I have attached two pictures of my Oakley Crosshairs. These were originally purchased as non-prescription sunglasses a couple of years ago in the USA. Fast forward, I now need a prescription that includes x 4 prism measurements for long distance and driving. In addition to my crosshairs, I have several other Oakley sunglass frame types, so I trawled the web to see if I could buy prescription replacement lenses in the UK. Bingo, I found Posh Eyes. The website lists all of the Oakley frame types, it is a tick box exercise and it has various idiots guides to assist if not sure. I also uploaded my prescription and one of the Posh Eyes Team (Julian) even rang me to verify my prism measurement. My first order was for Transitions GEN 8 + Iridium replacement lenses, ordered circa Feb 2024, received them probably within five working days, Royal Mail Tracked, then within 10 mins I had my new lenses in the frame. I could not have been more delighted with the whole process and product, perfect fit and perfect prescription. Moving on, I ordered another pair of lenses on 1 Aug 2024, basically a reflection of the above, but Transitions Gen S lenses. What more can I say, I am equally delighted with the product and service.
