Has anyone noticed that the lens for the EB1 maxvision seems to not be tinted, meaning it does not have an anti reflective coating on it? The lens even seems like its plastic but I know it isn't.
Didn't notice but I believe you are right. Also, is the E1B-MV lens slightly convex on the front surface? Most of the small Surefire lights seem to have coated lenses but I did find an old EB1-C in the drawer with an apparently uncoated lens.
When I try to compare the reflections off the front surface of the glass in these lights, the image from the E1B-MV appears smaller leading me to believe that the lens is slightly domed like many wristwatch crystals. Looking at the MV lens with magnification I can see some Newton's rings around the periphery where the glass meets the edge of the reflector.
And, with watch crystals, sometimes both sides of the glass, acrylic or sapphire are coated, sometimes only one side is. For example, the early version of the Omega X-33 'Mars Watch' had both sides of the domed sapphire crystal coated but it was a real fingerprint magnet. The next version had only the bottom surface of the crystal coated. I've got both versions of the watch and I can see the wisdom of the change.
