Hrm... "smart" sunglasses usually means they have some sort of tech built into them, as simple as a basic MP3 player, to more advanced military grade sunglasses which turn into "nightglasses" at nighttime (think nightvision), or heat/IR sensing modes that can be switched on the fly.
Just as "smart"-phones gradually became increasingly more mainstream and acceptable as a societal norm over the years (heck, it's hard NOT to upgrade your mobile phone to one that isn't "smart", sports a dual-core 1+ GHz processor, and basically mimics everything a PC do except... in the palm of your hand, "smart" sunglasses could follow, I stress, COULD follow the same trend and become the mainstream and standard design for all sunglasses in the years to come.
From those pictures it is really hard to tell what make they are, but a simple Google search for "smart sunglasses" might yield some (probably pricey) results, unless they're just the stupid MP3-capable ones.
