A computer-implemented method for validating digital signatures may include (1) receiving, through a camera of smart glasses, an image of an object, (2) decrypting, using a processor of the smart glasses, a digital signature on the object to obtain a decrypted digital signature, (3) attempting, using the processor of the smart glasses, to validate the object by comparing content of the object with the decrypted digital signature, and (4) outputting a result of the attempt to validate the object from an output component of the smart glasses. Various other methods, systems, and computer-readable media are also disclosed.
