Adjust your tint the instant the light changes — with a twist.

Adjust your tint the instant the light changes — with a twist.
Powster makes the first sport sunglasses with instant, dial-controlled tint. No two-minute lag. No app. No swapping lenses. Just reach up, twist, and the light is exactly how you want it — for 21 days on a single charge.

The problem  —  your lenses can't keep up with the light

Every runner, rider and golfer knows the feeling. The light changes in a second — but your lenses take minutes. Today's photochromic lenses typically need around two full minutes to react, and they can only ever guess at the tint you actually want. In the outdoors, that lag isn't just annoying. It's dangerous, and it's slow.

On the trail

• You sprint from open sun into tree cover and the world goes black. For a critical few seconds you can't read the terrain — and that's how ankles get rolled.

Our sponsored athlete, Manuel Merillas and Meng Guangfu — top performing ultra runners in the world on ITRA — often won't even wear photochromic lenses into the trees. They push them up onto his forehead instead. The technology couldn't keep up with them. — Powster athlete team

Under hard sun

• When the tint maxes out, you can't read your watch or phone. You need to lift the tint for a moment — but you can't.

On the bike

• Tunnels come at speed. By the time a photochromic lens reacts, you're already back in the light.

On the course

• Facing the sun, then away; looking down the fairway, then at the tee. The light never settles, so a slow lens is never right.

On holiday

• Checking your phone in bright sun, or reading on the beach when the lenses are simply too dark to see the page.

The common thread: you never had control. Until now.

The solution  —  tint you control, instantly

Powster puts the tint in your hands with a signature dial on the temple. Twist it up to darken, down to brighten — and the lens responds almost instantly. No waiting for the lens to “decide.” No phone. No app. Just an instinctive, glove-friendly control you can use mid-stride, mid-climb, mid-swing.

How it works

• Twist to set. The dial drives the lens from clear to dark across the full range — and every shade in between. You choose the exact tint the moment you need it.
• Near-instant. The change happens in about a second, not two minutes — fast enough for tunnels, tree lines and cloud breaks.
• Stepless. It's not just “light or dark.” You can dial in precisely the level of tint that suits the conditions and your eyes.

Why electrochromic  —  the technology others don't have

Most “adjustable” electronic eyewear uses liquid-crystal (LCD) lenses. Powster is built on true electrochromic technology — an electrochemical lens that behaves like a flat, transparent solid-state film. That difference is the whole product:

• No liquid in the lens.  Nothing to swirl when pressed, nothing to leak, and no failure at altitude or under impact. It's a solid sheet, not a fluid cell.
• Sharp, distortion-free optics.  A flat solid-state film means clean, true vision edge to edge — not the haze or shimmer some electronic lenses show.
• Rugged by design.  Built to take the knocks of real training, not baby-ed on a shelf.

Built for the way you move

• Instant dial tint. Full clear-to-dark control, in about a second.
• 21 days on a charge. Charge it once and forget it for three weeks. And if the battery does run out, the lens holds its last tint — you're never left with a dead, useless lens on your face.
• Only 35 grams. About the same as a normal pair of sunglasses. You'll forget the tech is even there.
• Non-slip and rugged. Grippy temples and a durable frame that stays put when you're moving fast and sweating hard.

Where it shines

• Trail & hiking: stay in control through every tree line and cloud break — eyes on the terrain, always.
• Cycling & everyday driving: dial down before a tunnel, dial back after — on your terms.
• Golf: match the tint to every hole, every direction, every lie.
• Travel & everyday: lift the tint to read your phone in the sun or a book on the beach, then drop it back down.

Choose your style  —  and help us decide what to build

The Powster electrochromic engine and dial are identical across every frame. Only the look changes — so you get the same performance in the style that's you:

• Lifestyle. Clean, everyday sunglasses that happen to be smart. Wear them from the trailhead to the coffee shop.
• Sport Performance. A closer, wrapped fit with more coverage — built for race day and hard efforts.
• 90s run culture. A bold, retro-sport silhouette in the throwback style that's taking over run culture right now — fast, colourful, unmistakable.

Because we're a small team being careful with every dollar, we're letting backers choose which styles we produce. Back the frame you love. Any style that reaches its minimum order goes into production. If a style doesn't make it, you're never stuck — you can switch to the most-backed style or take a full refund, your call. It's your money and your face; you should decide.

Who's behind Powster

Powster has been building performance eyewear for outdoor people since 2020. We're not a gadget company that discovered sport — we're a sports-optics brand that got tired of lenses that couldn't keep up. Everything here comes from real problems our own team and our sponsored athletes hit in the mountains, on the road and on the course. We manufacture our own eyewear, which is how we can put breakthrough lens tech into a 35-gram frame at a price that isn't absurd.
