6J10.10 - Model of an Eye

Code Number:
6J10.10
Demo Title:
Model of an Eye
Condition:
Good
Principle:
Geometries of the Eye
Area of Study:
Optics
Equipment:
Eye Model.
Procedure:

See also 6J10.10 in Physics of the Human Body.

No preparation except for routine cleaning.

The Eye charts can be used to show normal vs. abnormal eye function.

The Pasco eye model has an adjustable focal length lens that is quite good for simulating near sightedness, normal focusing, and far sightedness. A camera may be placed so that it projects the images from the "retina" viewing screen to the entire class.
