To provide an anti-glare device for a vehicle that secures visibility of the outside of a vehicle and can further reliably shield light thrown to an occupant from the outside of the vehicle.SOLUTION: An anti-glare device for a vehicle includes: a liquid crystal sun visor 20 that can form a light shielding part for shielding light with electrical control; a first camera 11 and a light source detection part 41 that detect a light source on an outside of a vehicle; a second camera 12 and a position detection part 42 that detect positions of eyes of a driver; and a light shielding control part 43 for calculating a position where a straight line connecting a position of a light source to positions of eyes passes through the liquid crystal sun visor 20 and forming the light shielding part in the position.SELECTED DRAWING: Figure 4
