Choosing a thinning

We offer lenses without refraction (1.5 refractive index), with single refraction (1.6 refractive index and 100% UV protection) and double refraction (1.67 refractive index and 100% UV protection).

Recommendations

For lenses with low powers (-2.0 - 4.5 and +2.0 - +4.0) we recommend a thinned (refractive index 1.6) or unthinned lens.
Double gain is recommended for intensities (-4.0 - 7.0 or +3.5 - +5.5)

In addition to being lighter and thinner, double and triple thinned lenses offer 100% UV protection. However, a double-thinned lens is not optically superior to a single-thinned lens. We therefore recommend that you choose a thinner lens according to your strengths.

If you have a larger lens power than mentioned above, please contact our customer service.

Polarising lenses: tinted anti-glare lenses.

What kind of frames can be lensed?

Linssittämiseen sopivat kehykset:

Kaikki tavanomaiset hyväkuntoiset käytetyt ja uudet muovi- ja metallikehykset, joissa on linssit paikallaan.

Alla esimerkkejä kehyksistä, joihin olemme tehneet uudet linssit (voit klikata kuvaa suuremmaksi).

Kehykset joita ei voida linssittää:

Valmiit luku- ja aurinkolasit sekä edulliset asusteeksi tarkoitetut kehykset eivät sovellu linssitettäviksi. Valmislaseilla tarkoitetaan esim. kaupoissa myytäviä luku- ja aurinkolaseja. Valmislasien kehykset ovat usein niin heikkolaatuisia, etteivät ne kestä uusien linssien asennusta.
Siimakehykset/nylor-kehykset, joissa kehyksen alaosa on korvattu nailonlangalla.
Kehyksettömät kehykset (ns. hengettömät), joissa linssien ympärillä ei ole lainkaan kehyksiä.
Erittäin kaarevat kehykset (yleensä urheilulasit) eivät sovellu linssitettäviksi.
Puukehykset ja älylasit

Jos olet epävarma onko kehyksesi sopiva linssittämiseen voit lähettää kuvan asiakaspalvelumme arvioitavaksi.

Below you will find sample images of the frames and frameless glasses.

Processing is necessary for the purposes of the legitimate interests pursued by the controller or by a third party (GDPR Art. 6(1)(f)).

The above-mentioned legitimate interest is based on a relevant and appropriate relationship between the data subject and the controller, which results from the data subject being a customer of the controller, and when the processing occurs for purposes that the data subject can reasonably expect at the time of data collection.
