I bought some replacement sapphire iridium lenses for a 5 year old pair of Sliver XLs after reading good reviews here and elsewhere about the seller, Oakleyservices09. They seem like quality lenses, thickness is the same as the OEM (thicker than the $7 generics on eBay), optics are also fine as far as I can tell, but tint, and to a lesser extent color, are noticeably different. They seem to let quite a bit more light through. It seems unlikely to me that Oakley would change the tint this much, even five years later, but I don't follow this stuff. OEM is supposedly 12% visible light transmittance. Has anyone else noticed this type of change, on this or any other color lenses? Thoughts on authenticity? See photos, replacement is on the left side (as worn) when installed, right side in loose lens pic
