We have a Lazar light is it true that if you shine it in your eyes it can make you blind?

Question

WE BOUGHT A CAT TOY IT IS LAZAR LIGHT AND I CAUGHT MY GRANDDAUGHTER SHINING IT INTO HER EYES....THAT IS WHAT HAPPENED IT ONLY COST $4.00

Answer 1

depends. If you have a low powered one that you bought at a low price (40 bucks or less) if you shined it long enoguh at somebodys eyes (half an hour or more give or take 15 min)  you could burn the lens and cause serious eye damage. if you had a high powered laser ($150 or higher) you could burn somebody's eyes from a second to 5 minutes.

Answer 2

Any light, if it's intense enough, can make you blind...temporally or permanently, depending on the energy in that light.  Sun light for example, can blind you permantently if you stare directly into the Sun or if you are in a white reflecting environment like in a snow covered area.  (It's called snow blindness.)  My point is this, it doesn't take laser light to be dangerous.

New New Rule: don't let any direct or reflected light shine into your eyes when the source of that light is not well known or when the source of that light is known to be very intense.

By this rule, then, since you don't know laser light very well, don't let it shine directly or indirectly into your eyes...ever.  There is good reason why scientists working in laser labs wear filtering goggles when doing their experiments.  There is good reason why solar eclipse observers watch that effect by projecting the image on a screen rather than watching it directly through a telescope.

Answer 3

Yes, some lasers can render you blind, either temporarily or permanently depending on their power output. New Rule: Don't shine lasers in your eyes!!

Answer 4

It depends on the laser of course.  A pointer is barely going to dazzle you.  Some lasers could burn your entire eyeball out or worse.

Answer 5

never shine a object that bright into your eyes bad plan
