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.
