Course Description

This course will follow light as it passes through the different anatomical structures of the eye. The course is designed to create a comprehensive knowledge base of how anatomical structure interacts with light to produce visual perception, refractive error, and the correction of refractive error with contact lenses. The course is written for the layperson but would also serve as a source to build base knowledge to support and enhance understanding of optical principles related to the eye, refractive error, and contact lens use for optical apprentices, opticians, or anyone studying for ABO/NCLE certification.

Course Objectives

  • Understanding how the eye is a focusing structure, and how imperfections in the visual system are corrected with contact lenses
  • Cover the prescription components of sphere, cylinder, and axis and describe what they are based on
  • Explain how light gets converted to an image

Course Assessment

There is a 40-question test at the end of the course. A successful passing score of 80% is required on all ABO-NLCE continuing education courses in order to earn the designated number of credits. You will know your grade instantly after completing the course.
