Lenses can come in all sorts of shapes, square, round, oval, pear-shaped, and so on, so it's often difficult to judge the actual look of the lens from this figure. The lens diameter is the width of the lens at its widest point, measured in a straight line, not following any lens curvature. In any event, the first number (in millimetres) is the lens diameter, the second is the width of the bridge, and the third (if any) is the length of the temple arms.
The numbers can be separated by a small rectangle like this 50 �-� 22 or divided with a pipe like this 56|16|125. Lens sizes are typically aligned with the bridge size and sometimes with the arm length.
