Lasers are important to help mankind in many different reasons. Some of these reasons include laser hair removal, some kinds of eye surgery, and lasers are said to help with the military in the near future. Laser hair removal is usually used for getting rid of unwanted hairs. And is just a easy alternative to regular waxing or doing it yourself. Some types of eye surgery require lasers to complete them successfully. This is usually very very precise as lasers get the job done at pin point accuracy. Besides medical uses the U.S. military have been testing laser weapons on battleships to attack or defend oncoming missiles. This will most likely replace small firing cannons or flares.
