Overview 

Near Vision lenses are designed for intermediate and near vision (not distance and near as with traditional multifocals).  When a lens style is identified as a Near Vision style in Rx-Universe, that implies several things:

  • The add power is converted to a degression based on rules specific to that lens style.
  • The lens blank with the specified degression is selected.
  • Power is measured at the NEAR reference point, not the distance. 
  • Prism, however, is measured at the PRP (in the distance or intermediate section of the lens).
  • True curve of the near vision blanks is at the NEAR reference point (not distance as with a regular progressive).
  • Wrap compensation CANNOT be done on a near-vision lens.
