4} Eyes = This is designed as a regular unit with 4 back lit graphic panels and 1 3D model. Three of the four graphic panels are animated:

(#1) panel depicts the main parts of the eye and how light progresses into it using LED’s for animation.

(#2) panel is a shadow box of a simplified working model of the cones and rods of the eye. In this section the visitors will expose the working models of cones and rods to different colored lights and see how they react. The relative level of reaction appears on a graph.

(#3) panel pertains to eye health and defects, explaining the basics on eye care and common defects.

(#4) panel is a monitor screen that displays the images that a miniature camera in the 3D model of the eye sees when it is in it’s closed position.

Two large models of the eye grace the main council area. One is open and the interior lights up for easy viewing. The whole eye model is closed and works like a camera allowing the visitors to aim it towards each other and see an image on a screen in the (#4) panel area.

Also included is a list of True or False Questions. Next to this list is a set of push buttons allowing the visitor to select the appropriate answer. The DAST technology portion of the exhibit allows the user to hear positive feedback or be prompted to try again.
