Do aspheric lenses benefit farsighted or nearsighted prescriptions more?
  1. Farsighted
  2. Nearsighted
Explanation
Answer: A - Aspheric lenses benefit a farsighted person and prescription more.

Since a plus power is used to correct a farsighted person, the lens will be thickest in the middle. An aspheric lens reduces the thickness by eliminating some of the curve. Aspheric lenses reduce the magnification of the lens that the person sees when looking at someone wearing a high plus power.

It also creates better vision for the wearer and is more comfortable since the weight is also reduced.
