If you choose any pair of glasses without measuring, it will cause difficulties in the use of glasses in the future, such as choosing a width that is too small Frame will easily break. Let’s first understand the important dimensions of the frame: https://farm5.staticflickr.com/4850/32203446958_7d8537c5da_o_d.jpg **Total face width**: The total width of the glasses includes the frame. **Bridge width**: The width of the frame on the bridge. **Lens width**: The width of the lens itself without the frame. **Lens high**: the highest point to the lowest point of the lens. **Leg length**: The frame of the lens is not included, the seam of the temple begins to measure 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**leg length**. When we open the glasses, there will often be a number on the inside of the temple, for example:**54□18-136** Among them, 54 represents lens width, 18 represents nose bridge width, and 136 represents tripod length in mm. The total face width can be measured by yourself or approximated by the mirror width X 2 + nose bridge width. Therefore, as long as you measure according to the above size instructions, or take out the old glasses that you wear comfortably, plus the tolerance of +/- 3, you can choose the frame size that suits you. The framed glasses will be marked with size instructions, making it easier for you to choose!
