Credit Hours: 3

Introduction to prism in the ophthalmic lens including decentration, deviation, types and uses. Single vision and multifocal prescription analysis including the application of bifocals, trifocals, progressive and vocational lenses. The availability and use of conventional and specialty ophthalmic frames.

Course Outcomes
Upon completion of this course, the student will be able to:

  • determine uses of specialty frame products including sport/safety and other specialty frame designs;
  • define boxing system terminology and frame and lens measurements including application;
  • calculate lens decentration and minimum blank size as it correlates to the boxing system;
  • apply formulas used in spherical and cylinder lenses;
  • perform prescription transposition, optical cross, nominal power and lens curvature formulas;
  • perform an analysis of ophthalmic prisms which will include descriptions of prisms, classification of prismatic effects and measurements, splitting, and combining of ophthalmic prisms;
  • the proper use of Prentice's Rule in decentering single vision lenses to create prism; and
  • identify the proper functions of multifocal lenses including lens decentration/inset and proper segment placement.
