A New York teen lost vision in his left eye moments after powering up a "defectively designed," Chinese-made laser pointer he purchased on Amazon, according to a lawsuit against the retail behemoth.
Red (635 nm), blueish violet (445 nm), and green (520 nm) laser pointers. A laser pointer or laser pen is a (typically battery-powered) handheld device that uses a laser diode to emit a narrow low-power visible laser beam (i.e. coherent light) to highlight something of interest with a small bright colored spot.
Thus, it appears that a brief 0.25-second exposure to a <5 mW laser such as found in red laser pointers does not pose a threat to eye health. On the other hand, there is a potential for injury if a person deliberately stares into a beam of a class IIIa laser a for few seconds or more at close range.

For the several speeches he had to give, Mullis had brought with him a pen-size laser to use as a pointer. In a playful mood one day, he started aiming the red dot of light at passersby below his ...
Laser types with distinct laser lines are shown above the wavelength bar, while below are shown lasers that can emit in a wavelength range. The height of the lines and bars gives an indication of the maximal power/pulse energy commercially available, while the color codifies the type of laser material (see the figure description for details).
