Paper Abstract

Nowadays, new technologies have great influence on our lives and how we access to the information. The new generations have never known a world without them and make use of these new technologies in practically all facets of their day-to-day. Education systems have also evolved rapidly and frequently make use of learning strategies based on interactive tools. In this work we have created a graphical user interface with GUIDE, a development environment of MATLAB, to show, in a simple way, how the eye works. This interactive program is addressed to the first courses of secondary education and designed to introduce them to the basic concepts of the normal refractive condition of the eye and the most common refractive errors, as myopia and hyperopia. The graphic interface makes use of the simplified model of the eye, where the optic system of the visual organ is represented by a converging lens (cornea and crystalline) and a screen (retina). Emmetropic, myopic and hyperopic eye operation is shown graphically to the students, as well as how these focusing errors can be solved with a diverging and converging lens, respectively. This teaching tool was used this academic course in the Colegio Hogar de Santa Margarita (A Coruña) for a better understanding of the students in this matter and to catch their attention to the world of Optics and its importance.
