As an FYI, most sunglasses have the size written on the inside of one of the temples. The eye/lens size is first, then the bridge size, and then the temple (arm) size. To see what size you are, grab a ruler, look in the mirror, and measure your face, temple to temple. Sunglasses measurements are taken in millimeters, so you’ll need to convert. Your face width should roughly measure out to the width of the lenses and the bridge.
