BA Early Childhood Studies Level III
Core Module -
Semester 3 - 15pts

Introduction

This module will introduce you to ophthalmic lens theory. You will gain a knowledge and understanding of basic optics, spherical, astigmatic and toric lenses, the lens measure, lens thickness and the effect of incorporating an ophthalmic prism in a spectacle lens. You will also learn how the field of view is altered when looking through a spectacle lens.

At the end of this module, you should be able to:

• Describe the materials and recall the terminology used in ophthalmic lenses
  

• Demonstrate a knowledge and understanding of basic optical principles which apply to ophthalmic lenses, the lens measure and its relation to lens thickness
  

• Recognise and define terms relating to ophthalmic prisms
  

• Apply basic mathematical concepts to solve ophthalmic lens problems both graphically and by calculation
  

• Carry out all types of transposition
  

Assessment 

• The module will be examined at the end of semester 2 in a 1.5 hour closed book examination which will consist of structured questions.
  

To pass this module you will need a mark of 40%
