  • A brief introduction to geometrical optics. Refraction at a spherical surface, reduced distances, vergences, definition of optical power; Gauss projection equation and the equations of vergence for one spherical surface and the lens; multistage optical system and draw their main parameters, basics of optical aberration systems. Creation of visual perception. The eye and its optical system. The construction of the eye and its optical system, its model and their use. Aberrations of the optical system of the eye, an overview of refractive errors. Emetropia and ametropia. The causes, classification and spectacle correction of spherical ametropia. Astigmatism, the causes, classification and correction. Anisometropia, aniseikonia. Accommodation and its description. Theory of accommodation. Accommodative stimuli. Empty field myopia. Night and instrumentation myopia. Interval and amplitude of accommodation. Changes in accommodation with age, presbyopia, presbyopic addition for near. Aphakia. Amblyopia. The influence of the pupil on the optical imaging of the eye. Diffraction-limited eye. Scattering ring. Depth of field. Stiles-Crawford effect. Pupillary reflexes. Visual acuity and its measurement.
