FSI-TF0Acad. year: 2017/2018
The optional course PHYSIOLOGICAL OPTICS takes the form of lectures and completes and extends education of physical engineers in the field of optics giving greater details in composition and function of the human eye. It provides students with information about the physiological construction of the human eye described as an optical transformation system. Also dealt with is the accommodation of the eye, sensibility of the eye, the limit of resolution of the human eye, as well as methods for its measuring. The optical aberrations of the eye are described and the processes for their compensation are proposed.
Learning outcomes of the course unit
Students of the course PHYSIOLOGICAL OPTICS will acquire the fundamental knowledge in the science of eyesight. They will be made familiar with the human eye ametropia and prepared to propose total optometrical correction.

Planned learning activities and teaching methods
The course is taught through lectures explaining the basic principles and theory of the discipline.
Assesment methods and criteria linked to learning outcomes
Course-unit credit is awarded on condition of having attended the final discussion.
Language of instruction
The aim of the course PHYSIOLOGICAL OPTICS is to familiarise students with the optical construction of the human eye. They will learn about possible refraction aberrations (myopia, hypermetropia, presbyopia, astigmatism, anisometropia, aphakia) and ways of correction of those aberrations with optical aids.
Specification of controlled education, way of implementation and compensation for absences
Attendance at lectures is not obligatory.
Type of course unit
13 hours, optionally
