About This Product
The model sets out the physics behind the eye: pushing or drawing the syringe thickens or thins the lens, so students see how focus is adjusted for near and distant objects. Lengthening or shortening the eyeball reproduces long or short sight on the retina, and placing a spectacle lens in front shows how the image is brought back into focus.
Frequently Asked Questions
How does the Functional Eye Model show accommodation?
The flexible lens is fluid filled and connected to a syringe; changing the pressure with the syringe changes the lens thickness.
Can it show long and short sight?
Yes. The length of the eyeball can be varied to simulate long or short sight, and lenses can be used to demonstrate correction with spectacles.
