Reading glasses should fit comfortably on a person’s face. If the glasses are uncomfortable the person may not wear them, and they may slip and/or fall off.
Standard reading glasses do not usually have any adjustment, and therefore to get the best fit, you will need to select the most appropriate size of frame for the person.
要选择最适合每个人的镜架尺寸，您需要了解有哪些镜架尺寸可供选择。本模块第一课已对此进行了介绍。

Frame width: No wider than the overall width of the person’s face. If too wide or too narrow, the temples will not sit comfortably on the side of the person’s face.
