Abstract

A spectacle optical article and a technology related thereto, the spectacle optical article including an outer surface that is a surface on the object side and an inner surface that is a surface on the eyeball side, and containing glossy particles with particle diameters of 50 to 150 μm between both the surfaces.

First claim

1 . A spectacle optical article comprising an outer surface that is a surface on an object side and an inner surface that is a surface on an eyeball side, the spectacle optical article containing glossy particles with particle diameters of 50 to 150 μm between the outer surface and the inner surface.

2 . The spectacle optical article according to claim 1 , further comprising a glossy particle-containing layer in which the glossy particles are accommodated in a layer having a thickness 1.5 times a maximum particle diameter of the glossy particles.

3 . The spectacle optical article according to claim 2 , further comprising a cover layer provided to cover the glossy particle-containing layer.

4 . The spectacle optical article according to claim 1 , further comprising a substrate containing the glossy particles.

5 . The spectacle optical article according to claim 1 , further comprising:
a substrate; and an antireflection layer provided so as to cover at least one of an outer surface and an inner surface of the substrate.

6 . The spectacle optical article according to claim 1 , further comprising:
a substrate; a primer layer provided so as to cover at least one of an outer surface and an inner surface of the substrate; and a main layer provided so as to cover the primer layer, wherein a glossy particle-containing layer in which the glossy particles are accommodated in a layer having a thickness of 1.5 times a maximum particle diameter of the glossy particles includes the glossy particles and at least one of the primer layer and the main layer, and a cover layer provided to cover the glossy particle-containing layer includes the main layer.

7 . The spectacle optical article according to claim 6 , wherein the main layer includes at least one of a smoothing layer, a photochromic layer, and a hard coat layer.

8 . The spectacle optical article according to claim 6 , wherein the main layer has a thickness of 20 to 200 μm.

9 . The spectacle optical article according to claim 1 , wherein the glossy particles are at least one of particles of metal or particles of an oxide of the metal, and particles constituting a pearlescent pigment.

10 . The spectacle optical article according to claim 1 , the spectacle optical article being a dyed lens, wherein a mean transmittance of a line-of-sight passing portion is 8% or more.

11 . The spectacle optical article according to claim 1 , the spectacle optical article being a transparent lens, wherein a mean transmittance of a line-of-sight passing portion is 60% or more.

12 . The spectacle optical article according to claim 1 , the spectacle optical article being a spectacle lens, spectacles including the spectacle lens, sunglasses, or goggles.

13 . The spectacle optical article according to claim 1 , wherein the glossy particles are unevenly distributed between the outer surface and the inner surface of the spectacle optical article and in a peripheral portion when the spectacle optical article is viewed from front.

14 . A method for manufacturing a spectacle optical article including an outer surface which is a surface on an object side and an inner surface which is a surface on an eyeball side, the method comprising adding glossy particles having particle diameters of 50 to 150 μm between the outer surface and the inner surface.

15 . The method for manufacturing a spectacle optical article according to claim 14 , the method further comprising applying a glossy particle-containing liquid so as to cover at least one of an outer surface and an inner surface of a substrate.

16 . The method for manufacturing a spectacle optical article according to claim 14 , the method further comprising:
providing a primer layer on a substrate so as to cover at least one of an outer surface and an inner surface of the substrate; sprinkling the glossy particles on the primer layer; and applying a raw material liquid of a main layer so as to cover the glossy particles.
