Why Does ChatGPT Recommend a Different Optician Instead of You?

🇫🇷 Version française

Your customers still come back to renew their glasses every couple of years like clockwork, but new prescriptions — from people who've never set foot in your store — keep getting rarer. It's probably not your store that changed. It's how people choose an optician that did.

A new prescription in hand, or a frame that snapped the night before an important meeting: these used to be moments where people typed "optician near me" into Google and picked from the first few results. A growing share of your prospects now does something else: they open ChatGPT or the assistant built into their phone and ask directly, "which optician should I choose in [their city]" or "where can I find contact lenses of this brand near me". The AI suggests one or two names. If yours isn't one of them, that person walks into a competitor's store — and you'll never know the request even existed.

Your loyal customers keep coming back, but new prescriptions keep getting rarer: why?

It's a quiet symptom: the renewal of your existing customer base masks, for a while, the slowdown in new faces walking through your door. You haven't changed your frame selection or your service. What changed is the first instinct of someone looking for an optician for the first time in a given area: they no longer compare three sites themselves, they let an AI suggest a name for them.

Why an AI doesn't know you yet

When ChatGPT or Perplexity answers "which optician should I choose in [city]", it relies on whatever it finds clearest on the web at that moment: your site, your Google Business listing, reviews, mentions elsewhere. If your site doesn't explicitly state which frame and lens brands you carry, whether you handle insurance and prescriptions, your hours, or any specialties (low vision, rigid lenses, kids), the AI has nothing concrete to cite. It falls back on a competitor whose site answers these questions without hesitation, even if their offering isn't actually better than yours. This is exactly what GEO (Generative Engine Optimization) addresses: making your business readable and citable by these AIs, not just visible on Google.

What this actually means for your store

It's not one lost prescription that matters, it's the compounding effect: every person directed to a competitor by an AI potentially becomes a loyal customer for that competitor, coming back at every renewal for years. Your business keeps running on its existing base, but that base renews itself less and less. It's a slow signal, often invisible until you measure it directly.

What you can check yourself in 5 minutes

1. Open ChatGPT and ask the question a new customer would ask: "which optician should I choose in [your city]" or "where can I find an optician that carries [contact lens brand] near me".
2. Check whether your store shows up, at what rank, and which competitors are cited instead.
3. Run the same test on Perplexity and Gemini: results often differ from one engine to another, which already shows where you're most exposed.
4. Reread your own site: does it clearly answer "which brands do you carry?", "do you handle insurance?" and "what are your hours and exact address?". If it's not immediate for you, it isn't for an AI either.
