I saw that the17thman has a post that looks like a preview of what blueseventy is calling their Carbon RZR goggle. I started writing comments on his post, but after paragraph #2 I decided to just create my own post to serve as my response.
The “RZR”? I’m getting sick of the SMS-themed brand names. Short isn’t always sweet. Maybe I’ll take some merchandise on the road and sell LZR’s and RZR’s out of the back of my TrailBLZR. Ok I don’t really mind it that much, I just wanted to say “TrailBLZR”.
The wrap-around gasket looks pretty revolutionary. It looks like it would definitely redirect water to flow up and over the goggle rather than pushing through it. This is the kind of thing I predicted would happen with a lack of restrictions placed on goggles and caps. Suits have been getting all the attention, without some new restrictions I’m predicting egg shaped dome caps and goggles that ‘smooth over’ the entire concave eye socket.
The texture of the gaskets on these goggles is also interesting. They have a series of perpendicular lines that look like they are meant to interrupt laminar flow rather than preserve it. I would imagine that this has an intended purpose similar to golf ball dimples, where the dimples actually creates a turbulent boundary layer.
If you want to get technical:
“The transition to a turbulent boundary layer, adds energy to the flow allowing it to remain attached to the surface of the sphere further aft. Since separation is delayed, the resulting wake is much narrower. This thin wake reduces the low-pressure region on the rear face and reduces the difference in pressure between the front and back of the sphere. This smaller difference in pressure creates a smaller drag force.” (source)
The same principles apply to the old TYR Aquashift that had turbulent ‘trip wires’ that caused turbulent flow to surround the suit, delaying flow separation.

Then again, maybe it’s just a cool pattern in the gasket. Whether or not these perpendicular hash marks are intended to decrease drag by increasing turbulent flow surrounding the goggles, I think goggles still have a lot of tinkering room left in their design.
Update: In the time it took me to write this, Joel has posted more photos of the blueseventy Carbon RZR goggle.
12/16/09 latest update from Joel, these goggles will retail for around $100!? What? Read more from the17thman. Apparently the Carbon Fiber Polymer is incredibly light and strong? The new release has less to do with the shape and texture than it does with the material itself.
