Ghost hunter goggles

Ghost hunter goggles are part of the Ghost Hunter equipment. They can be bought from 6000 reward points during the 2014 Halloween event. They come in three levels: tier 1 is level 20, tier 2 is level 50, and tier 3 is level 70. You can change the level by right clicking the item.
