Every October the same content appears: practices promoting coloured contact lenses as a costume accessory, priced and marketed like sunglasses. It is seasonal, it performs well, and it sits on top of a regulatory misunderstanding.
Plano cosmetic lenses correct nothing, which is exactly why people assume they are unregulated. They are medical devices in most jurisdictions regardless of power, and supply generally carries the same fitting and aftercare obligations as any other lens.
The regulatory trigger is that the object sits on the cornea, not that it changes refraction. A lens with no prescription still restricts oxygen, still needs to match corneal curvature, and still causes serious harm when it does not fit or is not cleaned properly.
This is why enforcement action in this area recurs and why the sellers targeted are usually not opticians at all. The market stall and the costume shop are the problem; a practice whose marketing sits alongside theirs has chosen unhelpful company.
Emergency eye services see a predictable October spike: corneal abrasions, infections, and occasionally permanent damage, almost all from unfitted lenses bought without any professional involvement.
That gives the practice something far better than an offer. This is a genuine, local, seasonal public safety message with a specific audience, and it is the same shape as the content that works so well for other clinical professions.
The aim is to own the conversation without joining the part of it that causes harm. It also happens to reach far more people than a discount post, because worried parents share it.
None of this means the category is off limits. It means the sale carries the same obligations as any lens fitting: specification, fit, instruction and aftercare, with the same records.
Practically, that changes the marketing timeline. A properly fitted cosmetic lens needs an appointment well before the last week of October, so the content has to run in early autumn. A practice that plans it that way converts a compliance constraint into a scheduled campaign, which is roughly the opposite of where most end up.
Zero-power lenses are medical devices, so run October as a safety message and a fitting appointment booked weeks ahead, never as an accessory promotion.
