Product Summary
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, while the sealed tank holds water to simulate the vitreous humor. The size and orientation of the illuminated object is 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 changes in both the brightness and clarity of the image as the pupil size is reduced.
