What? No one has a Hydro-Optix mask listed here? If you really want to see the underwater world the way it truely looks, you've got to try one of these. I've been using mine off and on since October. (Sometimes I just don't feel like changing my contact lenses so I stick with my older "tri-view"). Being able to compare regular flat lens masks versus dome vision masks, I am clearly convinced that there is no better mask when it comes to true vision. The Hydro-Optix masks have black or silver skirts so they don't let any back light in and they allow you to see almost everything in front of you without even moving your head. Yeah, they cost a bit more than regular masks, but, hey, my sunglasses cost more than this mask and it didn't stop me from buying them. Try one of these masks. See for yourself. You'll be amazed. My Mega DD -4.5 is definitely my favorite mask. I dive almost every day so I know what I like and I know what works. You owe it to yourself to at least see if one of these seals on your face. If so, take it in the water, you'll be hooked!
