With this model the functions of the human eye can be taught very effectively. By moving the retina, the shape of the eye can be changed. The lens and ciliary body are made of silicone to allow the change of form and thickness of the lens. Pictures can be projected on the retina that allows you to demonstrate:

• Accommodation of the lens
• Near point of vision
• Myopia (near sightedness)
• Hypermetropia
• Presbyopia
• How to correct these problems with glasses

Comes with detailed instruction manual.
