Visual Optics Laboratory 1100-1BO29
The laboratory classes are designed to experimentally illustrate the formation of images on the retina of the emmetropic and ametropic eye. Students will be able to observe reduced quality of the "retinal" images resulting from the refractive errors, and observe how the quality of images improves with the application of properly selected correction. Some exercises will include a calculation part, such as calculating the range of accommodation for an eye with an implanted pseudo-accommodating lens or calculating the power of eyeglasses for correction of a lensless eye.
Programme:
1. Construction and study of the model of the emmetropic eye, determination of the range and calculation of the amplitude of accommodation.
2. Construction of the model of the myopic eye and determination of correction to the distance.
3. Construction of the model of the hyperopic eye and determination of correction to the distance.
4. Determination of reading correction for hyperopic and myopic presbyopes.
5. Observation of retinal astigmatic images and determination of spherocylindrical lens power.
6. Construction of a model of an eye with simple astigmatism and determination of the correction to the distance using a stenopic slit.
7. Determination of the magnification of the retinal image and study of the effect of pupil size on the quality of the retinal image with different types of ametropia.
8. Correction of spherocylindrical refractive error using stenopic slit and Jackson crossed cylinder.

Learning outcomes
The student knows and understands refractive errors (myopia, hyperopia, presbyopia and astigmatism) and their impact on retinal image quality.
The student is able to build models of the eye burdened by various refractive errors on an optical bench. He knows how to determine the far point of the eye and is able to correct the refractive error on this basis to achieve the highest quality retinal image.
Assessment criteria
In order to pass the laboratory, it is necessary to obtain a positive grade from at least seven exercises and to pass a practical test. At the practical test, the student performs a drawn element of one of the eight exercises. The final grade is the arithmetic mean of the eight grades, i.e. the grades for the seven highest-scoring exercises and the grade for the final test.
Students who fail this course will be deregistered by the Dean from the list of those registered for the Optometric Laboratory I, held in the third semester.
