From Wikipedia:

Reportedly filmed in a marathon 30-hour session, the video was released in June 1984 and subsequently nominated for MTV Video Music Awards for "Best Editing" and "Best Cinematography". The video's extensive filming near fog machines, lighting, and fire sources nearly fused Idol's contact lenses. At the conclusion of filming, Idol attempted to leave, and promptly passed out on the studio lawn from exhaustion. Initially mistaken for a vagrant, a police officer who roused Idol was alarmed at his reddened eyes. The officer immediately brought Idol to a local hospital, where doctors were able to coax out the lenses, saving his vision.

Dang.
