Description


How does the human eye work?

The functional model of the human eye is an educational and exciting experiment set, with which you can explore with your students the anatomy and physiology of the most important sensory organ. This model allows you to understand different aspects of seeing, such as:

How is an object mapped on the retina?
How does the pupil adapt to different lighting conditions?
How does the focal length of the lens change to see close or distant objects sharply?
WAS are the most common visual defects and how to correct them?
WAS are the yellow spot and blind spot on the retina?

The functional model consists of an adjustable lens, a frosted glass panel as retina, a dummy panel as well as other experimental materials, with which you can show the function of the eye clearly. The set also contains various objects, which you can use as template for the illustration, as well as a rail, in order to vary the distance between object and lens. The model is robust and easy to use and is suitable for students in secondary school.

The illustrated manual contains information, tips and information about the test setup and the results.

With the functional model of the human eye, you can not only deepen your knowledge of the eye, but also train your observation and experimentation skills. The model is an ideal supplement to physics or biology lessons.
