## Course Overview

This course is intended for beginning, intermediate, and advanced levels.

After completing this section the student should be able to do the following:

• Identify light rays with the shortest and longest wavelengths
• List the colors in the visible light spectrum from shortest to longest wavelength
• Identify the wavelength of red light
• Identify the wavelength of violet light
• Describe the Quantum theory
• State the speed of light in a vacuum
• Describe the wave theory including the 2 factors that affect how light rays will be bent
• Define Index of refraction
• Define reflection and how the angle of reflection relates to the angle of incidence
• Identify light rays that are in phase and light rays that are not in phase
• Describe how light reacts when they pass through a prism
• Identify converging and diverging lenses as plus and/or minus lenses
• Find the focal point of a lens with a known power
• Identify where the focal points of plus powered versus minus powered lenses fall
• Find the displacement of an image given the power of a prism
• Find the sphere cylinder equivalent of a given prescription
• Transpose a prescription from minus to plus cylinder and vice versa
• Identify types of lens aberrations
• Describe minification and magnification aberrations and why they occur
• Use Prenticeï¿½s rule to find induced prism
• Describe the base curve of a lens and what is used to measure it
• Identify the refractive power of the lens and cornea
• Describe the physiology of an emmetropic, myopic, hyperopic, and astigmatic eye
• Calculate the far point of an eye given the refractive error
• Define with the rule, against the rule, and oblique astigmatism
• Understand the types of astigmatism- simple myopic, compound myopic, simple hyperopic, compound hyperopic, mixed
• Calculate
total prism effect OU when given prism amounts for OD and OS-
understand how prism in each eye affects total prism amounts

Here is what some ophthalmic personnel who took this course had to say:

“this was a great indepth course in optics.” M.M., COT

“Wonderful explanations of a difficult subject- very useful for preparing for certification exams!” L.C., COMT

This course should take approximately one hour to complete.
