The invention relates to a method for manufacturing light bullet-proof glass. The method is characterized by comprising the following steps of: processing raw material glass sheets and organic glass plates into products with required specifications, cleaning and drying; sequentially laminating a panel glass sheet, a polyurethane film, an organic glass plate, a polyurethane film and a back plate glass sheet so as to obtain a combination material; putting the combination material on a flat press for pre-pressing; and feeding the pre-pressed combination material into a still kettle for steaming so as to obtain the light bullet-proof glass. The polyurethane film with high toughness and high penetration resistance and the organic glass plate replace a middle glass layer of the conventional bullet-proof glass, so that the impact resistance and penetration resistance of the glass are enhanced, the weight and thickness of the bullet-proof glass are reduced effectively, cost is lowered and the overall dead weight can be reduced by about 20 percent; simultaneously, the rigidity and intensity of the inner and outer sides of the bullet-proof glass are kept the same as those of the conventional bullet-proof glass.
