OAKLEY PRESCRIPTION FRAME SIZE CHART

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
