Your 3-step guide to identifying any sunglass model

Locating your model number is simpler than it looks. Use our step-by-step guide below to find the details printed on your frame.

Step 01

Find the brand or model name

First, look for a logo or brand name somewhere on the frame. Many sunglasses also carry a separate model name, usually printed on the inside of the temple arm. For instance, Ray-Ban is the brand, while Wayfarer is the model.

Step 02

Find the model number

The model number is usually stamped on the inside of the temple arm or across the bridge. It typically opens with a couple of letters — 'RB' for Ray-Ban, 'OO' for Oakley — followed by a run of digits.

Step 03

Work out your lens width

That run of digits usually covers lens width, bridge width, and temple length in one string. For example, '54□16 140' breaks down to a 54mm lens, 16mm bridge, and 140mm temple. It's the first number, the lens width, that matters most for a replacement lens order. Brands like Persol, Prada, and Ray-Ban often reuse a model number across several different sizes, so don't assume — check this figure carefully.
