Objective of course of lectures: Teach students how to handle, apply and take out contact lenses, to carry our previous measurements necessary for fitting of contaxct lenses, how to work with rent lamps, refraction through contact lense in the eye.

Content of course of lectures:

1. History of contact lenses. Division of contact lenses. 2. Materials used in contact lenses and requirements. 3. Technology of contact lenses production. Standards. 4. Examination of contact lenses parameters. Measuring raduis, dioptric strength, diameter, thickness. 5. Adaptation of contact lenses. 6. Adjustment equipment. Rooms, instruments, hygienic requirements. 7. Adjustment procedure. Short revision of eye anatomy and physiology. Adjustment requirements. Adjustment rules. The relation between cornea and contact lense curvature. Eye examination by means of biomicroscope.  8. Anatomic and physiological characteristics of eye and their influence on the selection of lenses. Cornea. Eyelids. Pupils. Tear film. Conjuctiva.  9. Psychological approach to lense fitting. 10. Steps in lense fitting. Selection of lenses. Optical calculation. Identificaltion of lense parameter.

General and specific competences (knowledge and skills): With the exam passed, students will be able to assess justifiability of contact lense application in eyesight correction, to determine the type of contact lenses; they will know how to fit lenses, explain the risks of waring and handling lenses, to give instructions on their proper and safe maintenance, as well as on the need for regular checks of eyes and contact lenses.
