Speaking with .uk, Henry Cavill says that a lot of dust from the volcanic rocks got behind his contacts and it almost didn't end well. Alas, while on location filming in the Canary Islands, things took a turn for the worse. The Witcher actor continued wearing the contacts without removing them as advised. You’ve got to take them out now.’ĭid he heed that warning? Not exactly, or at all. And I’ll say, ‘No, it’s alright we can shoot couple more hours will be fine.’ And she said, ‘We won’t be fine. I don’t care what you need to shoot, take, take the bloody contacts out, because you will start to go blind after a while.’ I was sure she was probably selling a slightly more dramatic version of the truth, because I do tend to be a bit stubborn like that. My eye-technician was always pushing me to say like, ‘No, I don’t care. Here’s what Cavill had to say regarding Geralt’s contacts and what his eye doctor told him would happen: However, as much as Cavill believed the contacts were fine, he was told that he should only wear them for a few hours at a time because there was a big chance they would blind him if he wasn’t careful. For his turn as Geralt, Henry Cavill had to wear colored contacts while filming The Witcher.
