There have been studies that have proven that the green lasers are more dangerous than red.
It's simply because the eye is more sensitive to light frequencies in the green/yellow range.
(that could/ probably DOES differ greatly in animals - I don't know)
So green is definitely more dangerous to humans. But add on top of that there are a lot of illegally imported green laser pointers with power levels way over what is considered safe.
Any laser can be harmful depending on the length of the exposure - stare directly into a red pen laser for an hour and it'll probably do permenant damage too.
Any time you see an after image from a light, you have at least caused some very minor "damage" -but it generally goes away in about 10 minutes.
If it lasts into days and weeks, you've definitely caused some more severe damage - but that hopefully will go away as it heels.
But if you got a good blast of green light from one of those illegal lasers (depends on how powerful) it can cause permanent damage.
