How powerful is the laser pointer?
The power of a laser pointer depended on its power. In general, low-power laser pointers (0.4 to 1 millivolts) generally do not cause harm to the human eye and skin if the exposure time is not long. However, the more powerful laser pointer (3-5 millivolts or more) can cause damage to the human body and can even ignite matches, firecrackers, and paper. Some laser pointers had a power of up to 100 to 300 millivolts and could instantly ignite objects. In addition, the laser pointer was the most harmful to the eyes because the eye was a lens. The parallel beam of the laser was focused on the retina through the lens of the eye. The energy density of the light increased by dozens of times, which could cause the retina to burn through and cause permanent damage. In short, the power of the laser pointer could not be underestimated.
