Green laser pointers: Playing with danger
High-powered lasers are dangerous and can cause severe eye injury. This image from the FAA shows eye damage from lasers. Even Class IIIa, laser pointers can cause temporary visual effects causing short-term blinding and disorientation.
The high-powered pointer below was listed for sale online. The Class IIIb laser has 50 milliwatts of output power, 45 milliwatts above the legal limit of 5 milliwatts, for a laser pointer.
HAVE A QUESTION ABOUT A DEVICE
Contact the FDA's Center for Devices and Radiological Health at (240) 276-0326. Some laser pointers purchased online do not meet federal safety guidelines. They may have lasers too powerful. The FDA has more information.
CLASSIFICATION OF LASERS
Green lasers are used in:
Class I: CD players
Class II: Bar code scanners
Class IIIa, less than 5 milliwatts: Laser pointers and some gun targets
Class IIIb and IV, more than 5 milliwatts to 500 milliwatts: laser light shows, industrial lasers, research lasers.

As the owner of the site you have a picture and link to.
I feel compelled to let everyone know that we have many informative posts on safety on our forum as well.
Its a shame as with most things that can be dangerous, there will always be those who are irresponsible and those who spin information so its viewed as a negative rather than the enlightening hobby that it is.
As the old saying goes... Guns don't kill people, People do.

It's very dangerous of pointing the laser pointer to people's eyes.

I agree with this some high power laser pointers are very dangerous if you pointed it into an eye.. You must read the user guide manuals on how to use the proper way in your laser pointers.
