Please refer to Fig. 1, which shows the optical glasses 100 of the present invention. The present invention proposes an optical lens 110 comprising a rotating unit 113; a rotatable lens ηι; and a stationary lens 112. The rotating unit 丨丨3 is disposed on the optical lens 丨; [one end of the cymbal, for fixing a rotatable lens 1U and a fixed lens 112, and providing the rotatable lens 111 to rotate 36 degrees; The rotating lens lu is connected to the rotating unit 113 for deflecting the strong light; and the fixed lens 112 is disposed on the frame of the optical lens 11 () for use as a conventional optical lens 110.

The fixed lens 112 also includes a plurality of light diffractive elements 3〇〇; wherein the plurality of light diffractive elements 300 further comprise a plurality of order light diffraction unit cells 320. It should be noted that the polarization directions of the plurality of light diffractive elements 320 of the rotatable lens lu and the 亥 疋 lens 112 are 90 degrees of each other. Since light waves have a polarization direction, they are usually vertically polarized, horizontally polarized, or combined with vertical and horizontal polarization. Therefore, when the intense light is incident on the optical lens 11 () disclosed in the present invention, by rotating the rotatable lens 111, the glare can be deflected via the light diffractive element 3 , to protect the user's eyes.

After the invention of holography, the concept and principle of diffractive optics were further applied to micro-optical elements; such as beamsplitters and lens sets. The basic design flow of the light diffraction element is to first calculate the interference pattern of the specific wavefront, which is the computer-generated hologram (CGH), and then calculate the simulated interference pattern by the digital plotter output, and finally the miniature image. The film. The phase of the incident surface light field is modulated by the change of the surface profile, and the phase of the outgoing surface light field is controlled to obtain a distribution of the predetermined exiting optical space energy. Use Figure 3 to illustrate how to use it. Where λ ΐ, λ 2 and λ 3 represent three different incident ray rays, which are scattered by the light diffraction element. The design rule of the light diffractive element is roughly divided into four structures: the first is the optical path method; the second is the scalar diffraction theory; the third is strict The rigorous coupled wave theory; the fourth is the effective medium theory. The current light diffraction elements are mostly designed using a scalar wave diffraction method. The scalar wave diffraction method is based on the phenomenon of light fluctuations to describe the diffraction phenomenon of light, also known as fourier optics. The wave of light says that every point on the wavefront can be thought of as a secondary spherical source, that is, the wave packets of all new sources will form a new wavefront. The working principle of the light diffractive element is the equation of the relationship between the refractive index η of the medium and the film thickness of the light diffraction element. According to the wavelength of the incident light and the refractive index of the substrate 3 10, the optical diffracting element is not counted.
