I saw the green on His face too, it was on tv so it should be looked into.

Wether it would blind him or not is not the point, these things are banned and if it was us doing it you would read about it on the front pages.

From Yahoo answers-

Q - Can a standard pointing laser make you go blind?

If a standard pointing laser is pointed directly into ones eye, will they go blind? I've always heard this is true but I'm not certain about it.

A- The short answer is yes, but it would be difficult to do.

A standard laser pointer is limited to be under 5 mW of light power. The damage threshold for the human eye is about 1 mW. So, since 5 > 1, a laser pointer can damage your vision. However, your eye has some built in safety mechanisms. In particular, you have a reflex to blink and look away when you see a bright light. The time that it would take for a 5 mW laser to do damage is longer than the time it takes to blink. So you would likely blink before any permanent damage was done. That is why laser pointers are considered to be relatively safe: because your blink reflex will save you. However, if you suppress your blink reflex and stare into the laser, it can certainly damage your vision.

The reason laser pointers are not generally more powerful than 5 mW is because above 5 mW, the damage will occur faster than you can blink. So if you ever come across a laser pointer with more than 5 mW, you should be very careful (all laser pointers are labled with their power).

Green laser pointers are usually infrared lasers that are double to green. However, if you have a cheap (and illegal) one, it may not have an infrared (IR) filter, so some IR light may leak out with the green. That is especially dangerous for two reasons. First, to get 5 mW of green, the laser will need to make more than 5 mW of IR. However, IR light can burn your eye just like visible light, so more than 5 mW of IR can and will do damage to your visions. Second, your blink reflex does not work for IR light because you can't see it. So you could stare happily into an IR laser without even knowing it until your vision started to decrease. Now a legal green laser will have the filter that removes any left over IR light. So this is only an issue if you buy a cheap laser or if you are disassembling your laser pointer. You should also be very careful if you are disassembling a CD/DVD/BluRay player, as all of those also use lasers that can damage your vision. In the case of CD and BluRay, the laser beams are invisible (IR and UV, respectively) and for a DVD the lasers are simply more than 5 mW. So playing around inside of a disc reader should only be done if you know what you are doing.
