The glasses without the nose brace are plate glasses. In reality, there is still a nose pad, but it is relatively small and it's part of the frame. The westerners have high nose bridges, and many glasses have no or very small nose pads. For example, Harry Potter's glasses have no nose pads. European and American brands will change their nose pads for the Asian market. Eyeglasses without a nose pad rely on the bridge of the nose to support the center beam. It's hard for Asians to stand up, and their eyes are more protruding than sunken like westerners. Glasses are usually demanded to keep a 12mm distance between the lens and the eyeball, otherwise, the optical performance will have a great impact.

This is the use of diamond high perspective reflection film technology, in the lens to add color and film layer, in order to maximize the brightness of the object being seen. It is to compensate for the light for driving, which makes light pass through your eye. It can increase the three-dimensional sense of objects, making the line of sight more clear, to avoid confusion caused by blinding headlights.
