The invention discloses a device and a method for preventing vehicle headlamps from glaring. The problem of distance light glaring of the vehicle headlamps is solved by controlling the switching frequencies and phases of headlamp light sources and shutter type lenses. Intermittent luminescent light sources switched rapidly are used as the headlamp light sources, and simultaneously the shutter type lenses switched rapidly are matched for use. The switching frequencies and phases of the headlamp light sources and the shutter type lenses are controlled to solve the problem of distance light glaring of the vehicle headlamps. According to the device and the method disclosed by the invention, vehicle traffic accidents can be prevented and reduced, vehicle deceleration and acceleration caused by light glaring in vehicle meeting are reduced, electric energy consumed by the headlamps and heat generated by the headlamps are reduced, and the service life of a product is prolonged. The device and the method disclosed by the invention have good social, economic and environmental benefits.
