Default Re: Unfocused Laser Strikes Cat , reflection strikes me in th eye

if it really looked like a flashlight then there is no danger, even to the cat, lasers are only dangerous because energy density say you have 1000 units of light, a laser puts all that in a square cm, a flashlight makes it over 1000 square cm...

Your eyes should be fine, chances of sufficient exposure to cause damage, from the reflection off of the eyes of a cat at 10m, from a laser beam that is already defocused... you got scared and/or slightly flash blinded that's it.

About cat eyes kind of glowing/reflecting light, read up: Tapetum lucidum - Wikipedia, the free encyclopedia

Well.. I guess an unfocused, uncollimated laser at distance is pretty much like a flashlight ,only with coherent wavelength right?

So.. I screwed the focussing lens off and shone it at the UMO (Unidentified Moving Object)

It turns out it was a cat at around 10m away, when I was about to turn it off, the cat turned towards my position and its the light strikes it in the eye and then reflected right back into mine.

Getting a bit of the faint flash blindness at the moment.
Should I be worried?
