What are aspheric lenses?  

The surface radian of aspherical lens is different from that of ordinary spherical lens. In order to pursue the thinness of lens, the surface of aspherical lens needs to be changed. In the past, spherical design was used to increase the aberration and deformation, resulting in obvious bad phenomena such as unclear image, distorted horizon and narrow field of vision.  Now the aspheric surface design corrects the image, solves problems such as distorted horizon, and makes the lens lighter, thinner and flatter.  And still maintain excellent impact resistance, so that the wearer safe use.  

One.The aspherical lens is light and thin, with small edge aberration, wide field of vision and real and clear imaging.

2.  More relaxed  

     You can hardly feel the presence of aspherical lenses when you wear them, and they will help your eyes lose weight. Enjoy the ease and casualness they bring to you.  

3 . More natural
Aspherical design, more natural, less visual deformation, visual objects more realistic.

4 . Easier to clean and oil resistant

Characteristics of progressive tablets

Designed to provide a natural, convenient and comfortable correction for presbyopia patients, wearing progressive lenses is like using a video camera. A pair of glasses can see at a distance, close to home, as well as middle-distance objects. So we also describe progressive lenses as "zoom lenses", after wearing a pair of glasses is like a pair of glasses.
