I have come across what I think is an VR28 Strike M-Frame lens. However, where there is usually the "born on" date laser-etched on the lens, there is this:



Anyone know what "Z87 + S" might mean????

I think the Z87 is the ANSI safety standard? I may be way off though

Could be the Military/Industrial lens. Pre that little clip thingy.

yeah its the ANSI safty code that they meet

http://en.wikipedia.org/wiki/ANSI

The ANS for eye protection is Z87.1, which gives a specific impact resistance rating to the eyewear. This standard is commonly used for shop glasses, shooting glasses, and many other examples of protective eyewear.


What year are those?

I had never seen the "+ S" before, so I did a quick Google search and found this:

If I'm reading it correctly, the "+" indicates a High Impact Protection Level, and the "S" indicates a special purpose lens.

Hmmm, yeah I think you guys must be spot on with the ANSI stuff. Now it just makes me wonder if the lens is anything special ... or just a regular lens with the specific ANSI etching in order to be used and meet the safety lens market requirements. I think it is just a VR28 lens - maybe I will need to do some more comparisons from my collection to confirm. It just came through DE/Discontinued stock, here are pics of the lens:

It is. My guess is it came out of one of the Military/industrial arrays.
