Even a seemingly low power 5mW laser can do significant damage to unprotected eyes and can cause disorientation when it dazzles the viewer on the receiving end of the focused beam. At 1000 yards, the beam of a Green Laser Pointer expands to a diameter of about one foot while it’s intensity would equal looking at a 100 watt bulb at a distance of 10 feet. This intensity would effectively blind a person with dark adapted eyes for a significant period of time. This is why shining a Green Laser Pointer on an operating aircraft ( sometimes called “painting” ) on the ground or in the air can land the perpetrator in serious trouble with the federal authorities.
