Protect Your Eyes on the Water: Surfer's Eye, UV Damage & Floating Sunglasses

A while back my optician flagged UV damage in my eyes and told me, in no uncertain terms, to sort my eye protection out. That got me actually reading up on what all those hours on the water — wind in your face, sun bouncing off the water twice as hard as it does on land — are doing to your eyes long-term. It's the same UV bounce that skiers get off snow, except we get it off the sea, all season.

This isn't just a windsurfing thing either. Kitesurfers, wingers, SUP paddlers, dinghy sailors, kayakers — anyone spending hours squinting into reflected glare and salt spray is in the same boat (sorry). So here's what surfer's eye actually is, why contact lenses and open water are a genuinely risky combination, and what we'd actually recommend — including what we stock in the shop.

What is “surfer's eye”?

The proper name is pterygium — a fleshy, pinkish growth of tissue that creeps across the white of the eye, and eventually the cornea if it's left unchecked. It's caused by chronic exposure to UV light, wind and dust, which is exactly the combination you get on a beach or on the water. It often starts as a smaller yellowish bump called a pinguecula, and it builds up slowly over years rather than appearing after one bad session.

Symptoms range from mild irritation, redness and a permanent feeling of grit in the eye, through to blurred vision if it grows over the cornea. There's also photokeratitis — sunburn of the eye — which is the acute version: a single day of intense reflected UV (think a bright day on open water, or snow) can leave your eyes red, watering and painful by the evening, even without a chronic pterygium developing.

Treatment for pterygium ranges from lubricating drops for mild cases to surgical removal if it's affecting your vision — and it can grow back. Prevention is genuinely the easier route: proper wraparound sunglasses with full UV protection, worn every time you're out, not just on the sunny days.

Contact lenses and open water don't mix

If you wear contacts to windsurf, kitesurf, wing or paddle, there's a second risk that's got nothing to do with UV: Acanthamoeba keratitis. Acanthamoeba is a tiny organism that lives in tap water, lakes, rivers and the sea. Soft lenses can trap it against the cornea, and any micro-abrasion from sand or salt gives it a way in. It's rare, but it's a genuinely nasty infection — often painful, slow to treat, and in the worst cases it costs people their sight in that eye.

The rule we stick to: any lenses that have been in the sea come out straight after the session and go in the bin, no exceptions, no "they still feel fine so I'll get one more day out of them." If you're buying lenses pay-as-you-go for exactly this reason (worn a few times a week rather than daily, so a subscription doesn't make sense), it's genuinely cheaper to treat them as disposable around watersports than to risk it. Pack some preservative-free lubricating drops too — wind and salt dry your eyes out fast, on the water or at a festival, and a good flush at the end of the day makes a real difference.

Two routes to sorting your eyewear

Route one — invest in a dedicated prescription pair. Custom scripts wrapped around curved sports frames need proper lab work, so these don't come cheap, but if you're on the water most weeks it's worth it. Our own pick is Bollé — the Airfin and Airdrift both use Bollé's own Air Float technology, so they float horizontally if you come off, rather than sinking straight to the bottom. They're available prescription-glazed through UK opticians and specialists like RxSport. SunGod (a British brand) do a very popular Renegade that a lot of windsurfers rate, though it doesn't float natively — you'll want a Chums retainer or a neck strap with it. Waterhaul, made in Cornwall from recycled fishing net, is a solid UK eco option too, same story on the float.

Route two — contacts (or your everyday glasses) plus a cheap floating pair. If you're not on the water constantly, this is the one we'd point most people to. Wear your contacts (thrown away straight after, as above) or your normal specs on a retainer, and keep a pair of proper non-prescription floating sunglasses in the boat bag for the glare. Our Dirty Dog Wetglass Curl II floats, has a hydrophobic coating so rain and spray bead straight off, and is polarised to cut glare off the water. It's not available with a prescription off the shelf, but any high-street optician can lab-fit prescription lenses into a frame like this — worth asking about if you'd rather keep the frame you already like the look of. If a wave takes them, you're not out £160+.

Either way, a retainer earns its keep. Chums do one that's specifically designed to float your glasses if they come off — genuinely useful if you're not ready to commit to a native-floating frame yet, or you just want backup for your normal sunglasses.

FAQs

What is surfer's eye?

It's the common name for pterygium, a fleshy growth on the eye caused by long-term exposure to UV, wind and dust — the exact conditions you get on the water. It builds up over years, not overnight.

Can I wear contact lenses windsurfing or kitesurfing?

You can, but treat any lenses that touch sea water as single-use — take them out and bin them straight after the session. Reusing lenses that have been in open water is the main way people pick up Acanthamoeba keratitis, a serious eye infection.

Do I need prescription sunglasses for watersports?

Not necessarily. If you're out most weeks, a dedicated Rx pair is worth the investment. If you're more occasional, contacts (or a retainer on your normal glasses) plus a cheap non-prescription floating pair covers you for a fraction of the price.

What UV rating should I look for?

Look for 100% UVA/UVB protection or a UV400 rating — anything less isn't doing the job. Polarisation isn't the same thing as UV protection; it cuts glare, so ideally you want both.

Do floating sunglasses need to be polarised?

They don't have to be, but on the water we'd always recommend it — polarised lenses cut the horizontal glare bouncing off the surface, which makes a real difference to how long you can comfortably keep your eyes open out there.
