The build is the point.

Slate is built around a simple standard: exact materials, quiet design, and one honest price. Every frame comes with Studio Acetate, SlateShield lenses, and 5-Point Flex hinges.

One standard on every pair. No upgrade maze.

Material System

The details that need to be seen.

Frame, lens, and hinge are separate standards, so each gets its own close-up: acetate depth, coated lens performance, then hinge construction.

Mazzucchelli acetate earns the close-up.

Studio Acetate uses hand-cut Mazzucchelli sheets, not generic injected plastic. The material is known for durability, flexibility, hypoallergenic comfort, and color depth that can be polished instead of painted over.

The lens stack works in daily light.

SlateShield is the coated lens system: polarized polycarbonate for lighter, impact-resistant wear, an anti-reflective back coat to reduce bounce-back glare, plus hydrophobic and oleophobic layers that help shed water and fingerprints.

The hinge carries the fit.

The hinge is where quiet design becomes mechanical confidence: spring-loaded flex, stainless steel hardware, and a smoother open-close feel that supports daily wear.

Premium should be easy to verify.

You should not have to decode a spec sheet or wait for an upgrade prompt. Slate keeps the material floor visible.

Designed for close inspection

The quiet parts still have to earn attention.

Slate does not rely on loud logos or trend churn. The frame has to make its case up close: acetate depth, hinge action, lens clarity, and a finish that feels intentional in hand.

Care

Keep the materials doing their job.

Better materials do not need complicated maintenance. They need a simple rhythm: rinse grit away, clean with microfiber, and store the frame when it is not being worn.

  • Rinse firstSalt, dust, and grit can scratch a lens before a cloth ever helps. Rinse debris away, then wipe.
  • Use microfiberKeep a clean microfiber cloth in the case and skip paper towels, shirt hems, and dry rubbing.
  • Case themAcetate and coatings hold up better when the frames are not loose in a bag, console, or pocket.
