Optometric Examination A will introduce you to basic eye tests - which are known as refractive examinations. You will learn about the basic optics of the eye and errors in the focusing of light by the eye which affect visual acuity: myopia (short-sightedness), hyperopia (long-sightedness) and astigmatism. You will be able to perform a basic refractive examination, communicate adequately with patients to gain their co-operation during the examination and demonstrate manual dexterity in the use of refractive instrumentation.


To introduce students to the basic methodology of refractive examination.
