Let's first understand the important dimensions of the frame: https://farm5.staticflickr.com/4850/32203446958_7d8537c5da_o_d.jpg **Overall width**: The total width of the glasses includes the frame. **Nose bridge width**: The width of the frame on the bridge of the nose. **Lens width**: The width of the lens itself without the frame. **Lens height**: The highest point to the lowest point of the lens. **Tripod length**: Frames that do not include lenses, the seams at the temples start to the bottom. Wherein**High lens width**smaller, relatively thinner lens, a high number of lenses are worried that if too thick, the proposed lens is selected from the aspect of smaller models; head circumference greater is recommended selected from**Total wide**and**stand long**larger models. When we open the glasses, there is often a number on the inside of the temple, for example:**54 □ 18-136** Among them, 54 is the width of the lens, 18 is the width of the bridge of the nose, and 136 is the length of the tripod. The unit is mm. The total face width can be measured by yourself or approximated by the mirror width X 2 + the width of the bridge of the nose.
