1. The difference between Aspheric and Spherical Lens
Conventional spherical lenses are lenses that have the same curvature across the entire front surface.  These designs have some distortion when you look away from the center of the lens in any direction.  Strong prescriptions for hypermedia or “farsightedness” produced in spherical lenses result in unwanted magnification causing objects to appear larger and closer than they actually are.  Consequently, the wearer’s eyes also look larger.  Strong prescriptions for myopia or “nearsightedness” do just the opposite.  They make objects look smaller and further away while making the wearer’s eyes look smaller. 
  1. The Advantages Of Aspheric Lens
Aspheric lenses are designed to have a flatter curved surface. When compared to spherical lenses, these lenses are much thinner, lighter and flatter. This makes for more comfortable wear and a more cosmetically pleasing appearance. For plus lenses, there is less bulging of the lens from the frame, giving the glasses a more flattering profile. The effect is less dramatic in minus lenses, but aspheric lenses still provide a noticeable reduction in the thickness of the lens edges. In plus lenses, the aspheric lens helps make the wearer look more natural by reducing the “bug-eye” effect that spherical plus lenses have.
In summary as following,
  • Less bulging of the lens, giving you a sleeker profile
  • More frame options for individuals with strong prescriptions
  • More natural appearance of the eye (reduces the eye magnification that occurs with farsightedness and the smaller appearance of the eye that occurs with nearsightedness)
  • Lightweight (less material is used to make the lens)
  • Better peripheral vision
  • Higher image quality (more consistent magnification throughout the lens)
