Frame & Lens Guide

Choose eyewear by the details of the specific frame and lens combination, not by a general promise that every model is built the same way.

Frame construction

Materials, hinges, nose pads and temple designs vary between models. Check the product information for the pair you are considering, and ask our team to confirm any detail that matters to you. Do not assume that a feature described for one model applies to another.

Lens choices

Frame color and lens type can be linked within a product's available options. Select the complete frame-and-lens combination before comparing photographs or ordering. A mirror finish, tint name or frame color alone does not establish the lens's polarization or light category.

Fit comes first

Compare measurements with glasses you already find comfortable. Our fit and measurement guide explains lens width, bridge width, temple length and other fit considerations.

Confirm the specifications you need

For product-specific material, lens, testing or intended-use questions, contact Orders@CassetteOptics.com before ordering. Include the model and exact color/lens option.
