Video recording eyewwear has been around for years.. it is getting easier to use and the styling not so bulky.  Why be digging in your pockets and purses when you can take your Kodak Moments and make a click via your eyewear.

Not to be worn while in the water, but they do make sense if doing an event and want to have hands free.
