Which of the following statements accurately describes aspheric lenses?

Aspheric lenses are designed with a curved profile that changes gradually from the center to the edges, rather than maintaining a constant spherical shape. This design allows them to reduce distortion and improve image quality compared to traditional spherical lenses. A flatter profile not only enhances aesthetics by creating a thinner lens but also helps to correct vision more effectively, particularly for higher prescriptions. Aspheric lenses minimize peripheral distortion, enabling clearer vision across the entire lens surface, which is especially beneficial for individuals with certain vision impairments.

The other statements do not accurately apply to aspheric lenses. They are not purely spherical; they diverge from that shape to provide specific optical benefits. While some lenses may offer greater magnification, it is not a defining characteristic of aspheric lenses. Furthermore, while aspheric lenses can be prescribed to correct various vision issues, including astigmatism, they are not limited to this correction and can address a range of refractive errors.
