An anti-glare device for reducing night-time road glare includes an anti-glare panel for attenuating and/or filtering light traveling from a source of glare through the panel to a driver's eyes. The anti-glare panel is secured to a sun visor of an automobile via an attachment mechanism comprising an elastic member, which compresses around the sun visor. The anti-glare panel attaches to the elastic member via attachment arms of the anti-glare panel that are folded over and secured, forming loops through which the elastic member is threaded. The attachment mechanism can further comprise a secondary elastic member for holding the anti-glare panel in an inactive position when the device is not being used. Additionally, the horizontal width of the anti-glare panel can decrease over the panel's vertical length, forming a recess at the panel's bottom corner for allowing natural visibility of a center line and/or lane markings of the road.
