Title: OPH105 Ophthalmic Optics II
Course Description:
The course will introduce the students to advanced ophthalmic principles of lenses and optical devices. The principles of transposition, nominal power, lens aberrations, prism and slab-off are presented. These principles are applied to an understanding of human refractive errors and the lenses required to correct them. Advanced components of the refractive power of the lens will be given, lens power calculations in different meridians, calculating vertical imbalance, calculating base direction of prisms, including base in, base out, base up, base down, and oblique prism. Lifestyle choices of single vision and multifocal glasses will be discussed.
Learning Outcomes:
As a result of taking this course the student will be able to:
Explain the vergence of light
Discuss human visual errors and lens choices for correction
Describe how to use a power cross
Transposition of plus and minus prescriptions
Calculate nominal power
Explain how to use a lens clock
Discuss lens power and position
Differentiate the types of chromatic aberration
Explain Prentice’s rule
Explain the effects of a centered lens in a decentered lens
Calculate total prism and base direction
Calculate vertical imbalance and slab-off
Demonstrate how to measure bifocal in multifocal lenses
