Eyeglasses in the market can be mainly categorized into three groups, namely, rimmed glasses (framed glasses), semi-rimless glasses and rimless glasses, if seen from the perspective of frames. Theoretically speaking, the first glasses are some of the earliest and oldest ones in the industry, with almost the same history as the first eye glasses several hundred years ago. By and large, rimmed eyeglasses take the largest market share in the field, though the other two are also very popular.
