Embodiment 1

[0029] Such as figure 1 As shown, the moisturizing radiation protection contact lens of the present invention includes a lens body 4, the surface of the lens body 4 close to the eyeball surface is the inner surface 2, and the surface of the lens body 4 away from the eyeball surface is the outer surface 1. The average thickness of the lens body 4 (ie the vertical distance between the outer surface 1 and the inner surface 2 ) is 1.5 mm. The inner surface 2 coincides with the curved surface of the eyeball, and the curvature difference between the inner surface 2 and the curved surface of the eyeball is 1 nm to 1 mm.

[0030] The entire inner surface 2 is covered with a reflective layer 3 with a thickness of 1000nm~3000nm. The reflective layer 3 is a reflective paint coating that can reflect electromagnetic waves with a wavelength of 400~2500nm. The refractive index of the reflective layer 3 is 0.87.

Embodiment 2

[0032] Such as figure 2 As shown, the moisturizing radiation protection contact lens of the present invention includes a lens body 4, the surface of the lens body 4 close to the eyeball surface is the inner surface 2, and the surface of the lens body 4 away from the eyeball surface is the outer surface 1. The average thickness of the lens body 4 (ie the vertical distance between the outer surface 1 and the inner surface 2 ) is 2mm. The inner surface 2 coincides with the curved surface of the eyeball, and the curvature difference between the inner surface 2 and the curved surface of the eyeball is 1 nm to 1 mm.

[0033] The entire outer surface 1 is covered with a reflective layer 3, which is a reflective paint coating that can reflect electromagnetic waves with a wavelength of 100-2500nm. Table 1 is a relationship between the thickness of the reflective layer 1 and the refractive index, wherein the reflective layer 1 corresponding to each number is sprayed with the same refl...

Embodiment 3

[0037] Such as image 3 As shown, the moisturizing radiation protection contact lens of the present invention includes a lens body 4, the surface of the lens body 4 close to the eyeball surface is the inner surface 2, and the surface of the lens body 4 away from the eyeball surface is the outer surface 1. The average thickness of the lens body 4 (ie the vertical distance between the outer surface 1 and the inner surface 2 ) is 1 mm. The inner surface 2 coincides with the curved surface of the eyeball, and the curvature difference between the inner surface 2 and the curved surface of the eyeball is 1 nm to 1 mm.

[0038] A reflective layer 3 with a thickness of 2000nm~3000nm is arranged in the middle of the lens body 4 between the outer surface 1 and the inner surface 2. The reflective layer 3 is a reflective sheet that can reflect electromagnetic waves with a wavelength of 100~2500nm. The refraction of the reflective layer 3 The rate is 0.9.

Abstract

The invention belongs to the technical field of ophthalmologic lenses, and discloses a moisturizing anti-radiation contact lens. The method solves the problems of dehydration dryness and use state deterioration eyes wearing contact lenses or cosmetic lenses due to electromagnetic radiation damage and temperature rise caused by electromagnetic radiation in the prior art. The moisturizing anti-radiation lens includes an inner surface, an outer surface and a lens body, and the inner surface and / or the outer surface and / or the lens body is (or are respectively) provided with a light reflecting layer, the light reflecting layer is arranged along the curved surface of the lens body, and the light reflecting layer partially or completely covers the inner surface or the outer surface or the lens body. The arrangement of the light reflecting layer reduces the radiation intensity of the inner surface of a reflection zone, reduces the energy absorption of the lens body and the surfaces of eyeballs, especially reduces the heat absorption in order to reduce the temperature of each of the eyeballs and the lens body, so water evaporation prevention and wet lens and eye keeping are realized, and the radiation of electromagnetic waves to the eyes is reduced.

Description

technical field [0001] The invention relates to the technical field of ophthalmic lenses, in particular to a moisturizing radiation-proof contact lens. Background technique [0002] A contact lens, or contact lens, is a lens that is worn on the cornea of ​​the eye. Contact lenses in the narrow sense are used to correct vision or protect the eyes, and colored lenses in the narrow sense can increase the aesthetic feeling. At present, the functions of contact lenses and color contact lenses have been basically integrated. Contact lenses and color lenses include hard and soft lenses, which not only greatly improve the appearance and convenience of patients with refractive errors such as myopia, hyperopia, and astigmatism, but also have a wide field of vision and realistic vision. It also plays a special role in the development of myopia and astigmatism in young people, and in the treatment of special eye diseases. In addition, it can also increase the beauty of the eyes throug...
