They could be blueblockers - they are wraparounds that cut out glare but wraparound - you can also get yellowblockers - I have these but they look yellowy on the outside - but the guy on SG1's look darker - which is why I thought blueblockers
I got a similar pair years ago in Carnaby Street before it went to "rave/dance" wear and way before it was "gentrified". (Cheapo knock-offs, obviously). Try your local Goth/alternative wear shop.
The official SG!1 site identifies them as "Bugaboo glacier glasses by Bolle". I have been trying unsuccessfully to find them online. They would be nice to try as I mostly wear Julbo glacier glasses with the side shields. If anyone is able to get more info please share.
