If you choose any pair of glasses without measuring, it will cause difficulties in using the glasses in the future, such as choosing too small a width The frame will easily break. 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 without lenses, the seams of 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**Large style with**Tripod length**. When we open the glasses, there is often a number on the inside of the temple, for example:**54 □ 18-136** Among them, 54 represents the width of the lens, 18 represents the width of the bridge of the nose, and 136 represents the length of the tripod. The unit is mm. The total surface width can be measured by yourself or approximated by the mirror width X 2 + the width of the nose bridge. Therefore, as long as you measure according to the above size instructions, or take out the old glasses that you are comfortable wearing, plus the tolerance of +/- 3, you can choose the frame size that suits you. Framed glasses are marked with size descriptions, making it easier for you to choose!
