minus-squarezqps@sh.itjust.workslinkfedilinkarrow-up11arrow-down2·9 months agoA laser that can kill a fly in the fraction of a second has to deliver enough energy to fry your retina even though a dozen sunglasses. Also consider that the laser is focused down by the lens in your eye which greatly amplifies its power.
minus-squarearamova@infosec.publinkfedilinkarrow-up13arrow-down1·9 months agoThat’s not how specific wavelength safety goggles work. You can get both near UV blue light 440nm 5 watt goggles, and infrared depending on the laser. Problem is they tend to shift the color of light for everything so much that they aren’t pleasant to wear for a long time. My worry would be getting hit on the skin, a 5 watt 440nm laser hurts, and it’s a deep burning pain that doesn’t go away.
