Glowing Eyes

So I noticed a rogue who's eyes were glowing blue. I thought to myself, that's awesome and I want that.

I'm a mage, about to hit level 51 actually, but I'm not sure whether that's relevant. I did a little research and so far as I know there are a few ways to go about having your character's eyes glow; one being obtaining a certain set of weapons, another being have a particular buff (not sure which), and another by having a rare tanking necklace. I looked at the guy who had it and it was a rogue. He didn't seem to have any of these things. I thought it might have been his ascended power, but it was just the Defiant version of Omen Sight which doesn't give any particular effect.

So does anyone know where to get something like this? I figure if this was WoW I'd know instantly because I'm quite the items guru, but I'm back here on Rift after quitting soon after release and suffice it to say, my knowledge is limited when it comes to mostly cosmetic stuff. (I quit because I couldn't afford to play it and WoW. Now that it's free to play I can, yay!)

There doesn't seem to be an equivilent to wowhead - well there is, but it isn't as popular and so there's not as many comments, which is where I think wowhead can give you the most information. So any info would be appreciated.
