Description
ABO 1 Credit (Techincal Level 2) Florida 0 Credit This course will explain lens power, nominal power and focal length of lenses. In addition, sagittal depth and thick lens design will be presented. Understanding these basic concepts helps the ECP to understand the final form of the patient’s lens. LEARNING OBJECTIVES: At the completion of this subsection, the student should be able to:
- Calculate nominal power
- Explain base curve and tool curves
- Calculate both focal length and dioptric power
- Be able to explain the relationship between focal length and lens power
- Discuss sagittal depth of a lens surface and how to calculate thickness of a lens
- Calculate the power of a thick lens
