Every June, the same thing happens in independent practices up and down the country. The sun finally shows up, and patients start asking about sunglasses. Are the ones from the supermarket any good? Do my child’s need to be that expensive? Will these dark ones protect my eyes when I’m driving? It’s the one time of year your patients raise eye protection without being prompted — and most practices answer the question at the counter, sell a pair if there’s one going, and move on.
That’s a missed opportunity, and not just a commercial one. UV damage to the eye is real, it’s cumulative, and a lot of your patients have no idea their sunglasses might be doing nothing at all. Summer is simply when they’re listening. Here’s how to turn that seasonal curiosity into proper clinical advice, a confident dispense, and a service that protects your patients all year — not just when the forecast is good.
What UV light actually does to the eye
It helps to be specific with patients, because “UV is bad for your eyes” washes straight over most people. The damage falls into two buckets: the sunburn you feel within a day, and the slow harm you don’t notice for decades.
The short-term damage
Photokeratitis is essentially sunburn of the cornea and conjunctiva. A few hours of intense UV — a bright day on the water, snow glare, a welding arc — and the surface cells get scorched. It shows up six to twelve hours later as gritty, streaming, painfully light-sensitive eyes. It’s miserable but usually self-limiting, healing in a day or two. The point worth making to patients is that if UV can burn the front of the eye that fast, it’s not a trivial thing to leave unprotected over a lifetime.
The long-term damage
This is where the real case for protection sits. The World Health Organization estimates that up to 20% of cataracts may be caused or made worse by UV exposure — a huge number when you consider how common cataract already is. Chronic UV is also strongly linked to pterygium (the fleshy growth that creeps across the conjunctiva and, in advanced cases, distorts vision and needs surgery), and there’s a body of evidence connecting cumulative exposure to macular change. Add the periocular skin — the eyelids are a common and easily missed site for skin cancers — and you’ve got a clinical conversation that goes well beyond comfort in bright light.
None of this is fringe. An AOP survey found that almost a quarter of optometrists see up to nine patients a month with an eye condition linked to UV exposure, and 15% see more than twenty. Your colleagues are already managing the consequences. The question is whether your practice is doing anything to get ahead of them.
UV is a year-round risk, not a summer one
The single most useful thing you can teach patients is that UV isn’t seasonal in the way they think. It penetrates cloud, so a grey British day still delivers a meaningful dose. It reflects off water, sand, pavement and especially snow, which is why skiers burn their eyes in winter. And it’s strongest in the middle of the day, exactly when most people are out and about without a second thought.
The AOP’s long-running “SPF for your eyes” campaign frames it perfectly: people protect their skin from the sun as a matter of routine, but treat their eyes as an afterthought. The same survey found that while 46% of people owned a pair of sunglasses, of those, nearly a quarter only sometimes checked whether they actually offered UV protection when buying them. People are wearing tinted lenses they assume are safe, with no idea what’s printed on the arm.
The group that should worry you most is children. Up to 80% of a person’s lifetime UV exposure is reached before the age of 18, and children are more vulnerable than adults — larger pupils and clearer, more transparent ocular media mean more UV reaches the back of the eye. Yet kids are the least likely to be wearing decent sunglasses. If you only push one message this summer, make it that protecting children’s eyes early is one of the highest-value things a parent can do, and it costs very little.
What “good UV protection” actually means
Patients can’t judge sunglasses by how dark they are — and that’s the dangerous part. A heavily tinted lens with no UV filter is arguably worse than no sunglasses at all, because the dark lens makes the pupil dilate and lets more unfiltered UV flood in. Your job is to translate the markings so patients can buy with confidence, whether from you or anyone else.
The marks that matter
In the UK, sunglasses should meet BS EN ISO 12312-1, the standard covering both non-prescription and prescription sun lenses. Since the post-Brexit transition, sunglasses sold here should carry the UKCA mark (the CE mark still appears on products sold across both the UK and EU). The most useful shorthand to give patients is UV400: it means the lens blocks 99–100% of UV up to 400nm, covering both UVA and UVB. “100% UV protection” means the same thing. Tell them to look for one of those, plus a CE or UKCA mark — and to be sceptical of anything that doesn’t say.
It’s also worth explaining lens categories, numbered 0 to 4 by how much visible light they absorb. Category 3 is the everyday outdoor choice for British summers, cutting roughly 80% of visible light. Category 4 lenses are very dark — fine for the mountains or open water, but not legal for driving, which trips up patients who buy the darkest pair they can find for the car. A quick word on that at dispensing saves a lot of grief.
Polarised, photochromic and clear-lens UV
This is where you add value a supermarket can’t. Polarised lenses kill horizontal glare — brilliant for driving, water and bright pavements — though they can make some LCD dashboards and phone screens harder to read, so it’s worth flagging. Photochromic lenses darken automatically in UV, handy for patients who hate switching pairs, but they’re less effective behind a car windscreen, which already blocks much of the UV that triggers them. And crucially: UV protection isn’t only for sunglasses. Most modern clear lens materials and coatings can carry full UV protection, so the patient who never wears tints can still have their eyes protected on every pair. Many patients have never been told that.
Turning summer questions into a proper service
Here’s the shift in mindset. Most independents treat sunglasses as an opportunistic add-on. The practices that do well with it treat UV protection as a clinical recommendation that happens to have a product attached — which is exactly how you’d treat dry eye drops or a myopia management lens.
Every sight test in spring and summer is a UV conversation waiting to happen. The patient with early lens changes, the keen gardener, the cyclist, the delivery driver, the parent with two kids in the waiting room — each one has a reason to protect their eyes that’s specific to them, and specific beats generic every time. From there, the natural recommendations write themselves: prescription sunglasses as a genuine second pair rather than a grudge purchase, polarised lenses for anyone who drives or spends time near water, properly fitted children’s sunglasses, and clip-ons or photochromics for patients who won’t carry two pairs. None of this is pressure selling. It’s joining up a real clinical need with the products that meet it — and it lifts your second-pair rate at the same time.
A simple summer eye health workflow
You don’t need a new clinic or extra kit. You need three habits, run consistently across the team.
Flag it before they arrive. A light-touch pre-season recall to patients who are due, with a line about checking their sun protection, primes the conversation before they’re even in the chair. Patients who’ve churned to the chains often come back for something specific and seasonal like this.
Make the advice standard, not optional. Agree a short script the whole team uses: what UV does, what to look for on a label (UV400, CE/UKCA), and that clear lenses can be protected too. When every patient hears the same clear message, your conversion stops depending on which optom or DO they happened to see.
Dispense properly. Match the recommendation to how the patient actually lives — driving, sport, kids, screen-heavy work — and record what you advised. If a patient declines now but burns their eyes on holiday in August, the note that you raised it matters, and it gives you a reason to follow up.
Where your practice management software does the lifting
A seasonal service only works if it runs the same way every time, and that’s a systems problem as much as a clinical one. This is where a modern PMS quietly earns its keep.
It starts with recall. The same engine that drives your routine reminders can run a targeted pre-summer prompt to the right patients — drivers, outdoor workers, parents, anyone you’ve previously flagged as interested in sun protection — without anyone building a list by hand. Tag patients in the patient record when UV comes up, note the advice you gave, and next year the system already knows who to nudge.
On the dispensing side, decent stock control stops the all-too-common situation where the sun comes out and your sunglasses range is thin, mismatched or full of last season’s frames. And when the till data flows into your billing and finance view, you can actually see what your sun and second-pair business is worth — which is the only way to know whether the effort is paying off and where to push next year. Raven Vision was built inside Shaukat’s own three practices for exactly this kind of join-up: the clinical note, the recall, the stock and the numbers all sitting in one place instead of four.
Five things to put in place this month
If you do nothing else before the summer peak passes, do these. First, agree a one-paragraph UV advice script so every patient hears the same thing. Second, audit your sunglasses and Rx-sun range — is there anything good to actually recommend? Third, add a UV or sun-protection flag to your patient records so you can build next year’s recall automatically. Fourth, brief the dispensing team that clear lenses can carry UV protection and that Category 4 isn’t for driving — two facts that change conversations. Fifth, send one pre-season recall to patients who are due, mentioning sun protection, and see what comes back.
Summer gives you a window where patients actually want to talk about their eyes and the sun. Most practices waste it answering one-off questions at the counter. The ones that treat UV as a proper clinical service — advised consistently, dispensed well, and recalled year after year — protect more patients and build a revenue stream that returns every single year.
If you’d like to see how Raven Vision handles the seasonal recall, patient flagging and dispensing visibility that make this work, book a quick demo or take a look at what’s included for £149 a month — no setup fee, no lock-in, and built by opticians who run their own practices.
