Went to get mine renewed for the second time last year.
My advice - you can get your eyes tested outside the traffic dept - but it's usually just best to rock up early before it opens up. It still means standing outside for 30 minutes (in the cold usually) but at least once the doors are open you're in and out in about 15 - 20 minutes.
Our traffic department had the fingerprint scanner by the eye-testing machine as well
