Understanding Lens Size: What Does 64mm Mean?

The 64mm lens size in men’s sunglasses refers to the width of each lens from end to end. This critical measurement determines how large the lenses are and how they fit your face.

Lens Width (64mm) – The horizontal measurement of one lens.
Bridge Width – The gap between the lenses, usually 14mm–20mm.
