The invention provides a blazed 5D colorful beautiful pupil, which comprises a beautiful pupil body matched with the curved surface of an eyeball; the cosmetic pupil body takes the center of a spherical surface as the center and comprises a central spherical surface area, an annular spherical surface area and an edge spherical surface area along the direction extending outwards; the inner curved surface and the outer curved surface of the beautiful pupil body are smooth; the cosmetic pupil body sequentially comprises a first semi-absorption layer, a first film layer, a reflection layer, a second film layer and a second semi-absorption layer from inside to outside in the thickness direction; the surface of the annular spherical surface region corresponding to the reflecting layer is provided with convex dots, and the convex dots are embedded in the second thin film layer; the thickness of the second film layer is greater than or equal to the height of the raised dots; the raw material for preparing the reflecting layer is photochromic ink. The arrangement of the convex dots in the blazed 5D colorful beautiful pupil utilizes the interference effect of light rays, so that the light waves are reflected by the upper interface and the lower interface respectively, and finally interfere with each other to form new light waves; meanwhile, because light is a wave, light waves with different colors have different wavelengths, and meanwhile, due to the fact that the thicknesses of the reflecting layer and the absorbing layer are all uneven due to the arrangement of the convex screen points, different reactions such as emission and absorption can occur, and different colors are presented. Therefore, when the blaze 5D colorful cosmetic pupil performs light irradiation, light with a specific wavelength is reflected according to the law of reflection, and the color of the blaze 5D colorful cosmetic pupil also presents different colors according to different viewing angles; for example, when the blaze 5D blaze cosmetic pupil is viewed vertically and appears in a first color, and when the blaze 5D blaze cosmetic pupil is twisted by 60 degrees until the line of sight is at an angle of 30 degrees with respect to the lens, the original color will destructively interfere and disappear, thereby forming a color different from the first color (as shown in fig. 2).
