the.com/vanity mirror

means A mirror mounted at a dressing table or car visor, usually ringed with flattering light, made for grooming and checking your face rather than seeing your whole self.

from Pairs two old threads: 'mirror' from Latin mirari, 'to wonder at,' and 'vanity' from vanus, 'empty' — via the medieval vanitas tradition that painted mirrors and skulls together as reminders that beauty and self-regard are fleeting. 'Vanity table' furniture emerged as a named piece in the early 20th century, and when automakers tucked a small mirror into the sun visor, they borrowed the same word — a little station built purely for looking at yourself, empty of any other purpose.
