I was watching some dark shadows with a friend of mine and we had a discussion about Petofi's glasses I found interesting. These glasses were THICK, as Thayer David's eyes look enormous when he wears them. I'm not sure if anyone has ever put glasses like these on, when you don't need them, but they are very uncomfortable. Your vision is really blurry, it makes you feel dizzy, and gives you a headache. Not to mention, it causes long term damage to your eyes.
So did Thayer David need such thick glasses, or did he walk around barely able to see anything just for the sake of the character? That is devotion, lol.. I suppose it's also possible that the glasses were fake, but they do appear to magnify his eyes considerably, so I thought they were real.
