Song Joong Ki Han Hyo Joo We reported a few weeks back that Song Joong Ki and Han Hyo Joo were spotted on set filming an "unidentified project" and now we can confirm that the two were shooting a contact lenses commercial for popular brand Acuvue.  The two were photographed on set smiling and looking playful, which was surprising, as it was revealed that the two had actually never met. A representative for the brand explained the brand's decision to hire each of them, stating, "Song Joong Ki has a unique gaze, and he demonstrated it in the movie A Werewolf Boy. He was recently chosen as the celebrity with the prettiest eyes. Han Hyo Joo also is a great actress with a confident and interesting gaze, as well as natural beauty. So we thought they fit Acuvue's image.” Acuvue 2 No word yet on when the commercials will begin airing, but we'll keep a lookout (puns!). These two definitely have beautiful eyes! Are there other Kdrama stars whose eyes make you swoon? Tell us in the comments below!
