Is looking into a laser beam harmful to the human eye?!
Question: I have a question for professionals in eye care.
I recently purchased a happy meal that contained a toy that shines a little red laser light. It comes with a special lens with what appears to be a grid in it. The child is supposed to hold the lens to his or her eye and shine the laser light directly into the lens, which does not reduce the intensity of this bright little light. I tried the toy to find out what the children were looking for (they are supposed to see smily faces every where), but I saw nothing and after about 2 seconds I developed a mild headache that lasted one hour.
Questions:
Is looking into a laser beam harmful to the human eye?
Does a lens that breaks the single beam in to hundreds of smaller beams help reduce the harmful effects?
Should parents of epilieptic children be concerned?
Please advise opthamologists and the medical community of this concern, if it is warranted.
Thank you.

It's probably not a laser light but just a little light emitting
diode.
i'm not an eye doctor but i took physics in college and i'm a geek who always wanted a real laser but never wanted to pay the 50$ or more for it.
your toy is a little red light. it is not a laser. lasers are espensive, and not given out for free. the difference is that you can shine a laser for miles and it will not dissipate, it will still be a little point. i bet you 100$ that if you shine your kid's toy, it will be a wide red dot at 2 inches from a wall, and totally invisible from 10 feet away. if you shine it at a wall from ten feet away, you will not see a laser dot. you will see nothing becuase it is a toy light made to look like a laser. if you shine a laser at a wall 100 feet away, it will still be a little laser dot. that is why they use them for sights for guns.
lasers can cause blindness. since you are an adult and you don't even know the difference between a toy light and a lasar(keeping my thoughts about USA public education to myself here) it's probably not a good toy since it may make children make the same mistake and later shine some geek's real laser pointer (you know, the one i always wanted) into their eye. i saw a kid who thought root beer was real beer. so... shine a "laser" into an eye toy.
LMBO ...great answer, Mockingbirds !
That is priceless !
