Methodology

How we compare online glasses retailers

Our comparisons are designed to help UK shoppers choose a sensible route before ordering prescription glasses, sunglasses, lens upgrades or reglazing online. We do not treat the cheapest visible frame price as the answer.

What we compare before recommending a retailer

We compare the finished buying situation: total pair cost, lens suitability, fit support, delivery, returns and aftercare. A cheap frame only wins when the whole order still works.

What we compareWhy it mattersExample risk
Frame priceOften excludes prescription lenses, delivery and upgrades.A cheap frame becomes expensive after thinning and coatings.
Lens optionsThe lens package decides whether the finished pair is useful.Wrong index, coating or tint adds cost without solving the problem.
Fit supportFrame size, PD, varifocal height and adjustments can matter more than price.An online frame looks right but fits badly or needs local adjustment.
Returns and remakesPrescription lenses may have exclusions or different support routes.The buyer assumes a simple return but the issue needs a remake or support case.

Buyer-first comparison principles

We compare the finished buying journey: the frame, prescription lens choice, thinning, coatings, delivery, returns, support and fitting risk. A retailer can be useful for one buyer and a poor fit for another, so our pages explain situations rather than declaring one universal winner.

What our comparison is designed to do

UK glasses shoppers rarely compare like with like. One retailer may show a low frame price, another may include a basic lens, and another may offer stronger fitting or store support. Our job is to slow the decision down enough that the buyer checks the full order before clicking through.

We write for everyday buyers: people replacing a pair, trying online glasses for the first time, comparing prescription sunglasses, deciding on thinning, or wondering whether to reglaze existing frames. The site is information only. It is not optical, medical or dispensing advice.

1

Total order cost

We look beyond frame price and consider the basket after lenses, coatings, thinning, delivery and discount terms.

2

Lens clarity

We check whether lens choices are explained clearly enough for a shopper to understand trade-offs.

3

Fit and prescription risk

We flag when PD, frame size, strong prescriptions, varifocals or child fitting may need extra care.

4

Delivery and production

We separate dispatch language from made-to-order lens production where that affects expectations.

5

Returns and support

We check whether the return or remake route is clear, especially for prescription lenses.

6

Reglazing suitability

For reglazing, we focus on frame condition, postage, turnaround and what happens if a frame is unsuitable.

How we read retailer information

What we checkRetailer terms, delivery pages, returns wording, lens menus, product categories, support routes and published guidance.
Why it mattersMost buying problems happen after the headline price: lens upgrades, measurements, production times, returns and support.
What can changePrices, codes, stock, delivery estimates, discount exclusions and return wording can change quickly, so shoppers should confirm live terms.
How we updateCommercial pages and comparison tables carry a checked date. We update pages when source checks or corrections show a material change.

How affiliate links affect rankings

Some retailer links may earn commission at no extra cost to the visitor. Commission does not buy placement, and a retailer can be mentioned without an active affiliate relationship. The commercial test is still buyer suitability: who might the retailer suit, who should be cautious, and what should be checked before ordering.

Where a link is commercial, we use neutral wording such as "Check current prices", "Visit retailer" or "Compare before ordering". We avoid pressure language because prescription glasses are a fit and suitability decision, not a quick impulse purchase.

What we do not do

  • We do not provide optical, medical or dispensing advice.
  • We do not guarantee live prices, voucher codes, delivery dates or stock.
  • We do not rank retailers only by cheapest advertised frame price.
  • We do not recommend online ordering where the buyer needs professional fitting or clinical support.

Corrections and source checks

If a retailer page is out of date, a retailer or reader can send a correction through the contact page. We look for factual evidence such as a current policy page, support page or product page. Corrections can change wording quickly, but they do not automatically change editorial judgement.

Use the methodology with the comparison

Read the scoring approach, then compare retailers by the buying situation that matches your order.
