A short summary would be to directly ask - 500mW entering an adult eyes would like cause a retina burn , my undestanding is the brain will compensate ,you may not even know you have been harmed .............. but what about childrens eyes ? ? ?
My thoughts on this are based around LOCAL DJs , huge amounts are buying lasers off ebay for their lighting rigs , as the prices have dropped they are now buying 50mW-250mW units ...what power will they be able to afford in 2 years time ..... 500mW ? 1watt + ??? I am working on the presumption here that these guys will treat lasers like every other light they buy and not be aware of consequences of laser light and be crowd scanning without even being aware of the dangers !
....... HEREs a thought , most of these LOCAL parties the local djs attend are family events with lots of children in attendance filling those dance floors ! wonder what effect a 500mW would have on a Childs Eye as against an adults eye !
