Passed lecture in Geometrical and Instrumental Optics and Geometrical and Instrumental Optics Laboratory

Classroom

The subject of the lecture is the emmetropic and non-emmetropic eye as an image-forming optical system for different observation geometries, illumination and applied refractive error correction.

This lecture is an introduction to the Optometry I lecture and at the same time consolidates the knowledge acquired in the Geometrical and Instrumental Optics lecture. The aim of the lecture is to acquaint students (1) with selected models of the eye as an optical system forming an image under real conditions, i.e. taking into account illumination, spherical and cylindrical irregularities and changes in the structure and functioning of the eye progressing with age, and (2) with the basics of monocular correction, i.e. not taking into account effects connected with binocular vision. The formation of images in the eye is described in the language of geometrical optics. Only when discussing the resolving power of the eye are elementary concepts of light diffraction introduced.

Programme:

1. theoretical eye - models close to the real eye.

2. axes of the eye and angles between the axes

3. the reduced theoretical eye.

4. spherical irregularities (ametropies). Correction of spherical ametropies.

5. Accommodating the eye and its measures, presbyopia (presbyopia). Addition of nearsightedness

6 Astigmatism. Correction of astigmatism

7 Ocular magnification

8 Retinal image quality

9 Visual acuity measures and optotype tables

Lectures and exercises take place at a rate of 2h/week during the first eight weeks of classes of the summer term.

Students wishing to attend lectures should have passed the Geometrical and Instrumental Optics lecture (1100-1B05).

Regular attendance at exercises is a necessary and sufficient condition for admission to the examination. Students having more than TWO UNRELIABLE HOURS of absence from exercises will not be admitted to the examination.

During the semester, two colloquia consisting of a test part (multiple-choice test) and calculation tasks similar to those solved during the exercises or to homework tasks solved independently in preparation for the exercises in the Visual Optics Laboratory.

The final mark for the course Optics of Vision is the arithmetic mean of the two positive marks obtained at the colloquia, and if this does not satisfy the student, the student takes the exam and receives a final mark which is the weighted average of the marks from the colloquia and the exam. The weighted average of the marks from the colloquia is 1 and the weighted average of the marks from the examination is 3. The examination is a written test consisting, similarly to the colloquia, of a multiple-choice test and calculation tasks.

A student who has passed at most one colloquium is obliged to take the examination if he or she fulfils the conditions for admission to the examination (attendance at classes). The results of the 10-minute question papers conducted during the lecture do not influence the final grade.

Students who do not pass this subject should deregister from the list of those registered for the Optometric Laboratory I, taking place in semester III. Those who fail to do so will be deregistered by the Dean's Office.
