Singer BoA revealed a self-taken photo.

"How many hours have I been sitting in front of the computer now...," Boa updated her Instagram on March 2. "Have you heard of the blue light lens? These really help my eyes not get tired," she went on to caption her photo.

"When will my work end wow it's already past ten yes, I can focus only when I put on ugly glasses. I'm a working woman," she stated.

In the picture, BoA is wearing big round glasses as she looks at the camera. She seems to have been working for a long time, as she appears to be tired.
