Actor Joo Won's eyes have become a hot topic online.

On February 2, fans and netizens discussed an alleged change about his eyes on online community 'theqoo' under the title "Joo Won's right eye has lost its double eyelid, so he only has one eye that's a single eyelid now." It's known among fans that the top drama actor underwent cosmetic surgery for double eyelids during his college years, and in photos from his teens, he's seen with less pronounced double eyelids or just single eyelids.

Following his acting debut, Joo Won changed his double eyelids to be more pronounced, and that's what viewers have been used to until recently. Netizens are speculating he either reversed the surgery or his eyelids naturally returned to their normal state.

Either way, fans and netizens are loving the change, commenting, "Single eyelids are better," "It's so charming how he only has one single eyelid," "This is better," "I like it more," "He really looks like Kang Dong Won," "He has single eyelids, but his eyes are big. I loved him in 'Stealer'. I love Joo Won."

In other news, Joo Won is starring in the upcoming ENA series 'Nightly Photo Studio', which is expected to premiere in March.
