Eyewear for watersports has a different job than a regular pair: kill the glare bouncing off the surface, and stay put when things get fast. That takes polarized lenses and a fit that does not give.
Shop nowWater reflects light horizontally, and that is exactly the glare your eyes squint against. A polarized lens filters that reflection out, so you see the chop, the gusts on the water and your line again. On top of that, temples on a regular pair slide the moment speed, spray or a knock is involved — in watersports how it stays on matters as much as the lens.
Four things. Polarized, for the glare. UV400 for full UVA and UVB protection, because on the water the sun reaches you from two directions. An adjustable strap or a wrap-around shape that stays put. And a frame that handles salt water — Glogglz models have saltwater-resistant nose rubbers and are tested in the sea, not only in a lab.
The Finz is the polarized sports sunglass with an adjustable strap and butterfly clasp: kitesurfing, windsurfing, wing foiling — anything where you get wet and the pair cannot go missing. The Rayz is the lightweight wrap-around, good when you spend more time above the water than in it: sailing, SUP, and cycling or golf too. The Cudaz is not a sunglass but a 2-in-1 swim goggle with UV400 and anti-fog, for when you go under: triathlon and open-water swimming.
Rinse with clean water after salt or chlorine and let it air-dry; don't rub it dry, that is what wrecks coatings. A protective hardcase is included free with every pair.
