the CDROMs and burners I saw are class one devices:
-----------------------------------------------------------------------
_Class 1:_
Class 1 lasers are the lowest powered lasers and considered "harmless" unless tampering with the device has occurred. An example of a Class 1 laser product is a CD-ROM player.

one should look at the label for each device ...

damage is nasty, but not always irreperable (in the extreme one can implant a lens or cornea)
(I saw in a previous job a man who actually shot his own eye with an air-gun.
His CT looked to my untrained eyes as quite a mess, but the retina wasn't hurt,
so the technitian said the doctors will probably fix it, which they eventually did.)
visible and IR-A pass thru the lens like a hot knife thru butter, they can then cause retinal (neuronal)
damage. This is AFAIK irreperable blindness. As in blind for life.
AFAIK cd-drives are red wavelength, but their power is small. However,
I wouldn't bet my eyes on it.
1) glasses are no reliable protection against visible-light laser.Even that is not too bad since I am wearing glasses... Looking at the light of a Xerox machine is probably worse.
2) glasses are reflective. If a hazardous laser bounces of from them it can hurt someone else .
