How Eyewear Sizing Works

Every pair of eyewear includes three measurements printed inside the temple arm. These numbers help you compare fit across different frames.

Example: 52–20–145

  • 52 mm — Lens Width
  • 20 mm — Bridge Width
  • 145 mm — Temple Length

Compare to a Pair You Already Own

Take any pair you like the fit of and check the numbers inside the temple. Compare them to the measurements on our product pages.

Lens Width

A difference of 1–3 mm will feel very similar. This is the primary number that affects overall frame size.

Bridge Width

A difference of 1–2 mm can noticeably change how the frame sits on your nose. This is the most important number for comfort.

Temple Length

This number matters the least for most people. A difference of 5 mm is usually unnoticeable.

Small Adjustments Are Always Possible

Acetate can be gently adjusted by most optical shops for a more tailored fit. A slight temple bend or nose‑bridge adjustment can fine‑tune comfort if needed.

EYRA was founded in Boston with a simple idea: premium sunglasses shouldn’t require a luxury markup. After 25 years working across global consumer goods and optical categories, we saw how much eyewear pricing was driven by branding, licensing, and marketing — not materials or craftsmanship.

Most sunglasses under $200 use low‑cost TAC or basic polycarbonate lenses. EYRA uses optical‑grade nylon polarized lenses, the same material found in luxury eyewear because it delivers sharper clarity, higher impact resistance, and true‑to‑life color. Nylon is lighter, stronger, and optically superior to TAC, making it the premium choice for long‑term durability and visual performance.

Our frames are crafted from hand‑finished acetate or stainless steel, engineered for balanced ergonomics and all‑day comfort. Every detail — from hinge construction to finishing — is designed with intention and built to last.

The result: luxury‑grade materials and optical performance, without the luxury markup. Designed in Boston. Built for clarity. Made to last.
