There seems to be no end to the stupid things that people can do. The latest incidents of U.S commercial aircraft being targeted by green and red lasers is a good example of how unintelligent some pranksters might be.
This is a particularly brainless prank because of the inherent danger involved. When a laser beam intersects with the eye, a condition known as laser induced flash blindness can occur. This holds true especially for people accustomed to low light levels, like a pilot.
The first image shown here is a look at a human eye that has suffered a hemorrhage due to laser-induced flash-blindness. To see what damage a laser beam can cause a CD case, check out the video above.
