The U.S. versions of the color monitor for the Macintosh II and the Hi-Res
color monitor for the Apple IIGS do NOT have an anti-glare facing. UL, FCC,
and CSA standards do not require such facing.
However, these monitors ARE anti-glare faced for some European countries.
For example, Germany operates on the VDE standard which does specify an
anti-glare facing.
Apple decided that the anti-glare facing detracted from the sharpness of
the image on color monitors, and so specified that the anti-glare not be
place on the color monitors except in those countries where required.
Apple does not know of any U.S. agencies currently working on an ergonomic
specification of this type. Inside the US, the purchase of monitors with an
anti-glare facing, or the addition of an anti-glare filter, is currently
left to the discretion of the buyer.
Apple only performs reflectivity tests on those monitors which require
certification of the anti-glare face to meet a specific country's
requirements.
Current testing of the European monitors is done to meet the DIN 67530
standard:
15% - 75% reflectivity required @ 60% light incidence
20% - 50% reflectivity recommended @ 60% light incidence
