0431 is the Oakley Crossrange Shield in Grey Smoke with PRIZM Ruby and 0531 is the same model but in Matte Transparent Blue with PRIZM Sapphire. Both lenses are great medium tints that will get you by in a variety of conditions. The performance function between these two frames is very similar. The main difference is aesthetics. Thanks for reaching out!
The Crossrange shield is not available in rx because it is a single lens. Adding an rx to a lens of this shape has not yet been mastered by Oakley engineers. The standard crossrange is available in rx though! Thanks for reaching out!
Hi Simon! While both of these models have since been discontinued, the crossrange patch is approximately 147 mm wide and the single shield lens version is approx 150. hope this helps some!
