Yes indeed... It was Clark's glasses. (I did find the guess of Perry's toupee amusing, though!)
Malu, good question. I've often wondered where Clark's clothing goes. Most of it could, in theory, be folded up super-small and put into a cape pocket, but Clark couldn't do that with his shoes or his glasses.
Ya got me! Debbie Starks excellent, but incomplete, Dawning series has Clark putting them in hyperspace. It's as good an explanation as any I've seen.
Joy,
