Ottica_fisiopatologica
A.Y. 2023/2024
Learning objectives
The course aims to provide the concepts necessary to understand the functioning of the eye as an optical system and to know the ocular refractive defects and how to quantify and correct them.
Expected learning outcomes
At the end of the course the student will have to know and will be able to apply the principles of optics and their application to human vision, it will be able to identify defects of ocular refraction, know how to quantify them and know how to correct them using objective and subjective methods correctly.
