If you do not select a pair of glasses without measuring, it will cause difficulties in the use of glasses in the future. For example, the selection width is too small. The frame will be easy to 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 contains the frame. **Nose bridge width**: Frame width on the bridge of the nose. **Lens width**: Does not include the width of the lens itself. **Lens height**: The highest point to the lowest point of the lens. **Tripod length**: Frames without lenses are not included, and the seams of the temples begin to be measured at 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**With the**leg length**larger style. When we open the glasses, there will always be a number on the inside of the temples, for example:**54□18-136** 54 represents the lens width, 18 represents the nose width, and 136 represents the length of the tripod, and the unit is mm. The total face width can be measured by itself or by the mirror width X 2 + nose width. Therefore, as long as the measurement according to the above size specifications, or take out the old glasses measurement that you wear comfortable, plus the tolerance of +/- 3, you can choose the frame size that suits you. The framed glasses will be marked with a size description to make it easier to choose!
