OD 240 - Ophthalmic Dispensing III

Credit Hours: 3

Instruction will include, but not to be limited to the following: Review of OD150, preparation for American Board of Opticianry National Certification Examination, study of presbyopia and accommodation and convergence; segment size an add power determination, 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 Rx 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.
