If you choose a pair of glasses without measurement, it will cause difficulties in using glasses in the future, such as choosing a too small 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 **Total Width**: The total width of the glasses includes the frame. **Nose Bridge Width**: The width of the frame on the nose bridge. **Lens Width**: Does not include the width of the lens itself of the frame. **Lens Height**: The highest point to the lowest point of the lens. **Tripod Length**: The frame does not include the lens, and the seam of the temple is measured to the bottom. Among them, the smaller the**lens height and width**, the thinner the lens is. If you are worried about the thickness of the lens, it is recommended to choose a style with a smaller lens height and width; for a larger head circumference, it is recommended to choose**total width**Larger style with**tripod length**. When we open the glasses, there is often a number on the inside of the temples, for example:**54□18-136** 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 through 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 your comfortable old glasses for measurement, plus the allowable value of +/- 3, you can choose the frame size that suits you. Framed glasses will be marked with size instructions, making it easier for you to choose!
