Eyewear Sizing Guide

EYEWEAR SIZING GUIDES
To choose the right size for your eyewear, refer to the sizing information found on a comfortable pair of glasses that fit you correctly and that you already own.
In most cases, you will find the size of the lenses, temples and bridge in the inner part of the temples or the bridge. If they are not there, you can verify these measurements with a measuring tape.
Order your eyewear in a size as close as possible to these measurements.
Please note that optical glasses are considered a medical device and cannot be handled by our Cartier boutiques.

The lenses used for Cartier sunwear frames have been selected to ensure visual comfort and protection against sunlight, including ultraviolet light (UVA and UVB). Each frame has filters that protect against ultraviolet radiation, as indicated on the right-hand temple.
The majority of Cartier sunglasses are produced with category 2 or 3 lenses.
- Lenses category 2 – Light transmission: 19% - 43% , ensures good protection against solar glare, ideal for daily use in sunny or changeable weather.
- Lenses category 3 – Light transmission: 9% - 18% , ensures a high level of protection against solar glare, ideal for intense sunlight.
