As the name implies, the surface curvature of an Aspheric Lens is different from that of ordinary spherical lenses. In order to pursue the thinness of the lens, the curved surface of the lens needs to be changed. In the past, the spherical design was used to increase the aberration and distortion, resulting in obvious image blur. Distorted vision, narrow vision, and other undesirable phenomena. The current aspheric design corrects the image, solves the problem of distortion of the horizon, and makes the lens lighter, thinner, and flatter. And still maintain excellent impact resistance, so that the wearer can use it safely.

Imagine that we have a round transparent sphere in front of us. The surface of the sphere is a curved surface. This curved surface is called a spherical surface. Spherical Lens simply means choosing one of the surfaces of the sphere as the lens.
When you see things around the spherical lens, there will be distortions, while the aspheric design of the non-spherical lens can reduce the edge difference of the lens to a minimum, and see objects more naturally, with less distortion and more lifelike.
1. Clearer: The aspheric lens with unique coating treatment has perfect visual performance and presents clearer and comfortable visual effects.
2. Easier: After wearing aspherical lenses, you can hardly feel its existence. It will lose weight for your eyes and enjoy the ease and freedom it brings you.
3. More natural: The aspheric design is more natural, with less visual distortion and more realistic vision.
Aspheric lenses are so good, so why do people choose spherical lenses? Spherical Lens Suppliers told us that for friends with mild myopia, wearing spherical lenses and aspherical lenses are similar, there is basically no problem of aberration, and the lens thickness is similar. Considering the price factor, you can choose spherical lenses. In addition, for a very small number of people who are particularly sensitive to colors, such as those who wear aspherical lenses and feel rainbow phenomenon, you can try to replace spherical lenses.
