Learning outcomes
|
Acquiring practical skills related to the production of spectacle correction aids. The graduate of the subject will be able to independently make a spectacle correction device based on the correct selection and entry of individual parameters, and will also carry out its anatomical adjustment, reparing and measurement.
By completing the practical teaching of eyeglass technology, the student is qualified to independently perform the activities of the subject content. He is responsible for his actions. Students gain practical skills in making eyeglasses, using modern equipment to produce them. They will learn communication skills in counseling for different situations spectacle correction, orientation in the range of corrective lenses and optical frames.
