A well-fitting frame should feel secure and comfortable while positioning the lenses correctly in front of your eyes.
Understanding Frame Measurements
Typical measurements include lens width, bridge width and temple length. These numbers are useful, but they do not tell the whole fit story.
Bridge and Nose Fit
The bridge should sit securely without excessive pressure or sliding.
Temple and Frame Width
The frame should not squeeze the sides of the head or sit excessively wide.
Lens Position Matters Too
For prescription lenses, especially progressives or stronger powers, how the frame positions the lenses is important.
Frequently Asked Questions
How do I know my glasses size?
Check the markings on an existing well-fitting frame and compare them with professional fitting.
Can two frames with the same size fit differently?
Yes. Shape, bridge design, material and temple geometry can all change the fit.
