Choosing the right size is easy. Start with the curvature of your chosen frame. Most of our frames have 4-base curvature to maximize the range of prescriptions that work with them. In the picture below, the frame with 6-base curvature has a much higher “wrap angle” to provide optimal coverage, and you’ll find it in designs like our Active Collection of Crosslink™ frames. Once you have the curvature, use the chart to get the number range for your face size.

Face Size
Extra Small Small Medium Large Extra Large
4-Base Curvature 48-49 50-51 52-53 54-55 56-57
6-Base Curvature N/A 51-52 53-54 55-56 57-60
