The goal in laser eye surgery is to reshape the cornea, changing the focal point of the eye. Ideally the focal point is changed so it focuses perfectly on the retina. If you are nearsighted, the image comes into focus before it hits your retina If you are farsighted, the image doesn't come into focus before it hits your retina In a good eye the image is focused on the retina Lasers & Entertainment The Light and the dark side One of the most popular applications of laser technology, the Compact Disc Player, marked a revolution in digital video and sound technology. Lasers & Entertainment How a CD Works The CD Player works by using a laser beam to determine the lengths of a series of tiny ridges inside a compact disk. Inside a CD Player The music is digitally encoded in the ridge lengths which are measured by the reflected laser light
