Re: Pulfrich Effect

The Pulfrich Effect is used by eye doctors to test if one eye receives more light than the other - for example one eye may have a cataract. They would do the test using a pendulum. The the path of the pendulum would be seen as an elliptical one.

Here is a clip which shows the Pulfrich Effect very well.

remember to cover one eye with darkened glass.
