Customer Reviews
Overall rating: 4.6 / 5 from 45 reviews.
Istuvuus hyvä, mukavan pehmoset vasten kasvoja, ei purista, mukautuu ja vielä näyttääkin hyvältä, niin jee!
Hankittiin miehen kanssa lasit samaan aikaan ja ne ovat olleet joka ilta käytössä sen jälkeen! Koko päivän kun istuu töissä näyttöpäätteen edessä niin nämä lasit rauhoittavat silmiä mukavasti iltaisin.
Tämä lamppu on oikein hyvä ja toimii rauhoittavasti.
Kyllä 16-vuotiaskin alkaa laseja käyttämään kun hyvin perustelee miksi niitä pitää käyttää! Nämä iltaisin päässä kun katsotaan telkkaria tai pelataan😊
Näiden sangat oli vähän löysät ja leveät, joten eivät istu jämäkästi päähän. Ne levenevät korvia kohti. Täytyy käyttää näitä optikolla muotoiltavana, josko sen jälkeen istuisivat paremmin. Muuten kyllä kivan näköiset ja linssit ovat hyvät.
Hyvät sinivalolasit, migreeniäkin helpottavat
Pojalle iltalaseiksi. Perheessä käytössä päivälasit niin halusimme saada nämäkin käyttöön. Toimii. Teini tykkää :)
Ihanan lempeä värimaailma näiden iltalasien kanssa❤️
Aivan parhaat lasit. Huomaa olossa jo muutaman minuutin käytön jälkeen ja uni tulee nopeammin. Puolison kanssa taistellaan kumpi pitää joten pitää ostaa pian toiset.
Erittäin hyvät!
6/5!! Nää on loistavat lasit, suosittelen! Mailma kirkastui! Ihan mahtavat autoa ajaessa, ei tartte siristellä yhtää! Toimii myös illalla hyvin, tulee unikin nopeammin ku pitää näitä nenällä esim iltavuoron jälkeen!
Illan lopuksi nämä päässä hiukan TV-aikaa
Paras
Ihanan kevyet eivätkä silmäni ole läheskään niin väsyneet kuin ennen. Erittäin hyvä ostos:)
Rauhoittava ja miellyttävä kokemus iltaisin. Kirkkaat valot eivät häikäise enää.
istuvat mukavasti. ja ajavat asiansa hienosti. helpottaa unen saantia ja päivällä näkee kaiken kirkkaasti eikä tarvitse siristellä silmiä
Lasit istuu hyvin ja näyttää että myös vaikuttavat illalla.
Sujuvat kaupat ja ihanat lasit
Todella huippu lasit silmien jaksamiselle. Hyvät päässä. Nopea toimistus ja parasta asiakaspalvelua.
Las gafas son estupendas y de muy buena calidad.
Uskomattomat lasit! Heti ekasta illasta lähtien paremmat unet! 🤩
.
Huomaan lasien käytön aloittamisen jälkeen nukahtavani nopeammin. Sopivat hyvin lukulasieni päälle tarvittaessa, hivenen isot ovat sitten käyttää televisiota katsoessa, mutta ei haittaa merkittävästi. Hyvä ostos!
Nää lasit on mun iltojen pelastus. Rauhoitun nukkumaan paremmin kun tv tai puh ei heijasta sinistä valoa. Koko maailma näyttää paremmalta.
Lasit istuvat hyvin, aluksi vaatii totuttelua mutta huomaa että silmät ei ole niin väsyneet kun käyttää iltaisin näitä.
Toimii! Pidän niitä lähinnä ilta-aikaan tv,tä katsellessa.
Muutaman illan käytön jälkeen huomasin nukkuvani selvästi paremmin. Se oli juuri se mitä hainkin eli valinta osui kohdalleen.
Nukahtamisviive on pienentynyt ja unenlaatu parantanut lasien käyttöönoton myötä.
Käytän laseja omien silmälasien päällä tvtä katsoessani. Kun on käyttänyt niitä hetken ei edes huomaa että ne on oranssit 🙂. Toimii hyvin.
Hieman liian leveät pokat itselle.
Store owner replied: Tiina-hyvä <3 ! Ihanaa, kun olet tehnyt ostoksen verkkokaupassamme. Tuotteillamme on yhden kerran maksuton vaihtomahdollisuus. Vaihdetaan ilman muuta kapoisempaan malliin, jotta lasit istuvat paremmin. Kajo-malli on kaikista kevein ja levein mallimme. Jos malli tuntuu muuten mieluisalta, niin sankoja reilusti muokkaamalla saat Kajoistakin varmasti hyvin päässä pysyvät silmien suojat. Laita meille viestiä osoitteeseen info@northray.fi, niin autamme mielellämme, että voit olla täysin tyytyväinen ostokseesi <3 !
Ovat olleet niin vähän aikaa käytössä etten vielä osaa sanoa vaikutuksista.
Ostin lahjaksi teinipojalle, taisi tykätä.
Istuvat hyvin ja tuntuu kevyeltö. Kiitos
Ostin lahjaksi miehelle. Vaikka hänellä on aika iso pää, niin lasit ei sittenkään näytä istuvan kovin hyvin. Toimii kun on ihan paikoillaan mutta vähänkään päätä liikuttaessa ne tippuu nenälle.
Hyvin meni.
Loistava tuote.
Pitkän haaveilun jälkeen tilasin itselleni nämä lasit. Ovat hyvin kevyet käytössä, eivät paina eivätkä ahdistaa. Huomaan, että vaikuttavat positiivisesti unenlaatuun ja muutenkin antavat fiiliksen silmille, että eivät ole niin rasittuneet. Suosittelen lämpimästi.
Unen laatu parantunut selkeästi.
Laadukkaan oloiset kevyet lasit jotka istuu päähän hyvin. Mukava käyttää ja uni tulee helpommin iltaisin vaikka myöhään treenailenkin. Asiakaspalvelu aivan timanttia!

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!
Eyeglasses and blue light
I wear prescription glasses; how can I protect my eyes from the harmful effects of blue light?
If you wear prescription glasses, we recommend our clip-on lenses that are easily attached over your glasses. All our clip-on lenses fit amazingly well over various styles of eyeglasses.
Is it possible to try on the glasses?
You can try on different glass models by ordering a Home Try-On Kit! It's easy and fun to try on all our models at your leisure at home.

Yes, all frames made of TR-90 material are moldable. See the molding instructions in the video below.
