkseni oireita. Pystyn paremmin toimimaan näiden myötä, joten iso kiitos loistavista tuotteistanne! ❤️
Teinin aktiivikäytössä olleet ja päänsärkyä ollut nyt vähemmän. Malli ei ihan täysin miellytä, pienempää/kapeampaa ja sirompaa mallia voisi kuulemma pitää muidenkin nähden mutta nämä kelpuutettu kotikäyttöön.
Kajot ekaa kertaa testissä. Mukavat päässä. Itselle olivat reilun oloiset, mutta sitten sain tietää, että näitähän voi itse muokata omaan päähän sopivaksi. Ei valu nenällä ja istuu suorassa. Päädyin pitämään tämän mallin. Harkitsen jo pojilleni pelilaseja, he viettävät loppujen lopuksi paljon aikaa pelikoneidensa äärellä. Heille sitten pikkukajot.
Kyllä nyt Kommon kelpaa kokkailla !
Päänsärytkin ovat säännöllisellä käytöllä vähentyneet !!🥰
Ilmatkin vaihdelleet mustasta räpäskästä puhtaan valkoiseen , mutta lasit tuovat kirkkautta ja kontrastia .
Mielenkiinnolla odotan kun pääsee pilkkijäille testaamaan !
KOMMO SUOSITTELEE ! 🥰 😎
Oon ollut todella yllättyny näiden lasien monipuolisesta käyttömahdollisuudesta. Ehdoton tietysti näyttöjen päivittäisessä katselussa, mutta loistavat niin urheillessa kuin autoilleissakin. Ajelen pitkiä matkoja paljon ja nää lasit on ollu todella mukavat joka sään lasit. Keltainen linssi kaiken lisäksi tarkentaa näkymää, joka etenkin autoillessa tietysti erittäin loistava ominaisuus.
Keltaisissa linsseissä on jännä, tarkentava fiilis. Lasit on loistavat sporttaillessa. Mm. pyöräilyssä ja suppailussa. Eläkkeellä oleva ahtaaja on tyytyväinen näistä laseista. Olisi ollut oiva apu satamassakin työkoneiden ratissa.
Päivälasit ovat tyylikkäät, istuvat hyvin ja ovat erittäin monikäyttöiset. Erinomaiset ajolaseina eikä silmät väsy pitkälläkään matkalla. Voin käyttää aurinkolaseina ja itselle toimii todella hyvin kiekonammunnassa. Teen paljon töitä tietokoneella ja puhelimella, joten minulle on tärkeää, että voin lasien avulla ehkäistä sinivaloaltistusta. 100% tyytyväinen näihin laseihin. Iso suositus!
Erinomaiset päivälasit. Päänsärky helpottaa, tai et enää kärsi siitä. Ajaessa pimeällä todella hhvät. Kirkkaat värit paista silmään ja kontrastit paranee.
Nämä päivälasit ovat rauhoittaneet aistikuormitustani ja jotenkin kaikki näyttää selkeämmältä. Kirkkaat valot töissä, julkisilla paikoilla ja kotona ovat nyt enemmän harmoniassa. Suosittelen kaikille päivälaseja kaikille :)
Las gafas son geniales. Tenía muchos dolores de ojos y cabeza con el ordenador y desde que las uso han desaparecido, estoy muy contenta. Las recomiendo sin dudarlo.
Ostin lasit miehelle jolla on vaikeuksia nähdä autolla ajaessa haastavissa oloissa = hämärässä ja vesisateessa. Alun vastustelun jälkeen sanoi, että kyllä nää vähän tuntuis auttavan :o)) Kaivoi itse lasit esille seuraavalle automatkalle.
Hyvät on !!
Käytän laseja nyt joka päivä ajaessani autoa työmatkoilla. Rauhoittaa silmiä kivasti kun vastaantulevien autojen LED-valot ei enää häikäise samalla tavalla.
Muuten ihan ok ja käytössä hyvät. Ainoa harmillenen juttu oli lasien leveällä olevat sangat. Eli putoavat helpolla jos siirtää katseen alas. Mallikin oli jopa perheen nuorten miekestä hyvän näköinen.
Poikani 12v. käyttää laseja pelatessaan. Ei halua enää olla ruudulla ollenkaan ilman niitä. Kysyin, että huomaako eron, hän vastasi ettö todellakin huomaa!
Lasit auttavat rentoutumaan. Aluksi tuntui oudolta koska kaikki muuttuu keltaisemmalsi. Tähän tottuu kuitenkin nopeasti. Lasit ovat kevyet ja miellyttävän tuntuiset.
Malli on omiin kasvoihin leveä ja sangat tuntuivat aika jäykiltä. Päivälasit kirkastavat kyllä näkymää, mutta omille silmille tarvitsen enemmän suojaa valolta ainakin näin kesäaikaan. Iltalasien oranssi olisi varmaan ollut parempi vaihtoehto.
Keltaisten linssien ominaisuudet yllätti todella positiivisesti! Olen aikaisemmin ihmetellyt rallikuskien buumia keltaisten ajolasien käyttöön. En ihmettele enää! Lasit ovat todella mukavat autoillessa. Näkymä on joka säällä selkeämpi kuin ilman laseja.

What is blue light?
Blue light refers to light with a wavelength of approximately 400–500 nanometers. It is part of the visible light spectrum and is present in sunlight. Blue light is also found in artificial sources such as LED lights, digital devices, and display screens. Blue light has both benefits and drawbacks.
Benefits of natural blue light from the sun
Alertness and vigilance: Blue light can improve alertness and concentration. It has been used in workplaces, for example, to increase productivity.
Mood improvement: Blue light has positive effects on mood enhancement and alleviating seasonal affective disorder, especially during the winter months.
Biological rhythm: Blue light affects the body's internal clock and can help regulate sleep patterns, especially during the day.
Disadvantages of artificial blue light:
1. Sleep difficulties
Disruption of melatonin production: Blue light inhibits the production of melatonin, a hormone that regulates sleep patterns. Exposure to blue light late in the evening or at night can make it difficult to fall asleep and reduce sleep quality. This can lead to insomnia and fatigue the next day.
Disruption of the internal clock: Prolonged exposure to blue light can disrupt the body's internal clock, which can cause problems with sleep and wakefulness.
2. Eye damage
Retinal damage: Blue light, especially its shorter wavelengths (e.g., from LED lights and display screens), can cause retinal damage. Prolonged exposure can lead to the development of "blue light ischemia," which can increase the risk of eye diseases such as cataracts or macular degeneration.
Digital eye strain: Prolonged viewing of screens can lead to digital eye strain, which includes symptoms such as eye fatigue, dryness, redness, and discomfort. This can be caused by glare from blue light.
3. Headaches
Migraine: For some people, intense blue light can trigger migraine attacks or cause headaches. This may be due to light interference or tension in the eyes caused by blue light.
Stress and anxiety: Excessive exposure to blue light can lead to increased stress and anxiety, which in turn can increase the incidence of headaches.
4. Impact on mood
Behavioral symptoms: Although blue light can have positive effects on mood during the day, excessive exposure in the evenings can cause mood swings and increase anxiety or depression. This may be due to reduced sleep quality and its impact on daily well-being.
5. Skin symptoms
Skin inflammation: Newer studies suggest that blue light can affect the skin and cause inflammatory reactions, which can lead to rashes or worsening acne.
Day or night glasses?
If you want to take optimal care of your well-being and blue light prevention, we definitely recommend choosing both day and night glasses.
For blue light prevention, an orange lens used during the day might be a bit too effective as a blue light blocker. Therefore, we recommend using a yellow lens during the day, which prevents 84% of all harmful blue light.
If, on the other hand, the most important reason for using blue light glasses is to improve sleep quality and optimize your circadian rhythm, then we recommend using an orange lens in the evening. The orange lens blocks 97% of all harmful blue light and significantly helps the body achieve better and higher quality sleep.
If you want to start with only one pair of glasses and need blue light protection both during the day and in the evening, then we recommend choosing day glasses with a yellow lens. You can use the glasses from morning to evening, and as a shift worker, also during night shifts. Although the blue light protective effect of the yellow lens for evening use is not as effective as that of the orange lens, the high-quality 84% blue light protection of day glasses in the evening is still a significant aid towards better sleep.
For hobbies, as an accessory, when driving, for sunglasses, and in other activities, you can use yellow and orange lenses entirely according to your own preferences! Through both lenses, the world looks wonderfully bright and clear! And a small word of warning, you might get addicted to the view these lenses produce and no longer feel like looking at grey landscapes!

I wear prescription glasses; how can I protect my eyes from the harmful effects of blue light?
