Course objectives
At the end of this course a student will be able to understand optical function of the eye, to describe their refractive errors and to suggest appropriate correction lens.
Syllabus
  • Accomodation. Measurement of accomodation, Duane graph, optical diagram of the accomodation process - examples.
  • Analysis of the accomodation process. Correction of myopia and hypermetropia for distance vision - examples.
  • Analysis of the accomodation process. Correction of myopia and hypermetropia for near vision - examples.
  • Spectacle lenses. Bi, plan, periscopic lenses, menisci - examples.
  • Spherical best-form spectacle lenses. The Petzval surface, The Petzval-Coddington condition, tangential and sagittal bundle of rays.
  • Astigmatism of a thin lens. The Tscherning ellipse, the main points of the method of the calculation of spherical best-form lenses.
  • Realization possibilities of spherical best-form spectacle lenses.
  • Aspheric spectacle lenses. Correction of aberration by an aspheric surface.
  • Bifocal spectacle lenses. Conditions for the image-jump removal on the interface of the lens portions.
  • Cut bifocal spectacle lenses. Calculation of the basic parameters, prismatic effect.
  • Trifocal spectacle lenses. The main working point, accomodation intervals.
  • Sealed bifocal spectacle lenses. The proposal of the calculation of the radii of curvature, check of apical refraction by a tabelar calculation of paraxial ray.
  • Multifocal spectacle lenses. Design, width of the central band, hard and soft type of the lens. Lenticular spectacle lenses. Prismatic glasses.
  • Eye astigmatism. Etiology of astigmatism, classification of astigmatism, correction of eye astigmatism.
  • Cylindrical and toric spectacle lenses. Rules for the recalculation of astigmatic combinations - examples.
  • Exercises are immediately linked to the lectures.
