"🤿" is a word-based representation of a diving mask, which is a piece of equipment worn by divers to protect their eyes and nose while underwater. It typically consists of a tempered glass or plastic lens, a rubber or silicone skirt that forms a watertight seal around the face, and straps to secure it in place. The diving mask allows divers to see clearly underwater by creating an air space in front of their eyes, preventing water from entering and providing a clear field of vision.
