Electronic shelf labels in opticians

Electronic shelf labels fit an optician’s practice only partly. The frame display holds dozens of pieces, but the final price of a pair of glasses depends on lenses and prescription, and most sales run through an appointment. The hours saved on price changes, which carry the case in a supermarket, are small here.

What remains is tighter control of promotions and brand information on the display.

What an optician actually sells

The market data we could verify comes from the continent, not the UK. In Spain, the DBK Sector Observatory puts opticians’ turnover at 3,035 million euros in 2025, across about 9,800 points of sale. By product, ophthalmic lenses are around 45% of sales, frames about 20%, contact lenses 16% and sunglasses 14%. In Germany, the ZVA reports a trade turnover of 7.025 billion euros in 2025 including VAT, of which spectacle optics is 5.733 billion and contact lenses 0.616 billion, sold through 10,700 specialist shops.

Different countries, different definitions, so treat them as a pattern rather than a UK benchmark: the frame the customer sees is a minority of what they pay for. Lens, coating and index are decided at the dispensing desk, and priced there.

The display: frames and format

The practical problem is space. A frame hangs on a panel or a rotating stand at eye level, and customers try it on. A large label hides the piece or pushes it aside. Reasonable options:

• A small label beside each frame. Ask each vendor for its smallest formats, and test a real one under your own lighting before buying, since display spotlights cause glare on the screen.
• One label per block. A screen per module or brand showing the price of the range rather than the piece. It works when pricing is uniform, as with many own-brand or single-price collections.
• Paper. A card with the module price is still legitimate if prices change a few times a year.

This is not a sector for one label per reference. A frame turns over slowly compared with a grocery line, so the cost per label pays back more slowly. The TCO calculator lets you check it with your own numbers, and the guide on what an electronic shelf label is covers sizes and technologies.

Frames sit between fashion, with seasonal collections, licensed brands and campaign price changes, and jewellery, with small pieces of notable unit value where appearance matters. What they do not share with either is that in an optician most of the price is set afterwards.

The price that is not the frame’s

The Price Marking Order 2004 requires a trader who indicates that a product is for sale to consumers to show its selling price, defined as the final price including VAT and all other taxes. In an optician the question is which price. There are three possible answers, each with consequences on the screen:

1. Frame only. The easiest to label, but the customer may read it as the price of the glasses.
2. Frame plus a reference lens. A “from” price with visible conditions. This is a commercial decision that must be kept current when the reference lenses change, and a label that updates in bulk does save work here.
3. Package price. “Complete glasses from X”, with the frame and basic single-vision lenses. It changes with campaigns.

The label does not settle the ambiguity; whoever designs the pricing policy does. What it does is stop the display saying one thing and the till another.

Offers on lenses: where labels are used most

Promotions are the strongest argument in the sector. An optician promotes heavily: second pair, coatings included, seasonal discounts, contact lens subscriptions. That means changing the messages of a whole module at once, and doing it properly.

Two things apply:

• Misleading offers. Section 226 of the Digital Markets, Competition and Consumers Act 2024 defines misleading actions, including true information presented in a misleading way. A “was” price, a “free” item or a bundle are caught because of the saving they suggest. The CTSI’s Business Companion guidance on pricing practices is the practical reference; see also our guide to reference prices and was/now pricing.
• Timing. If an offer runs from the 1st to the 15th and the price does not return at midnight on the 16th, that is a problem, and a visible one. Labels that log who changed what and when make it easier to show the offer ended on time, provided that log exists. Ask the vendor for it.

Health claims: the limit the trade knows

Many of an optician’s products are medical devices: prescription glasses, contact lenses and their solutions. A price or a brand name raises no issue. A line such as “protects your eyes from blue light” is a claim about a product, and each screen showing it should have passed the same check as a poster or an advert. The advantage of a screen is that it can be pulled in minutes; the risk is that changing a message is so easy that it skips that check. Decide who may publish copy and who reviews it. We have not verified the UK rules on advertising medical devices, and that point is flagged for legal review.

If the question is return on investment

The business case for an optician looks nothing like a supermarket’s:

With that profile, the main argument is rarely saved hours. It is keeping the display, the website and the till consistent, and launching a campaign on the same day across every store in a chain. For an independent with a single shop the sums may come out against, and that is a fine answer. For a chain with dozens of stores the balance shifts, and integration with the practice management system matters more than the screen.

What to check before deciding

• The smallest label available, tested on the display under its own lighting.
• Whether the system can show more than a price, and who maintains that data.
• How it records who changed each message and when.
• How a campaign with an end date is handled: scheduled, or changed by hand.
• Whether the vendor covers integration with the practice management software.
