VC 240 - Ophthalmic Dispensing III


Credit Hours: 3

Instruction includes preparation for American Board of Opticianry National Certification Examination. This course includes the study of presbyopia, accommodation, convergence, segment size and add power determination. Additional topics include vertical imbalance and methods of its correction, progressive lenses, technological advancements, fitting and problem solving, absorptive lenses and the use of specialty lens coatings.

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

  • determine the effects of presbyopia and select appropriate lens for its correction;
  • evaluate difference lens styles;
  • compare and contrast the multitude of lens styles available;
  • manipulate patients prescription to meet differing visual requirements;
  • distinguish proper segment placement of varying multifocal styles;
  • identify anisometropic prescriptions leading to vertical imbalance;
  • determine proper method for the correction of vertical imbalance;
  • conduct use of proper formulas for calculating vertical imbalance;
  • identify the concept and early design of progressive addition lenses;
  • analyze the current technology used in the creation of modern progressive lenses;
  • identify the proper methods used in the fitting and dispensing of progressive lenses;
  • determine design characteristics and proper uses of specialty progressive lenses;
  • evaluate effect of digital surfacing principles with evolving progressive lens design;
  • distinguish between the different forms of glare and proper lens selection for their management;
  • identify differing forms of radiant energy and its effect on the eye;
  • identify differing absorptive lenses and their appropriate uses; and
  • evaluate the effects of different lens coatings on ophthalmic lens surfaces including scratch resistant, anti-reflective and mirror.
