I dive with the SeaVision mask. It has the color corrective lenses. It is TOTALLY legitimate. Most of my diving is in CA where with a regular mask the diving seems green and gray. When diving with the Seavision mask (with the rose-colored lenses)California diving is colorful. You cannot believe it until you try this mask. It really does allow you to see more color. On top of that it is a great fitting mask. It has a very soft silicone skirt.
