Help identify your sunglass model

It is better to put less information in the search bar than more. We keep lens information at model level. We don't keep all subsequent numbers that represent every lens combination and frame color.

Ray Ban, Prada and Persol will all have the RB #### number on their arm. Use our lens search engine to find #### numbers. It will often display several models and a sample frame image.

It is crucial to get the right lens width. Your sunglasses will have two numbers before the small square. You can also manually measure the width of your lens.

The same model is available in different sizes by many brands. The Ray Ban Aviator Large Metal sunglasses, for example, all have the model number RB3025LM. They are available in three sizes: 55mm, 56mm and 62mm.


Manually measuring the size of lenses

One lens should be measured at its widest point. Measure as the crow flies and not along the lens curve. Allow 1-2mm to the lens below the rim. Keep in mind that most sunglasses have writing under the nose bridge or on the inside left arms. This is far more precise than a manual measurement.

Millimeters are the Industry Standard for lenses. Convert inches by changing the decimal to inches and multiplying by 25, A 2x7/8 inch lens is converted to 2.875 inches by multiplying 25.4 with 73mm.
