Learning objectives
The course aims to enable the student to know and understand through theoretical lectures and practical optics problem solving the basics of lens correction of refractive defects.
The student must also know the mechanisms of light signal generation and transmission. The structures and defects that affect proper binocular and colour vision.
Prerequisites
Examination of "ocular motility, binocular vision and pathophysiological bases of optics"
Course unit content
The course aims to deepen the principles of ocular refraction on the following topics:
- effect of lenses on light radiation
- effect of the ocular diopter on light projections and optical aberrations in the visual system
- biophysical and chemical mechanisms for photoreceptor activation
- signal transmission along optical pathways and colour vision
- physiology of the visual cortex
Full programme
Principles of refraction and measurement of visual acuity;
Principles of correcting refractive defects with spectacles and contact lenses;
Principles of correcting refractive defects with lenses;
Principles of light stimulus creation and interaction between retinal neurons;
Stimulus transmission pathways from the optic nerve to the visual cortex;
Types of optic pathway neurons, trichromatic teria and organisation of visual modules.

Teaching methods
The course will be conducted through lectures, the iconographic support of which will be provided to the students at the end. These practical topics will be addressed during the lectures.
Assessment methods and criteria
Preferably written examination by means of open-ended answers and optics calculations.
