Aspheric lenses are favored for cataract patients primarily because they provide better optics. These lenses have a varying curvature that helps to minimize optical aberrations, resulting in improved image quality. This design allows for a more natural focus across different viewing distances, which is particularly beneficial for individuals recovering from cataract surgery.

Cataract surgery often involves replacing the clouded natural lens of the eye with an artificial lens. By using aspheric lenses, patients may experience enhanced contrast sensitivity and reduced distortion compared to traditional spheric lenses. This is especially important in low-light conditions or when looking at objects at varying distances, significantly improving the overall visual experience after surgery.

Considering other aspects like weight, cost, and maintenance, while they might be relevant in specific contexts, they do not directly impact the primary advantage that aspheric lenses offer in terms of visual quality for cataract patients.
