1.What is an Aspheric Lens?

Traditional lenses have a bulgy, curved shape. Imagine the spherical surface of a ball. An aspheric lens is designed with less curvature than its traditional counterpart. Think: flatter and thinner. In both farsighted and nearsighted prescriptions, aspheric lenses provide a slimmer profile and minimize eye distortion without compromising optical quality.

2.Benefits of Aspheric Lenses
 
  • Less bulging of the lens, giving you a sleeker profile
  • More frame options for individuals with strong eyeglass prescriptions or reading powers
  • A 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)

3.What is UV 400?

Simply put, UV 400 means that the lenses will block Ultraviolet (UV) waves shorter than or equal to 400 nano-meters (nm). All UV waves come in different lengths as shown in the chart below.
