An automatic anti-glare device for vehicles includes: a transmissive liquid crystal panel disposed between a windshield of a vehicle and the head of an occupant; a sun detector that detects a position of the sun; an eyepoint detector that detects a position of the eyes of the occupant; and a controller that forms a light-shielding region in the transmissive liquid crystal panel based on a result of the detection of the sun detector and a result of the detection of the eyepoint detector. When the position of the sun on the transmissive liquid crystal panel moves in a range that does not depart from a stationary region virtually provided on the transmissive liquid crystal panel, the controller maintains the position of the light-shielding region.
