Description

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.


Features

  • Working Model of the Human Eye: Two lenses are used to form images on the retina. Sealed tank holds water to simulate the vitreous humor. Size and orientation of the illuminated object can be easily measured.
  • 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.
  • 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.
  • Movable Retina: Three positions 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.
