Course Description

Covers fundamentals of contact lens. Includes principles of lens structures, materials used in manufacture, categorization, comparison of characteristics of soft and rigid lenses. Includes theory and utilization of instruments commonly used in fitting and assessing contact lenses. Includes use of keratometer, biomicroscope, radiuscope, lensometer, gauges, loupes, magnifiers and fluorescent tubes. Audit available.

Intended Outcomes for the course

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

  • Explain the methods of fitting contact lenses
  • Explain differences in contact lenses and their appropriate usage.
  • Use contact lens assessment and fitting equipment, including  keratometers, biomicroscope, radiuscopes, lensometers, gauges, loupes, magnifiers and fluorescent tubes, in order to fit and assess contact lenses.

Course Activities and Design

This course will be presented by means of lecture/discussion, audio/visual presentations, handouts and in lab demonstrations. Guest speakers and field trips may be used to enhance mastery of course goals and student learning.

Outcome Assessment Strategies

At the beginning of the course the instructor will detail the methods used to evaluate student progress and criteria for assigning a course grade. These may include examinations, quizzes, homework assignments, research papers, and student participation during class sessions.
