How do I know what size glasses frame I need?
With unified factory product size, why others can wear without problems, but there is a problem when I wear the glasses? There are differences between the contours of each person's face, including factors such as the width of the head, the distance between the ears and the corners of the eyes as the crow flies, the thickness of the bridge of the nose, and so on, which involves ergonomics. But there is one thing we can agree on. When people with the same ear distance wear the same type of glasses, they have different feelings, even if the arm length of the glasses is the same. People with fatter faces will feel uncomfortable.

It is very simple to solve this problem. You need to look at a variety of parameters in the frame of the glasses, including the total width of the frame, the length of the arm. These parameters will be reflected in a qualified spectacle frame.
