The lenses were made of a plastic polymer called CR-39, because it was the 39th formulation of a thermal-cured plastic developed by PPG Industries in the early 1940s. Plastic lenses are light and low cost.
Polycarbonate lenses: polycarbonate lenses were first introduced in the 1970s and they have become increasingly popular anad remained for a long time.

The height of the nose pad is adjusted by first holding the glasses with one hand and holding the nose pad with pliers with the other. Then the pliers are lifted up and the nose pad is moved down until the glasses are in the correct position on the face. The asymmetrical adjustment method is to first hold the frame of the eyeglasses with one hand, the other hand clamps the nasal plate with pliers. Then twist it in the direction of the correct tray position so that the surface of the tray is in contact with the two sides of the nose. Wrap one side of the lens of the glasses to be operated with a cloth first to prevent the screwdriver from slipping and scraping the lens during the operation.

What are acetate glasses?
Acetate spectacle frames are the most common spectacle frames on the market. It has a light texture and good gloss, which is very popular among young men and women. Acetate frames are lighter and generally considered to be better than plastic frames. Acetate fiberboard is known for its Hypo-Allergenic, so it is a popular choice for people with sensitive skin. Unlike some plastic or metal frames, they can cause allergic reactions. However, you will find that acetate frames are usually more expensive than ordinary plastic frames. So what is the reason?
Acetate is one of the first synthetic fibers. It was not used to make glasses until the late 1940s. The higher the quality of acetate, the better the gloss and transparency. Not easy to burn is one of the biggest characteristics of acetate fiber. Also because of the non-combustibility of acetate fiber, this material can hardly be affected by ultraviolet radiation to change color, and can better maintain the gloss of the spectacle frame. Moreover, it is light and hard, and it is not easy to deform.
What are nose pads?
Nose pads include stipule stalk, stipule boxes, and stipules. The stipules are in direct contact with the nose and play a role in supporting and stabilizing the frame. Certain molded plastic frames may not have stipules and stipule boxes, and the stipules are connected to the mirror ring.
In fact, when designing different materials and different styles, the designer will judge whether nose pads are needed according to the comfort and aesthetics of the glasses. Generally, metal frames are equipped with nose pads, and the nose pads are movable in order to adapt to various nose shapes. Metal frames with nose pads can prevent some people's skin from being allergic to metal. On the other hand, metal looks more rigid and business, and adding nose pads is more beautiful and comfortable. Most glasses without nose pads are sheet-framed glasses. The sheet material is relatively light and non-allergenic. In terms of aesthetics and comfort, no nose pads are more suitable.
