We learning about light refraction in class the other day and I was just wondering what man made objects used it for and what man made light refraction is used for.

All kind of optic devices. A simple lens, for example.

A man on The Science Channel said something interesting. Noting that the ability of a lens to focus relies on the light changing speed when it crosses the boundary between two substances, and noting that the eye needs a lens, the man on TV pointed out -- and this is a close paraphrase: "If light traveled at the same speed in all materials, everyone would be blind."

prism , binocluors , beam splitter , gravitational lensing ( bending light around the sun for example) , camera , magnyfing glass , x-ray prisms , cerenkov radiation in a nuclear reactor . x-ray rainbows

Just wanted to thank everyone who's replied so far, I really didn't know it was used to do so much!

I wonder if somewhere in evolutioniary history some organisms have had eyes which work on the same principle as the pinhole camera.There is no refraction needed with these.
