Prescription & Suitability Disclaimer

Last Updated: July 2026

In short: Squinted is a marketplace, not an optician. If the frames you buy have lenses already fitted, those lenses were almost certainly made for the previous owner's eyes — not yours. Before you wear any purchased eyewear to correct your vision, you are responsible for getting it checked and re-lensed by a qualified optician.

1. We Are Not Opticians

Squinted Ltd operates a peer-to-peer marketplace for buying and selling pre-loved spectacles, sunglasses, and eyewear accessories. We are not a dispensing optician, optometrist, ophthalmologist, or optical retailer. We do not test sight, write or verify prescriptions, dispense lenses, or provide any form of eyecare, optical, or medical advice.

Every item on Squinted is sold directly between a buyer and a seller. Our role is limited to providing the platform, payment processing, and buyer/seller protections described in our other policies. We do not inspect, test, or verify the optical prescription, lens power, or visual suitability of any item listed on our platform.

2. Any Lenses Already Fitted Were Made for the Previous Owner

Many pre-loved frames sold on Squinted will still have lenses fitted from when they belonged to their previous owner. Unless a listing clearly states otherwise, you should assume that any lenses already in a frame were ground to match that person's individual prescription — including their specific lens power, astigmatism correction, pupillary distance, and any varifocal, bifocal, or reading-addition measurements unique to them.

The likelihood that a stranger's prescription happens to match your own eyesight is extremely low. Wearing lenses ground to the wrong prescription will not correct your vision properly, and can cause headaches, eye strain, nausea, dizziness, or blurred vision. It can also be genuinely dangerous in situations that rely on clear, accurate vision — most importantly driving, operating machinery, or cycling.

3. Re-Lensing Is Always the Buyer's Responsibility

It is entirely your responsibility, as the buyer, to have any eyewear purchased through Squinted assessed and, where needed, re-lensed by a qualified, registered optician before you rely on it for vision correction. This applies whether you are buying frames with lenses already fitted, or empty frames that you intend to have lenses fitted into for the first time.

We'd recommend treating any purchased frame as a stylish, structurally-sound starting point rather than a ready-to-wear prescription item — think of it the way you would a beautiful second-hand picture frame that still needs the right glass cut for it. Do not wear a purchased item to drive, operate machinery, or for any other vision-critical activity until a qualified optician has confirmed it is fitted with lenses correct for your own eyes.

4. Non-Prescription & "Plano" Items

Some items on Squinted — for example, most sunglasses, fashion frames sold as display/demo pieces, or frames explicitly listed as "plano" (non-prescription) — will not have any visual correction in them at all. Sellers are asked to state clearly in their listing whether an item has prescription lenses fitted, non-prescription lenses fitted, or no lenses at all. If a listing doesn't make this clear, please ask the seller directly before you buy, and check for yourself once the item arrives — do not assume either way.

5. What Squinted Does Not Cover

Our Buyer Protection Policy covers things like items not arriving, items that are significantly not as described, or items that turn out to be counterfeit. It does not — and cannot — cover:

  • Lenses that don't match your own prescription (unless the seller misrepresented what prescription or lens type the item had — see our Buyer Protection Policy for "significantly not as described" claims).
  • The cost of having an item re-lensed, adjusted, or professionally fitted by an optician.
  • Any discomfort, eye strain, or other effects of wearing incorrect lenses.
  • The suitability of any item for a particular eye condition, activity, or medical need.

6. Sellers: What You Need to Disclose

If you're listing a frame with lenses already fitted, please state in your listing whether the lenses are prescription, non-prescription, or unknown. This protects buyers, and it protects you — clear disclosure of lens type is treated the same as any other condition disclosure under our Marketplace Seller Terms, and helps avoid "significantly not as described" disputes further down the line.

This page should be read alongside our Terms of Service and Buyer Protection Policy. If you have questions regarding any aspect of Squinted, reach out to the Squinted Team at hello@squinted.co.uk. If you have concerns about your eyesight or need a sight test, please contact a registered optician — you can find one via the College of Optometrists or the General Optical Council.
