This isn't considering IR leakage from DPSS green lasers though, which is a totally different problem that has nothing to do with the sensitivity of the retina. That just depends on how crappy the laser pointer is.

Everything you said is true, but it doesn't change my point, which is that opthalmologist has no idea what she's talking about :-) In practice green lasers sell because they're bright, and they crank up the power because everyone wants moar bright, and that's all there is to it.

Meanwhile your typical cheap presentation-style pointer is still going to be a 5mW red, which is fairly safe. Consumers want either cheap "normal pointers" or "stupid bright eye destroyers"; the former are almost universally red, the latter usually green.
