How to Reglaze Second-Hand Glasses & Replace Lenses
Your complete guide to taking pre-owned frames to high-street opticians or UK online reglazing specialists
The Short Answer
Frames are forever, but lenses are swappable. When you buy pre-owned glasses on Squinted, you are buying high-quality frames as a structural starting point. You can take any pre-loved spectacle frame to a high-street optician or online reglazing service to have new prescription lenses fitted specifically for your eyesight.
How to Reglaze Pre-Loved Frames in 3 Steps
Find the "Bones"
Search Squinted for designer shapes or vintage styles you love. Don't worry about any lenses currently fitted — you are buying the quality frame structure.
Choose Your Optician
Take your frames to your favourite local high-street optician or order a mail-in pack from an online UK reglazing service. Most optical shops routinely reglaze customer frames.
Pop, Scan & Swap
The optician will pop out the old lenses, scan the rim shape, and cut fresh lenses to match your precise prescription — including anti-glare, blue-light, or tinted options.
Why Reglaze Pre-Owned Eyewear?
💰 Major Cost Savings
Even after adding the cost of new prescription lenses, buying pre-owned frames saves you hundreds compared to new retail prices.
👓 Tailored Fit
Combine luxury design or rare vintage styling with lenses cut precisely for your current visual prescription.
🌱 Sustainable Choice
Give durable, high-quality acetate and titanium frames a second life rather than letting them end up in landfill.
Important Prescription & Safety Guidelines
1. Squinted Is a Marketplace, Not an Optician
Squinted Ltd operates a peer-to-peer marketplace connecting buyers and sellers of pre-owned frames. We are not an optician, optometrist, or optical retailer. We do not test sight, write or check optical prescriptions, or supply prescription lenses.
2. Existing Lenses Belonged to the Previous Owner
Many frames listed on Squinted will arrive with lenses fitted by their previous owner. You should assume these lenses were ground for someone else’s eyes, focal points, and pupillary distance. Wearing someone else's prescription can cause headaches, eye strain, blurred vision, and can be dangerous when driving or cycling.
3. Re-Lensing Is the Buyer's Responsibility
It is the buyer’s responsibility to take any purchased frame to a registered optician or professional reglazing provider before relying on it for vision correction.
4. Non-Prescription & "Plano" Items
Sellers are asked to state clearly in their listing whether an item has prescription lenses, non-prescription (plano) lenses, or sunglasses lenses fitted. If a listing is unclear, ask the seller directly before buying.
Frequently Asked Questions
Can opticians put new prescription lenses into second-hand frames?
Yes. High-street opticians (such as Specsavers, Boots, or Vision Express) and UK online reglazing specialists routinely fit new custom single-vision, bifocal, or varifocal lenses into pre-owned frames.
Are pre-owned glasses frames hygienic to buy and wear?
Yes. Spectacle frames are durable, non-porous accessories made from materials like acetate, metal, or titanium. While Squinted marketplace guidelines ask sellers to clean frames before shipping, taking pre-owned frames to an optician or online reglazing service routinely includes a professional ultrasonic deep clean and frame alignment as standard.
How much does it cost to reglaze glasses in the UK?
Basic single-vision prescription reglazing in the UK generally starts between £15 and £40 through online specialists, or £30 to £60 at high-street opticians depending on lens coatings and index thickness.
