Human Vision

The human vision interactive Java tutorial explores what happens in the human eye when an image is focused on the retina.

To operate the tutorial, hold your mouse cursor over the butterfly, click on the left button and drag the butterfly back and forth in front of the eye. The image of the butterfly will increase or decrease in size depending upon how far the butterfly is from the eye.
