See you around

By Debra Dobbins

Peripheral vision is the vision that we have on the sides of our heads. If someone says, “I saw you out of the corner of my eye,” that person has used peripheral vision.

“Peri” is a Greek word part that means around. It is included in words such as perimeter (“meter” means measure) and periscope (“scope” means look).

The illustration below shows two simple periscopes. To learn how to make one out of milk cartons and pocket mirrors, go to http://www.exploratorium.edu/science_explorer/periscope.html.

BTW, grandparents, parents and teachers all have excellent peripheral vision. It comes with the job.

Principle of the periscope. The periscope on the left uses mirrors at location "a" whereas the right uses prisms at "b". The observer is "c".
