Simulators designed to simulate real organs or activities can be valuable tools in the process of medical training. The main purpose of screen-based computer simulators is to train and assess knowledge and decision-making in medical practice. The presented application is in the form of an educational game, which is a subcategory of serious games. The game is supposed to help learn the anatomy of a normal and a pathological human eye. It is dedicated mainly to high school students in biology classes and medical professionals. The interaction mode is a single player. Users have three main ways of learning the eye anatomy: the Anatomical Model, the Quiz, and the Disorder Catalogue. The Anatomical Model presents the elements of the normal anatomy of the visual system as well as its detailed description. In the “Quiz” mode, users can check their own knowledge of the eye anatomy in the question and answer mode. The “Disorder Catalogue” contains a description of the selected eye defects and models displaying vision before and after correction.
