Lenses & Prescriptions

We currently offer Single Vision prescriptions lenses for spectacles, including anti-scratch and anti-glare coatings. Shop our spectacles here.

Single vision lenses are designed to help you focus on things either near Reading), far Distance) or at arm’s length Computer or Intermediate).

Unfortunately we don't cater for multifocal sunglasses or spectacles (bifocals or varifocals). We're working on this, thanks for your patience.

In order to fit your spectacles with the correct lenses, we require a copy of your prescription. Please upload a photo or scanned copy of this when you are prompted to on checkout, or email it to us - info@monclondon.com.

When fitting prescription lenses, we must abide by what's written on your prescription. These values change every few years, so before ordering with us please ensure that you have been to have your eyes tested in the last two years. When buying spectacles from us, we must have your Pupillary Distance or PD which is the distance between your pupils in mm. Your previous dispensing optician will have this on your record, but not necessarily write it on your prescription. When ordering your prescription spectacles from us, it would be great if you could supply us with your PD. If not, you can measure it yourself at home.

For our standard Single Vision spectacle lenses we recommend and use the following based on your sphere values. Sphere values are marked SPH on your prescription:

  • For sphere values (SPH) up to +/-3, we use 1.5 or 1.6 lens designed for basic prescriptions. (+£0)
  • For sphere values (SPH) between +/- 3 and 5, we use 1.67 lens designed for medium prescriptions. (+£25)
  • For sphere values (SPH) between +/- 5 and 8, we use 1.74 lens designed for stronger prescriptions. (+£50)
  • For sphere values (SPH) +/- 8, please email us at info@monclondon.com for more information

If you are unsure on what type of lenses you require, please call us on 02031760259 or email us at info@monclondon.com. If you checkout and we think you need a certain lens type, we will get in touch to discuss this after you've order your spectacles.

Currently our prescription lenses are made from polycarbonate plastic. Right now, we are unable to make our prescription lenses from glass, but we are working hard to change from plastic prescription lenses to glass prescription lenses

Unfortunately, we can’t make spectacle lenses from a contact lens prescription as they are slightly different.

For frame styles: Løkka, Monti and Principe, we use Italian-made glass lenses. Our glass lenses are:

  • UV400 Category 3 optical glass, protecting against 99100% UVA and UVB sun rays.
  • Infrared Blocking
  • Chemically hardened to withstand knocks and drops.
  • Hydrophobic
  • Contain anti-reflective coatings as standard

For frame styles: Kallio, Gràcia, Kreuzberg , London Fields and Södermalm, we currently use CR39 plastic, but we are working to eliminate plastic sunglass lenses by the end of 2019. Our CR39 plastic lenses are:

  • UV400 Category 3 sun lenses protecting against 99100% UVA and UVB sun rays.
  • Come with scratch resistant hard coating
  • Made by Divel Italia

*We have chosen to go back to traditional methods and we’re doing so in order to help protect our future. Glass is easier to recycle than plastic and glass lenses happen to be harder than their plastic counterparts so they don’t scratch as easily. They also offer better optical quality and a high refractive index, meaning we can use lovely thin lenses.

Technological advancements mean the risk of smashing glass lenses is smaller than you may imagine. But if you’re still concerned, worry not because MONC is committed to replacing any lenses that fall victim to a poolside incident that results in a crack or shatter. If this should unfortunately happen, please email us at info@monclondon.com for more information.
