You'd be best to email the companies in question Greg and ask for some info about the lens. Although as they're both around the 12 to 13 quid mark you have to have doubts about the quality of the lens.
They just replied to my email. They're not UV lenses
Well, the seller seemed legit, and add stated that 10% of the sale would benefit families of WWII veterans, but of course that could be a gimmick. It was listed at $225 and I offered $150 which was declined and then $170 which was accepted. Immediately afterwards, I was kicking myself for not checking here for authenticity before buying (as I know nothing about WWII sunglasses except for the little I've found online). They are definitely wearers like the seller stated, but maybe I paid too much (although in that condition and if they are authentic, I think they're well worth $170).Wow! Tjoenn! If those are repros then they are the most authentic looking ones I’ve seen and I want to know where to buy them! They look legit, have the correct shape and if authentic you have one of the finest pair ever found! Hope you got a nice deal on them but they look worth the money.
I have one repop of these made under the Lindbergh name. (I have never seen a pic of Lindy wearing sunglasses of any kind.)I have three pair of 1930s wire Willson Sunglasses.
