On meeting the American Optical Company (largest sunglasses manufacturer):
The three men walked into a room filled with blinding sunlight. As they squinted against the intensity of light from the windows, Land said in a pleasant voice, "I apologize for the glare. I imagine you can't even see the fish." His visitors, handing their briefcases and coats to George Wheelwright, stared at Land blankly.
"Here, look through this." Land gave each a square of polarizer. As they faced the windows the glare vanished. There was the bowl on the windowsill, the goldfish swimming serenely in their warm environment as if suspended in air. "How many fish do you see?" asked Land in the voice of a kindly professor addressing his young pupils on their first day.
"Six," said the three dutifully.
"This is what your new sunglasses will be made of," said Land. "Its called Polaroid."
