> Cheap laser pointers often skip the IR filter and will pass through a lot of IR light— which is especially dangerous because it doesn't trigger the blink reflex.
This is just outright wrong.
IR lasers don't trigger the blink reflex. Visible lasers with an IR component do trigger the blink reflex.
You're right about that part, though I've read that since the IR refracts differently than the green, you'll wind up with a region where you're directly exposed to the IR but not to the visible light.
