A little eye experiment
« on: 11/05/2011 23:39:59 »
I guess I must have ben bored when I stumbled across this:

If you close your left eye, and put your finger about an inch or two in front of your right eye. Focus on an object futher away(like your computer screen) and slowly move your finger from left to right, in front of your eye.

You will notice the object/image you are focusing on will appear to bend when it gets close to the right hand edge of your finger.

If you do the same thing with your left eye, the bending will be on the left hand edge.

Does anyone know what causes this?

Ok that makes sense. But why does it seem to diffract more on the right side of the object, than the left?
