About spherical lenses

 Aspheres are more realistic than spherical images and can be more expensive than spherical ones. Glass sheet: very heavy, easily broken, easily scratched when broken, but made a little thinner than resin sheet.. Usually the height is chosen. Resin piece: light, not easy to break, PC piece: not broken, suitable for no frame. These are the refractive index, which will affect the thickness and hardness of the Glasses Lens Index. The higher you go, the thinner you get. But not the only factor... In addition to refractive index, the thickness of the Cat Eye Reading Glasses lens should be determined by the size of the Cat Eye Eyeglasses lens frame and whether the pupil distance is close to the center distance of the lens frame (the closer it is, the thinner it is).
