But such devices are not toys. Further eye damage can often linger for days or even permanently and can go unnoticed. This is why researchers working around lasers in research facilities such as LIGO the Laser Interferometer Gravitational Wave Observatory must submit to routine eye exams.
A laser reflected inadvertently off of an optical surface such as a car window or primary mirror can also do just as much damage as a direct aiming. There has also been an upward trend in individuals being tracked down and prosecuted for such offenses.
With this sort of news, we wonder if laser pointers might become outlawed entirely in the coming years.
