Prescription & Medical Disclaimer
Last updated:
How we make prescription (medical) glasses and contact lenses safely.
Your prescription
Please use a prescription issued within the last 2 years by a qualified optometrist or ophthalmologist. For children under 16, we recommend one issued within the last 12 months.
You can enter it on the product page, send a photo on WhatsApp, or visit our store for a free eye test.
What the numbers mean
SPH (sphere) is your main power: minus for short-sight, plus for long-sight. CYL (cylinder) and AXIS correct astigmatism; if CYL is given, AXIS is required. ADD is the extra reading power for progressive or bifocal lenses. PD (pupillary distance) is the distance between your pupils, used to centre the lenses.
Optician review
Every prescription order is reviewed by our opticians before the lenses are made. If something looks unusual, or the prescription is outside what the chosen lens can be made in, we will contact you before going ahead.
Contact lenses
Contact lenses are medical devices. Wear them only after a fitting by an eye-care professional, follow the replacement schedule on the box and never sleep in lenses unless your practitioner advises it. Remove them and see a doctor if your eyes become red, painful or your vision blurs.
Coloured lenses must be treated the same as clear lenses. Never share them.
Medical disclaimer
Information on this website is general and is not medical advice. Glasses and lenses do not replace regular eye examinations, which can detect conditions such as glaucoma early. Children, diabetics and adults over 40 should have their eyes examined regularly.
