● ASP lens:

 An aspheric lens or asphere is a lens whose surface profiles are not portions of a sph or cyl. In photography, a lens assembly that includes an aspheric element is often called an aspherical lens.

The asphere's more complex surface profile can reduce or eliminate sperical aberration and also reduce other optical aberrations such as astigmatism, compared to a simple lens. A single aspheric lens can often replace a much more complex multi-lens system.

-----Aspherical lenses can reduce aberration and distortion, depending on the material more real                                                                      -----Aspherical lenses are thinner, wearing a higher degree of beauty   -----Aspherical lenses are lighter, relieving the visual fatigue caused by oppression effectively
