inverting spectacles

The Inverting Spectacles comprise spectacles with two fully rotatable inverting prisms in a shielded spectacle frame. The inverting prisms produce a lateral inversion of the rays – causing the world to turn "upside down". Besides being an effective demonstration of the functioning of an inverting prism, experiments involving inverting spectacles encourage a better understanding of the visual process and the functioning of the brain. 

uses of the inverting spectacles

With the Inverting Spectacles, even the apparently simplest things in life (holding and picking up objects, drawing, orientating oneself in a room) become unexpectedly difficult. This allows for an entertaining way to learn about inverted prisms.

The spectacles are suitable for various experiments such as:

• Demonstration of the path of rays through an inverting prism
• Drawing and writing
• Seeing, picking up and balancing objects
• Throwing and catching a ball
• Pouring water
