If you are looking for just any brand of padded glasses, go to just about any motorcycle shop... also walmart sells some cheap pairs in there motorcycle section...
I broke down and bought the Bobster glasses for around $50 bucks at the motorcycle shop... They come with 4 different lenses (clear, yellow, light tint, and dark tint), a set of arms and a strap for if I want to turn them into goggles, two different foam pieces for around the eyes, and a nice soft case and a cleaning rag...
I like the Bobsters alot, but I work at night and go home in the morning, the changing of lenses got old, popping the clear ones out and the dark ones in every morning and night... I've taken to carring an extra pair of clear glasses for night, but other than that I love them.
Heres the pair I got...
