Hi everyone, Since you are all fonts of information, I wanted to ask about Ruby Clear Iridium. It seems to be a very rare tint, and maybe somewhat discontinued. The threads I read talked about it for goggles, and some for very low light conditions and indoor. It seems to be just a clear lens with a light iridium coating, which would make sense for an indoor sport with bright lights like volleyball, racquetball, basketball or hockey, arena football, but I'm just guessing. What was this tint originally made for? What is it good for? And are there any models in recent years where ruby clear was or is a replacement lens option?
