Abstract: The present invention relates to a process for gratings able to resist dizziness, enhance color displayed, eliminate static electricity and block radiation. Steps included are: making a substrate with an enhanced glass or optical plastic glass or optical plastics; coating the surface of the substrate with dizziness-resistant films composed of evenly distributed nano-particles, wherein the inner layer is made of Cu particles or Al particles and the outer layer is made of Cr particles; forming a static-electricity-resistant layer on the grating's surface so as to form an optical diffraction grating able to resist dizziness, enhance color displayed, eliminate static electricity and block radiation.
