Course Description
Addendum to Course Description
Covers fundamentals of contact lens. 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 fluorescein dye and cobalt blue filter.
Intended Outcomes for the course
Upon successful completion of the course students should be able to:
-
Explain the methods of fitting contact lenses.
-
Explain differences in contact lenses and their appropriate usage.
-
Demonstrate the use of contact fitting equipment, including keratometers, biomicroscope, radiuscopes, lensometers, gauges, loupes, magnifiers, fluorescein dye and a cobalt blue filter.
Course Activities and Design
This course will be presented by means of online 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.
