Explore the Optics of the Human Eye

An affordable 3-D working model

The Teaching Challenge

One of the most elegant and intricate optical devices on Earth, the human eye offers a wealth of valuable information about the study of light and lenses.  Yet, outside of messy (and limited) dissections of cow or sheep eyes, it has proved an elusive concept . . . until now

The PASCO Solution

The PASCO Human Eye Model provides an affordable and complete solution to studying the optics of this complex organ.

A dramatic demonstration of how the eye works, the Human Eye Model allows students to see all of the various parts of the eye including the pupil, corneal lens, vitreous humor, crystalline lens, and retina and how each contributes to our ability to see. 

Better yet, almost all of these can be adjusted to simulate focusing on near or far objects, defects in vision as well as how eyeglasses can correct them, the difference between a human pupil and that of a cat and more!

Study Defects in vision

  • Normal vision
  • Nearsightedness
  • Farsightedness
  • Astigmatism

Use the included plastic lenses to create images for normal vision, farsightedness, nearsightedness and astigmatism. Additional lenses are placed in front of the eye to correct for vision problems.

Study the Optics of Normal Vision and Vision Correction:

 Use the included plastic lenses to create images for normal vision, far-sightedness, near-sightedness and astigmatism. Additional lenses are placed in front of the eye to correct for vision problems.

Many other options

Fixed Corneal Lens and Interchangeable Crystalline Lens: The crystalline lens is surrounded by water (vitreous humor). By changing the crystalline lens, the eye can focus on both near and far objects.

Moveable Retina: 3 positions to demonstrate near-sightedness, far-sightedness and normal vision.

Variable Pupil Size: Students can observe the change in brightness and clarity of the image as the pupil size is reduced.
