Polarized etching on lens

[djmiles1234]

I bought a new pair of oakley flak jacket xlj polarized on ebay and I received them yesterday and can someone please tell me what side of the lens polarized is etched on. Like the front or back side. I thought it was on the front but these are on the back

Usually always left lens as you wear them. Never seen the etching on the right lens as you wear them.

Think it was lenses that were custom

I've seen several etched on the backside. GIVES ME AN IDEA!

I want to say I had a pair of FIP that was etched on the inside.

Yeah I think most of the ones I’ve seen were FIP
