HAHA in that picture with the crazy green laser it would be funny to see those picture frames break apart afterwards....then the drywall...then the foundation...then a car crahsing noise in the background...HAHA
anyways, nobody be worried about your retinas being damaged by regular laser pointers. they are a regulated class one laser or "light amplification through stimulated emission by radiation" which has a blink factor lower than the human eye, your Human eye will protect itself no matter what, Unless boddily impaired with your eyes held open with dialated pupils..Dont mess with the laser master!
These lasers are class three laser becuase they produce thermal effects and can physically harm skin and do retina damage, therefore you must be 18 yo own one
Any more powerful and you would need to have a wall surrounding you with a ceritifed locking mechanism followed by another room with another certified locking system with rediation treatment on the surfaces and a "laser inside" light active whenever the laser is physically active
