Frequently asked questions
Help with frame size, materials and lenses.
Compare the measurements with glasses that fit you well. For example, 52–18–140 means lens width, bridge width and temple length, in millimetres. These measurements are a guide; the frame shape and bridge fit also matter. If you are unsure between sizes, ask us before ordering.
Compare the materials, weight and fit in each model’s details. Acetate, metal and injected materials can feel different; no material is the best choice for everyone. We can help you choose for your intended use and preferences.
The category describes how much visible light the lens lets through, from 0 (very light) to 4 (very dark). It is separate from UV protection. Check the manufacturer’s information for each model; category 4 lenses are not suitable for driving.
Explore the catalogue by brand and compare each model’s shapes and colours. Availability varies by reference; the product page shows the options you can choose.
Fit, frame material, lens features and the model’s warranty. Price alone does not tell you the level of UV protection. Check the product and manufacturer specifications, and ask us if you need to confirm a detail before buying.
