What Experiments can be used to determine you peripheral vision?

Question

Need for an assingment any suggestions would be much appreciated

Answer 1

They have a gizmo for testing this at my eye doctor's office.  It's fairly complicated,but you could make something much more simple.

Take a board, maybe two feet long.  Put a notch in the middle on one edge.  In the center of the board are two 'arms' on pivots that can swing out towards the ends of the board.  On the ends of the pivots are two circles of red paper (or some other bright color).

Now you put your nose in the notch so the board is level with your eyes, and your nose is centered on the board..  You stare straight ahead.  The arms are centered, perpendicular to the board, so you are looking right at the red circles.  You move the arms slowly to the sides until you can no longer see the red circles.  Then you look at the angles of the arms to the board.  You could mark the board with markers to show the angle, or just glue a protractor to it to show the angles.

Now you can see how much to each side your peripheral vision goes.

If this isn't clear, write me and I will draw a diagram and send it to you. I can't do that here, or in a Yahoo message.  But I think you get the idea.
