Hand holding a laser pointer
Laser pointers are small, hand-held devices whose pointer emits a light at a wavelength of 670nm to produce a narrow beam of red laser light which can be directed over long distances. While originally designed as educational and business tools, laser pointers are now marketed as toys which increases the risk of safety incidents.

As kids, we used them to disturb a class presentation, tease our pets, or re-enact Star Wars. Little did we know, these handheld tools can cause serious eye damage.
