Is a blue and violet laser more dangerous then any other color? And why

Questions, questions. A little appreciation would be nice for those who answer all your questions.

look at the keywords at the Tag Bar :D

Although green lasers only appear brighter because of our eyes, the energy of the beam is higher than the energy of the red beam.

The "5 mW rule" applies to classic red laser pointers only. The shorter the wavelength, the less powerful the beam must be in order to remain in the secure domain of a blink reflex.
I've read somewhere that rule of thumb is 2x the danger. That's why "<5mW green" is not safe unless the batteries are weak.

5mw is 5mw. The only reported incidents of eye damage from 5mw lasers of any color have all involved someone staring into the laser for extended periods of time.

Green is actually considered safer than red because it's more uncomfortable to stare into a green laser then a red one.

All I can say is.. they're your eyeballs. I'll personally continue to not shine lasers of any power at my face though, regardless of what anyone else does.

You can't equalize two wavelengths. Would you be fine with someone firing a 5 mW "vacuum UV" laser in your eyes (hypothetically)?

We're not talking about staring into the beam, but getting caught in front of one and shutting out eyes. Blink reflex is blinks reflex, its time doesn't change significantly with different wavelengths applied. I'd say it doesn't change at all but hey, there might be a minute statistically significant difference...

Are you sure about this?

Would a 5mw IR or UV laser even cause a blink reflex??
Otherwise, I'd have to agree with Ablaze, green should be safer as it is visibly brighter to our eyes.

Yes, anything outside of the visible spectrum would be dangerous at 5mw. Anything INSIDE the visible spectrum is only as dangerous as a McDonalds coffee. ie you can only hurt yourself if you try.

You're totally wrong about this. Because our eyes can't perceive IR our blink reflex doesn't kick in until we actually feel the burn damage that the laser is doing. Just the flash of a visible spectrum laser causes the blink reflex to kick in even if there is no damage being done. Now if we're just talking about visible spectrum than the difference in reaction time is negligible but green would technically be the "safest.
