Depending on model, the limit on prescription strength is as follows:

Full Carbon Frames:

Sphere: -6.00 to +3.00

Cylinder (Astigmatism): -2.00 to +2.00

Axis: 1 to 180

PD (Pupillary distance): 50-75

The combined sphere and cylinder powers should not be over -6.00

Titanium Frames:

Sphere: -8.00 to +4.00

Cylinder (Astigmatism): -2.00 to +2.00

Axis: 1 to 180

PD (Pupillary distance): 50-75

The combined sphere and cylinder powers should not be over -8.00
