Focus on Eyes

The human eye is immensely complex, able to adjust rapidly to changing light conditions. On a large scale it can pivot, focusing on specific points, and identify brightness in contrast to darkness. On a smaller scale it can control the total light entering the eye by changing the size of the iris. This model eye is designed to be a teaching tool - fully mechatronic, a final version of this eye will respond to varying light intensities shining from different angles. This eye model illustrates the complex movements of the human eye for students.
