The Features

A lens you control, not the sun

01
Eclipse™ Instant Tint

Slide the right temple and the lens shifts — four levels, 54%–17% VLT, in 0.1 seconds. It’s the kind of control Patrick insisted on: no waiting, no lens swaps, no losing the point to the light.

02
High-Contrast Tennis Lens

A tennis-tuned, high-contrast lens with a blue Revo mirror finish sharpens the ball against court surfaces and LED backdrops, so you track it earlier.

03
Anti-Fog, Sweat-Shedding Coatings

Hydrophobic, oleophobic and interior anti-fog coatings shed sweat and resist fog through the longest, hottest rallies.

04
Locked-In Performance Fit

A lightweight shield frame with grippy ear tips and a slim, near-invisible nose piece — built to stay put through every change of direction.


05
Not Photochromic, Better

Photochromic lenses react to UV on their own schedule. Ace puts the lens under the player’s control instead — it works under floodlights, in cloud, and at the exact moment you need it.

FAQs

  • How does Ace’s tint control work?

    Slide the right temple and the lens moves across four levels, from 54% to 17% VLT, in 0.1 seconds. Darker into the sun, lighter with it behind you — your choice, mid-match.

  • Is Ace photochromic?

    No — and that’s the point. Photochromic lenses react to UV on their own schedule and lag incloud or under floodlights. Ace puts the lens under your control instead, so it changes theinstant you need it to.

  • Is Ace polarized?

    No, Ace is not polarized.

  • Is Ace waterproof?

    Ace carries an IPX4 water resistance rating for sweat and splash protection, and the lens coatings are hydrophobic, oleophobic, and interior anti-fog.

  • How long does the battery last?

    Up to 52 hours of continuous tint-adjustment use (up to 70 hours per charge), with a full chargein under 1 hour via the magnetic pogo-pin cable.

  • Does Ace have audio or a voice assistant?

    No — Ace is tint-only, with no speakers or microphones. (That’s The Coach’s role in the Mouratoglou Collection.)

  • Do you offer a guarantee?

    Yes — a 30-day money-back guarantee and a 1-year warranty on every pair of Ace.

I usually avoid wearing sunglasses when I play because they either fog, slip, or feel too dark once the sun moves. Ace feels different. The tint shift is instant, and being able to go darker when serving into the sun and lighter in the shade is genuinely useful. The lens contrast also makes the ball feel easier to pick up, especially on bright courts.

You can tell these were designed around real on-court problems. They stayed locked in through movement, didn’t fog up during long rallies, and the tint control made a big difference when switching ends. I also like that they’re not photochromic — I don’t have to wait for the lens to decide. I control it when I need it.

Bianca
Verified Review

The biggest surprise was how natural they felt once I started playing. They’re light, secure, and the tint adjustment is fast enough that it doesn’t distract from the match. The high-contrast lens helps the ball stand out, and sweat didn’t smear across the lens like my usual sunglasses. It feels like eyewear made for tennis, not just adapted for it.
