I have a 50mw with no IR filter. I realize that I could add one relatively easily, however I had a question about the nature of the excess IR. My understanding about what makes the green unsafe is that laser safety goggles are useless against it and it's invisible so the eye doesn't react to the IR to protect itself while doing damage. I know that since this 50mw is a class IIIB non-specular reflections should theoretically not cause eye damage without eye protection. I'm wondering, however, if viewing the laser green laser "dot" with IR is still eye damaging since by the above logic the eye's iris in shouldn't react and shrink to the same extent to deal with the full "brightness" of the laser like it would for a standard laser within the visible spectrum since a percentage of the energy output is invisible. Anyone know if this is actually the case as well?
