> A laser can damage eyes and blind people.
A <1mw pointer is fairly safe all around. Some $15 ebay lasers have real risk of temp retina damage at arms length. Lasers in the $150-$400 dollar range can do real damage fast under 30'.
Much more powerful Chinese military dazzlers are intended to incapacitate (not blind) at hundreds of yards.
>If shined into a heli it is VERY dangerous.
True. Aircraft are very vulnerable. Fifteen dollar ebay lasers are an absolute menace to night vision at hundreds of yards.
- nom 3y agoAny ebay / china laser can be unsafe. I did some test orders in Germany and 2 from the three 'high power' lasers I bought for less than 10 euros were easily over 100mw, and are even labeled as 200mW and 350mW. Very illegal to sell to consumers, but no one is checking. Ebay kicks the listings if they mention the power, so they just.. don't mention it. Buy a "high power laser pointer" and chances are you actually get one. They diodes are dirt cheap. Even at way lower output power you will damage your eyes by just looking at the dot on a wall. Use it indoors and all it takes is one unlucky reflection on a shiny object and you will wake up to a detached retina the next morning.
- smsm42 3y agoIf somebody is using a laser in a protest, we can be pretty sure they're not doing it to highlight the main points in their powerpoint presentation "How to Peacefully Protest for Fun And Profit". Trying to blind cops & helis with laser is a known riot tactics, and pretending we don't know what's going on is not very useful.
