The FDA approved the world's first fully transparent surgical mask, according to CNN.
Three quick notes:
1. American medical supply company ClearMask manufactures the newly approved product, which makes the mouth visible.
2. The mask is intended to help individuals who rely on lip reading because of hearing impairments, as well as to facilitate conversations between people who don't speak the same language.
3. Designed to offer a high level of protection, some models of the mask are approved for use in operating rooms.
