This was introduced as a Sunglass Hut exclusive lens in 2000/2001 I believe. It does have a grey base lens that is slightly blue when viewing through. As with most Iridium coatings, I don't believe they effect what color you see as much as the base does. Not many companies were even using green at this point for lenses, I mean sure Revo had green glass and Bolle had something like this in the 90s, but it was a great first with Oakley. A few other companies had even intro'd green lenses after this had come out. Though named Emerald, it didn't show green like a true emerald. It was more of a Gold and Pale Green blend. A great overall lens though.

Although not quite as illustrious as the name suggests, Emerald Iridium still offers excellent contrast, beautiful color, and great protection. Truly this is one of the more versatile lenses that Oakley has created: somehow it seems to be well-suited for bright conditions, yet isn't overly dark on overcast days. Too bad the polarized version was extremely limited, as this would have no doubt made an award-winning combo with the Juliet.

When going for a green colored lens, emerald is not my first choice. I prefer the color and tint of jade iridium. The emerald inside and out is rather dull, good for sunny days and passable on cloudy days but if I had the choice I'd go with jade.

I'm a little torn on these. I have these in my carbon Juliet's which make an awesome combo, but the contrast is lacking. I know it's not meant to be a contrast enhancing lens, but these lenses seem a little more gry than other grey based lenses. I don't own too many grey based lenses, but I don't think I'll replace this. The color is awesome and maybe over time, I will get used to the greyish/bluish tint that these give off while looking through.

Love this lens. I have them on a pair of Jupiters. I do wish they were a *tad* greener, though. Haven't seen Jade in person yet. Looks like it may overtake the Emerald. Looking through it is great. A little darker than through Ruby. Just as much contrast.
