A helmet with an optical display system is provided with a custom fit protective liner which precisely aligns the wearer's eyes with the optics on the helmet. The helmet is manufactured by positioning the subject's head in a fixture; determining the position of the subject's pupils with respect to the fixture; scanning the subject's head with a laser while positioned in the fixture in order to obtain a 3-D model of the subject's head; and providing a helmet liner having an outer surface which is profiled to position it inside a helmet shell. The position of the subject's pupils may be determined by scanning pupil locating features of the fixture. The 3-D model is then used to provide the helmet liner with an inner surface which conforms to the subject's head and is positioned with respect to the outer surface so that the outer surface will have a predetermined position with respect to the subject's pupils. The helmet liner is then fitted in the helmet shell to form a helmet. The helmet shell may thus be fitted with pre-positioned optics which are properly positioned with respect to the subject's pupils.
