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.

What kind of frames can be lensed?

Linssittämiseen sopivat kehykset:

Kaikki 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

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

Frequently asked questions

Frequently asked questions

What is the PD value?

PD-arvo eli silmäteräväli
PD-arvo (tai KV-arvo) ilmoittaa pupillien etäisyyden toisistaan millimetreinä. PD-arvolla määritetään linssin optisen keskipisteen oikean paikan.

PD-arvo ilmoitetaan useimmiten molemmille silmille erikseen. Luvut voivat olla esim. 30 ja 31. Tämä tarkoittaa, että oikean silmän pupillin etäisyys nenänvarresta on 30mm ja vasemman etäisyys 31mm.

Jos reseptissäsi ilmoitetaan silmävälille vain yksi arvo (esim. 60), jaa tämä luku kahdella. PD 60 tulee täten ilmoittaa seuraavasti: PD 30 (vasen silmä = OS) ja PD 30 (oikea silmä = OD). Jos PD-arvo on ilmoitettu kahtena lukuna, esim. 66/63, on ensimmäinen arvo tarkoitettu kaukolaseille ja toinen lähilaseja varten.

Lensing the new frame

You can also send us new frames to have lenses made.

Multi-power: A frame-specific cut-off height is required for the manufacture of Progressive lenses. Please contact our customer service before shipping the frame.

Single power: We lens all suitable new plastic and metal frames.

Ordering Progressive lenses

You can also order Progressive lenses through our online shop .
In order to find out the limiting height, we hope that you have your old Progressive lenses in place when ordering Progressive lenses.
It is advisable to purchase your first pair of Progressive lenses through an optician’s shop, as the initial fitting is important and the first pair of Progressive lenses often take some getting used to.

How long does it take to get used to the new lenses?

We recommend getting used to your new lenses every day for at least two weeks. Usually, the human visual system adapts to new powers and lens types within two weeks. If the changes to your previous lens power are large, it may take even longer to get used to them. If necessary, please contact our customer service.

Eyeglass lenses are individual medical devices that we manufacture according to optical standards and the strengths you specify. As a guarantee of our quality, we provide a 30pv satisfaction guarantee on our lenses from the day you receive them.

Can I get eyeglass lenses at Linssikauppa prices from opticians?

You are unlikely to find similar prices at an optician or optician chain.

We are the only eyeglass lens grinder in Finland, which is why we are able to offer our customers very competitive prices without compromising on quality.

Linssikauppa prices are only valid online.

What if my vision has changed since I bought the previous glasses?

If it’s been more than 6 months since your last visit to an optician or ophthalmologist, or if you suspect your vision has changed, we recommend you visit either an optician or ophthalmologist for a vision check.

Where are Linssikauppa lenses made?

Our lenses are manufactured in our Liedo lens factory in Southwest Finland and delivered directly to our customers from there. Linssikauppa’s lenses carry the Key Flag mark, which indicates a high degree of domesticity.

Do products have a right of return?

The lenses are non-refundable. The lenses are made to the customer’s vision, so they are a custom-made product and are not subject to the normal 14-day return period under consumer protection law. However, we are confident in our quality and offer a 30 day satisfaction guarantee on our lenses , meaning that if you are not happy with your lenses we will make you new ones free of charge. Read our ordering and delivery conditions.

How long is the delivery time for lenses?

Linssitilauksen vaiheet ja kestot

  • Palautuskuori lähtee sinulle yleensä tilauspäivänä: kirjeen saapuminen kotiosoitteeseesi kestää n. 3-7 arkipäivää.
  • Linssien valmistusaika: n. 10 arkipäivää.
  • Valmiiden lasien saapuminen sinulle: n. 3-7 arkipäivää.

What is your satisfaction guarantee?

We offer a 30-day satisfaction guarantee: if you’re not happy with your lenses, we’ll replace them with a similar lens of a different type, free of charge. If the replacement lenses are more expensive, you only pay the difference. Read more about the satisfaction guarantee.

Eyeglass lenses are medical devices manufactured for individual use and therefore the 14-day right of withdrawal for distance sales does not apply. You can read our terms of delivery here.

Do the lenses have a warranty?

We provide a two (2) year warranty on our lenses and coatings against defects in materials and workmanship. This warranty does not cover damage caused by negligent or improper handling or heat (e.g., from a fireplace). Please follow the care instructions provided with your order.

What happens to my old lenses?

We’ll ship the lenses that have been removed from your old frames back to you with your new lenses.

How do I care for my eyeglass lenses?

Clean your lenses regularly with a lens cleaning agent. Avoid wiping the lenses with a dry cloth. Eyeglasses should be stored in a clean case of suitable size. Avoid exposing lenses to heat or rapid temperature changes. Detailed care instructions will be provided with your order. You can order products suitable for cleaning from our online shop.

Read more detailed instructions for cleaning your glasses.

See our online shop for eyewear cleaning products.

Can I order lenses without strengths?

Yes you can. Select the power levels, the features you want (e.g. blue light protection and anti-fog) and order the lenses.

You can also order Sunless lenses without strengths.

Are lenses with prismatic power (prisms) available from your online shop?

No, you can’t. We do not sell prism lenses online, as prism lenses often take some getting used to and should be fitted with the help of an optician.

Are eyeglass lenses medical devices?

The lenses in the Linssikauppa are medical devices (MD=Medical Device) manufactured for individual use and meet general safety and performance requirements.
Linssikauppa (Piiloset) is responsible for the MDR (=Medical Device Regulation) compliance of the lenses fitted to the customer’s own frame. Linssikauppa is not responsible for the characteristics or quality of the customer’s frames. Our experts will check the suitability of each frame for fitting new lenses and, if necessary, we will contact the customer if we have any doubts about the lens compatibility of the frames.

Prescription and prescription for spectacles

How do I report my strength/glass prescription information?

When you place your order, you can choose from three ways to provide us with your spectacle strength data:

  • Send us a picture of your lens prescription and our customer service team will fill in your lens details.
  • Please enter your lens prescription details when ordering.
  • Please indicate your lens prescription only after you have placed your order.
    After placing your order, you will be sent a link to the form where you can enter your prescription details.

Please contact our customer service team if you need help filling your lens prescription.

Where can I get my lens prescription?

You can get a prescription for glasses from an optician or ophthalmologist. Opticians often give you a prescription for lenses on a separate card. The prescription can also be on the optician’s customer system.

Nowadays, prescription information for glasses can also be found in MyCanada if the optician or ophthalmologist has joined MyCanada. Log in to MyClient ->

We recommend that your lens prescription is no more than 6 months old, so that the lenses can be manufactured to the correct strengths.

How do I interpret my lens prescription?

Your spectacle prescription will contain all the values and information you need when ordering your spectacles. Prescriptions may differ depending on which optician you have visited. Your prescription should show the following basic values:

Intensity (power / sphere / spherical intensity)
Minus values refer to littittleness and plus values to sphericity.

Cyl/Cylinder value
The first value related to the correction of dispersion, the cylinder value, measures the amount of astigmatism, or dispersion. Note! The number showing the Cylinder Value is most often reported as negative, but if the Cylinder Value in your recipe is marked as positive, select a positive value.

Ax/Axis/Cylinder axis
The second value needed to correct for astigmatism is expressed as a number of degrees and indicates the position of the astigmatism in the eye. The Axis value indicates in which direction the refractive error is corrected. If you do not have astigmatism (diffraction error) the cylinder and axis values are blank.

Extra power/ADD
Value related to presbyopia, used in Progressive lenses. The added value is the difference between distance power and reading power in diopter units.

Interpupillary distance/PD/KV
The PD value indicates the distance between the pupils in millimetres. The PD value determines the correct position of the optical centre of the lens.

If your prescription specifies only one value for the eye width (e.g. 60), divide this number by two. PD 60 should therefore be indicated as PD 30 (left eye = OS) and PD 30 (right eye = OD). If the PD value is given as two numbers, e.g. 66/63, the first value is for distance glasses and the second for near glasses.

Any other indications that may be found on your prescription:

Free vision Indicates the accuracy of your vision without correction, i.e. how well you can see without glasses.

Corrected vision Indicates your visual acuity with correction, i.e. how well you can see with glasses.

What is the PD value?

PD-arvo eli silmäteräväli
PD-arvo (tai KV-arvo) ilmoittaa pupillien etäisyyden toisistaan millimetreinä. PD-arvolla määritetään linssin optisen keskipisteen oikean paikan.

PD-arvo ilmoitetaan useimmiten molemmille silmille erikseen. Luvut voivat olla esim. 30 ja 31. Tämä tarkoittaa, että oikean silmän pupillin etäisyys nenänvarresta on 30mm ja vasemman etäisyys 31mm.

Jos reseptissäsi ilmoitetaan silmävälille vain yksi arvo (esim. 60), jaa tämä luku kahdella. PD 60 tulee täten ilmoittaa seuraavasti: PD 30 (vasen silmä = OS) ja PD 30 (oikea silmä = OD). Jos PD-arvo on ilmoitettu kahtena lukuna, esim. 66/63, on ensimmäinen arvo tarkoitettu kaukolaseille ja toinen lähilaseja varten.

Lens characteristics and lens selection

Do I need single or multi-power (progressives)?

You can choose the right lens for your needs from our online shop. You can order single power lenses for distance or close-up. With multi-powers, you can see both near and far with the same lens.

What is lens thinning and refractive index?

Lens thinning refers to the ability of the lens material used to refract light more efficiently, allowing the lens to be made thinner and lighter – especially at high powers. Related to this is the refractive index ( refractive index), which indicates the ability of the lens material to refract light: the higher the refractive index, the thinner the lens.

The thinned lenses are made of a denser plastic material that refracts more light. Not only do they look lighter and sleeker in the frame, they also offer practical benefits: they are lighter, more comfortable to wear and contain 100% UV protection to shield the eyes from harmful ultraviolet rays.

Our online shop offers a range of lens options for different price ranges. The lens types differ in terms of both power (refractive index) and UV protection:

  • Unthinned: refractive index 1.5 – No UV protection (basic lens)
  • Multifocal: refractive index 1.6 – 100% UV protection, thinner and lighter (+39 € / pair of lenses)
  • Double thinned: refractive index 1.67 – 100% UV protection, ultra thin and lightweight lens (+79 € / pair of lenses)

By choosing thinned lenses, you can improve the comfort and appearance of your glasses, especially when you need strong lenses or want to ensure full UV protection.

How do I choose the right index?

Thinned lenses are made of a “tighter” plastic material and refract light more. Thinner lenses are lighter and thinner, and the thinned lens has 100% UV protection. Our double-thinned lenses have a refractive index of 1.6 and double-thinned lenses 1.67.
A double-thinned lens is not optically better than a single-thinned lens. At low intensities, we therefore recommend only a single-thinned or an unthinned lens.

Single discount brings an additional price of 39€ for a pair of lenses
Double discount brings an additional price of 79€ for a pair of lenses

We recommend to choose the single reduction (1.6) with intensities -2.0- -4.50 and + 2.0- + 4.0. Double reduction (1.67) with intensities -4.0- – 7.0 or +3.50- +5.50. If you have larger spectacle powers, please contact our customer service.

Do the lenses have UV protection?

Ultraviolet radiation has been shown to damage eye cells, so eyes should be protected from UV radiation. See the lens options to see which lenses have UV protection.

Refractive indices and UV protection for single and multiple powers:

  • Non-diluted (refractive index 1.5): no UV protection
  • Refracted (refractive index 1.6): 100% UV protection,
  • Double thinned (refractive index 1.67): 100% UV protection
What are the fields of vision for progressive lenses

In multi-effects, you can choose between Good and Wide. The Good monitors offer a good range of vision for near and far. Wide mono powers involve more steps in the manufacturing process and provide the best possible near and far field of view.

What is an anti-fog coating?

Our anti-fog nanocoating is the first physical coating available in the Nordic countries that permanently and effectively prevents fogging of eyewear. Well suited to northern conditions, the lenses prevent fogging and make everyday life easier, whether at work, in sports or outdoors. Read more about the anti-fog coating.

What is polarisation?

In addition to normal glare, polarised sunglasses effectively eliminate reflections from horizontal surfaces, such as light bouncing off water, snow or wet roads. This makes polarised sunglasses particularly suitable for drivers, water sports enthusiasts and spring sunbathers, for example.

Polarised lenses have a special filter in the coating or lens material that filters out horizontal light rays.
