CAS - Science Connections


Glare-Reducing Sunglasses, Inspired at Summer Camp.
We learned how to build a proper campfire, roast marshmallows, and tell ghost stories. We learned how to canoe, fish, and for the unfortunate few, treat a bad case of poison ivy. When our kids go to summer camp, should we expect more? In 1922, 13-year-old Edwin H. Land learned something so inspiring it changed his life forever:
"...While many will not recognize his name or the synthetic sheet polarizer he invented, most are familiar with the company founded by Land - the Polaroid Corporation - and the instant photography products he introduced in 1948. As the age of instant photography appears to be near its end,4 Land's summer camp-inspired invention of a synthetic sheet polarizer continues to live on, most notably as a popular glare-reducing feature in sunglass lenses.
