1. Determine the eye size
"
A measurement"
of your
glasses. The eye size will be printed on the inside of either temple
arm or the inside of the bridge. It
is typically followed by a box or a dash with the next number indicating
the bridge width. In the example above,
the eye size is 50 and the bridge is 18. either 50[]18 or 50-18 would
be printed on the glasses. If it unreadable, measure across the lens of
one eye at its widest part. The 140 in the example is the temple
arm length and not used in clip-on fit.
2. With most metal frames, a clip-on one size large than
your frame - in this example 52 in the correct shape - will provide the best fit.
3. To determine
the correct shape, measure your glasses with a metric ruler from the top of the frame to the bottom.
This is the "
B measurement."
4. Compare your A and B measurement to the charts for the basic shape of your glasses to
determine the best fit. The bridge distance.
is not critical since the glide clip-on will adjust to different size bridges.
5.
Click on the image of the lens shape that best matches your glasses to print the measurement template.
Make sure your printer settings are set to 100%, actual size, no scaling
of size. Print the templates, use your ruler against the ruler image
to verify the template printed the correct size, and verify the fit
against the template. Sometimes a different shape will provide a better
fit.
