Spherical lens
Aug 23, 2018

Aspherical lens

The surface curvature of the aspherical lens is different from that of the ordinary spherical lens. In order to pursue the thinness of the lens, it is necessary to change the curved surface of the lens. In the past, the spherical design was used to increase the aberration and deformation, and the apparent image was unclear, and the horizon was distorted. The narrow vision and other undesirable phenomena, in the aspheric design, corrected the image, solved the problem of distortion of the horizon, and at the same time made the lens lighter, thinner and flatter. Moreover, it still maintains excellent impact resistance for safe wearer wear.


Spherical lens

Conventional spherical lenses, which have distortion of the object around the lens, limit the wearer's field of vision.
