FAQs

We currently offer Single Vision and Multifocal prescription lenses for spectacles and sunglasses, which include anti-scratch and anti-glare coatings as standard. Shop our spectacles here.

Single vision lenses are designed to help you focus on things either near (reading), or in the distance.

Bifocal lenses combine two prescriptions into a single pair of glasses. The top part of the lens allows you to see in the distance, while the lower part helps you see up close.

Varifocals are multifocal lenses with a graduated change from top to bottom, allowing you to see up-close as well as in the distance, without having to switch frames. Unlike Bifocals, there is no definitive line between the top and bottom half of the lens.

    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.

    In order to fit your spectacles with the correct lenses, we require a copy of your prescription. After you have checked out, you will be prompted to email your prescription to us. If for some reason you do not receive this email, please send your prescription to us at 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 (PD), which is the distance between your pupils in mm. Your previous dispensing optician will have this on your record, but may not necessarily write it on your prescription. When ordering your prescription spectacles from us, we kindly ask if you could provide us with this measurement. If you do not have this, you can measure it yourself at home.

    For prescriptions with higher SPH values and Multifocal lenses, we require your Ocular Centre Height measurement. Your OC height is measured as the vertical distance of the centre of your pupils to the bottom of your lens, specific to your chosen frames. More information can be found on our varifocal help page.

    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.

    Our prescription lenses are currently 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.

    For Bifocal 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. (+£50)
    • For sphere values (SPH) between +/- 3 and 5, we use 1.67 lens designed for medium prescriptions. (+£75)
    • We do not currently offer Bifocal lenses for prescriptions with SPH values above +/-5. Apologies for the inconvenience.

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

    We use Italian-made glass lenses. Our glass lenses are:

    • UV400 Category 3 optical glass, protecting against 100% UVA and UVB sun rays
    • Infrared Blocking
    • Chemically hardened to withstand knocks and drops.
    • Hydrophobic
    • Contain anti-reflective coatings as standard

    For our original frame styles of Gràcia, Kreuzberg, London Fields and Södermalm, we use CR39 plastic. Since 2019, our sunglasses have been made with glass lenses. 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. If you’re still concerned, worry not. 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.
