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.

Can lens thickness affect eyeglasses definition?
The lens thickness of myopic glasses will not affect definition, so you can choose the glasses with appropriate degrees according to your own situation. It is recommended to choose the lens with a membrane, which can increase the transmittance and can play the effect of anti-ultraviolet and waterproof functions. The thickness of the lens is related to the refractive index of the material used in the lens. The higher the refractive index of the lens, the thinner it is. The so-called ultra-thin lens is the lens with a high refractive index. From the side view of the lens, there will be a fuzzy color phenomenon. Because the nearsighted lens is a concave lens, and the edge is similar to a prism, which can produce a prism effect. In addition, when you wear glasses, try to choose a smaller frame, so you can avoid the prism effect on the edge of the lens.
