What defines a Class 2 laser regarding its power?

A Class 2 laser is defined by its power being greater than 1 milliwatt (mW) but less than or equal to 5 mW. This classification reflects the laser's potential for causing eye injury during direct exposure; however, it also recognizes that Class 2 lasers are usually considered safe during normal use due to the human eye's natural aversion response to bright light, which generally leads individuals to look away or blink when exposed.

Choosing a power level of less than 1 mW does not accurately capture the parameters defined by the Class 2 laser category since this range does not align with the established guidelines of laser classification. The other options similarly misrepresent the characteristics and classifications of laser power concerning safety and risk, as Class 2 lasers fall within a specific range for precautionary measures due to the exposure risks associated with their output power.
