Liquivision claims that when you use their Nirvana 2 Fluid Goggles, you won't need "to waste precious air to equalize the mask and you will have more air to equalize deeper than ever before." I never considered that I was "wasting precious air" when equalizing, but maybe I'm missing something. Liquivision also promises that its masks eliminate mask squeeze, fogging, and flooding. I guess that's because, basically, when you're wearing a Nirvana 2, your mask is already flooded. Yup! Filled with saline solution, diving with the Nirvana 2 means that while you're eyes are open, they're touching liquid meant to "enhance your apnea reflex."

Featuring adjustable, removable, corrective lenses; a wide field of vision; and "greater thermal insulation against cold water," the Nirvana 2 is the only mask in the world that doesn't require equalization. Liquivision's Nirvana 2 Fluid Goggles run a hefty $295 per set, and they don't even include the required nose piece!
