Adjustment of the angle of the nose pad
For the angle of the nose pad, you can apply torque in the horizontal or vertical direction according to the deformation needs. It can be held in the proper part of the nose pad with needle-nose pliers, and the torque can be applied at a certain angle in the vertical plane or horizontal plane to achieve the purpose in accordance with the deformation needs. In the time of repeated actions, in order to prevent the welding place of the nose pad and the glasses ring from breaking due to repeated stress deformation, you can use your fingers to apply external force at the welding place to change the deformation position and play the purpose of protection.
The glasses are stylish and have a personality, and the shop decoration has a designer style. A combination of fashion and business, the nose pads are designed with water droplets that are more suited to Asian faces.

What is an aspheric lens?
Strictly speaking, any lens with a refractive surface that is not a sphere is an aspheric lens, including ordinary astigmatism lens, progressive multi-focal lens, Aspheric apical lens, etc. But customarily, our daily aspheric lens refers to the Aspheric apical lens. From the center of the lens to the periphery, the radius of curvature increases (the surface of the lens flattens out).
Although glasses are the tool that corrects myopia, a lot of people like to dress up fashion with it now.

What is a progressive lens?
A progressive lens is a lens whose upper sides are used to see far, and the lower side is used to see near. The distance from the fixed distance power above the lens to the near power fixed below the lens does not change suddenly, but a gradual transition between the two through the gradual change in refractive power.
Standard progressive lenses are multifocal lenses with three observation areas, farsightedness, intermediate vision, and nearsightedness. Unlike bifocals, there are no visible lines between each viewing area. They have a seamless, invisible design, where the optical power changes 'gradually' throughout the lens. Many people confuse 'bifocal' or 'trifocal' with 'progressive' but remember that bifocals and trifocals have visible lines in the lens, while progressive lenses do not. Because progressive lenses have no lines in the lens, they are more popular multifocal lenses than bifocal lenses. However, is progressive lens good for eyes?
