Subjective Refraction II.
- Grading of the course requires grading of the following courses:
- Clinical Refraction (17PBONR)
Subjective Refraction I. (17PBOSUR1)
- Department of Natural Sciences
During the lectures, students deepen their theoretical knowledge and practical skills of subjective refraction with the test frames and test sets of glasses. Further tests will follow on binocular balance, practice working with phoropter and other techniques.
80% attendance at lectures, practical exam, completed refractive cards, written and oral examination

- Study Objective:
Course subjective refraction II. is designed to give a comprehensive view of subjective refraction examinations and practical mastery. The goal is to providing theoretical assumptions and practical training of subjective refraction measurement with an emphasis on binocular accommodative tests and mastering techniques for near and intermediate distance.
