The frame size is determined by measuring the total width of the frame from one hinge to the other, ensuring a precise fit for your face.
Frame Size Guide by Lens Width
The frame size is based on the width of a single lens, measured horizontally at its widest point, as typically indicated on the inside of the temple arm.
Estimate Your Ideal Frame Width
1.Grab a Credit Card: Use any credit card you have handy.
2.Position the Card: Hold the card under one of your eyes, aligning the long edge with the center of your nose.
3.Check the Length: Look at how far the card extends beneath your eye.
Narrow
If the edge of the card goes past the edge of your eye, you should look for smaller frames with narrower lenses.
Medium
If the edge of the card lines up right at the edge of your eye, a medium-sized frame will probably work well for you.
Wide
If the card doesn’t reach the edge of your eye, consider trying on larger frames with wider lenses.
