NOS, or "new old stock", the frames have never had lenses and are ready for your Rx or sunglasses. As always, adjustment by your optician may be necessary for a perfect fit. As a side note, I've always thought white frames look STUNNING as sunglasses, and these would be no exception!
The measurements are:
Hinge to hinge - 4 7/8"
Inside temple to temple - 4 15/16"
Across front - 5 1/4"
Temple length - 5 1/2"
lens width - 44 mm
bridge - 20 mm
These would be considered a size medium - you can compare these measurements to your own glasses to see if they would be a fit.
HOW TO MEASURE GLASSES:
The lens width is taken horizontally across the lens at the widest point, and the bridge width is the measurement across the bridge from one lens to the other. While each number is important on it's own in terms of how the lenses are centered over your eyes, adding the together gives you a general idea of how big the frames are. For instance, I wear a 46/22 in a cat eye frame, which added together is a 68, making them a medium to medium large. If you're a person who needs a large frame, try to find one with a combined measurement as close to 70 as possible; a small frame would be closer to a combined measurement of 60 or 62.
*Another measurement is the "PD" or pupil distance; this is the approximate length in mm from center to center of each lens. You can measure your own pupil distance in the mirror with a ruler, or measure an existing pair of frames that look good on you. While your eyes don't have to be exactly centered in each lens, try to get it close. .
