- Synopsis:
-
The student is introduced to the basic operation of the Optical Laboratory. The student learns the habits that are standard in completing spectacle correction. The student learns to obtain individual client parameters, centration and selection of the appropriate lens for subsequent eyeglass fitting. The student also learns to adjust and repair spectacle correction.
- Requirements:
-
Credit requirements:
1. Absences (up to 20%, i.e. 3 absences per semester) must be made up with another parallel class discussing the same topic, an examination, or possibly the defense of a seminar paper. Sickness documented by sick leave or a doctor's report is considered an absence and must be made up.
2. Continuous completion of the assignments given in class. E.g. lens grinding, spectacle repair, measurement of individual client parameters, etc.
Exam requirements:
1. The student will take an oral exam at the end of the class to demonstrate mastery of the material covered. The oral exam will consist of three questions randomly selected from topics covered in lectures. The student will have 10 minutes to prepare.

- Study Objective:
-
The aim of study is to obtain a Spectacle of technology as knowledge of general mechanical characteristics of materials and their processing methods, both at the level of factory production of individual parts of the semi-glasses, and their modifications into the final shape of glasses with which students learn the practical training course.
