Third-order formulae calculate spectacle lens distortion from conicoid aspheric surfaces. While some distortions and off-axis power errors can be corrected, the required lens curvatures are not cosmetically viable.

Area of Science:

  • Optics
  • Ophthalmology
  • Lens design

Background:

  • Spectacle lenses often incorporate aspheric surfaces to correct aberrations.
  • Understanding distortion in lenses with conicoid aspheric surfaces is crucial for visual quality.

Purpose of the Study:

  • To develop third-order formulae for calculating distortion in spectacle lenses with conicoid aspheric surfaces.
  • To investigate solutions for correcting rotatory or peripheral distortion.

Main Methods:

  • Development of third-order mathematical formulae.
  • Analysis of lens designs featuring one conicoid aspheric surface.

Main Results:

  • Formulae for calculating distortion in thin spectacle lenses with conicoid aspheric surfaces were derived.

  • Simultaneous correction of oblique astigmatism and one type of distortion is possible.
  • The necessary lens curvatures for simultaneous correction are cosmetically infeasible.

    • Conclusions:

    • Third-order analysis provides a method for understanding distortion in complex spectacle lenses.
    • While optical correction is theoretically possible, practical cosmetic limitations exist for lenses with conicoid aspheric surfaces.
