Hi everyone, I've been reading many posts on the forum but still had some questions so I decided to sign up and make my own thread. I bought the Pitbull glasses based on some reviews I read here on the forum and they are great! I just got them last weekend at my local O-store and have been wearing them now for about 9 or 10 days. At first I wasn't sure I'd like them but the fit is great and I absolutely love the stems and nose with the Unobtanium, a nice grippy fit even when sweating in the sun. I went in thinking I'd get the Straight Jackets but tried them on and they are pretty small for me (got a large dome) and a lot of light comes in from underneath. So I bought the Pitbull in matte black frames which are awesome looking, but only available with the Warm Grey lens. Well this lens is not cutting it for me. I have very sensitive eyes and with this warm grey lens I still end up squinting sometimes while wearing these glasses in the bright sun. So, my first thought was to go back and exchange the glasses for another Pitbull with Black Iridium lens hoping they'd be darker, but from searching the O site I see that the only lens offered with the Matte Black frame is the Warm Grey, and the Pitbull lenses are not available separately. So I have a couple questions for you experts: 1. I checked out the lens tint app on the O site and it lists both Warm Grey and Black Iridium as 10% light transmission, so this means they are the same in regards to the amount of light that passes through, is that right? I need the darkest I can get in reference to what I see when the glasses are on my face, so in real life are the Black Iridium lenses actually darker as compared to Warm Grey? Does anyone have real world comparison on these two lenses? 2. If the Black Iridium lens is darker and I decide to get those then I'll have to get the Polished black frames which are decent but I really like the Matte Black frames. Does anyone expect the Pitbull lens to be available separately anytime soon? I notice it is not customizable on the O website, is that because the Pitbull is still shown as “new” on the O website? My point is that I would like to keep my matte black frames but get a darker lens than the Warm Grey, if that's possible? Any ideas? Thanks for reading this everyone, I appreciate your advice!
