Shade Blade sunglass concept

The Shade Blade might not be the most aesthetically pleasing pair of sunglasses that you have set your eyes upon, but it comes with the interesting idea of adding a solar array visor on top, using sunlight to charge batteries which in turn powers a range of plug-and-play devices. Not only that, the designers claim that the future will bring tiny, interchangeable modules that come with different functions such as an AM/FM tuner, two-way radios, a cellphone, and even vision transmission technology. What is your idea of the ultimate pair of sunglasses? I know the Shade Blade doesn’t hold a place in my list, and for that I am thankful that it remains just a concept for the moment.
