Description

Technical field [0001] The invention discloses a method for preparing an anti-glare film material, which belongs to the technical field of building materials. Background technique [0002] Glare is an important factor affecting vision, and it is related to the position and brightness of the light source. There are many potential glare sources in daily life and work. Glare is a serious light pollution such as the glare reflected by the glass curtain walls of tall buildings in modern cities, which causes visual disturbance to pedestrians and affects the normal rest of the surrounding residents. The glare generated by the roadside lighting decoration and night lighting sources will cause sudden emergencies. Temporary blindness and illusion of vision can instantly obscure the driver’s vision or make him feel dizzy, which can easily lead to traffic accidents. The glare is mainly caused by the angle between the position of the light source and the viewpoint. The extremely bright lig...
