Abstract
Official abstract text for this publication.
The spectacle lens includes a coating film containing tungsten oxide particles, tin oxide particles, and silver particles on a surface of a lens substrate.
First claim
Opening claim text (preview).
What is claimed is: 1. A spectacle lens, comprising a coating film containing tungsten oxide particles, tin oxide particles, and silver particles on a surface of a lens substrate, wherein all of the tungsten oxide particles, the tin oxide particles, and the silver particles are particles having a particle size smaller than a film thickness of the coating film. 2. The spectacle lens according to claim 1 , wherein the coating film has a film thickness of 3 nm or more and 30 nm or less. 3. The spectacle lens according to claim 1 , wherein the coating film further contains molybdenum. 4. The spectacle lens according to claim 1 , wherein the spectacle lens has an antireflective film below the coating film. 5. The spectacle lens according to claim 1 , wherein all of the tungsten oxide particles, the tin oxide particles, and the silver particles have a particle size of 2 nm or more and 5 nm or less. 6. The spectacle lens according to claim 1 , wherein the coating film contains a binder component containing silicon oxide as a main component. 7. A spectacle lens, comprising a coating film containing tungsten oxide particles, tin oxide particles, and silver particles on a surface of a lens substrate, wherein all of the tungsten oxide particles, the tin oxide particles, and the silver particles have a particle size of 2 nm or more and 5 nm or less. 8. The spectacle lens according to claim 7 , wherein the coating film further contains molybdenum. 9. The spectacle lens according to claim 7 , wherein the spectacle lens has an antireflective film below the coating film. 10. A spectacle lens, comprising a coating film containing tungsten oxide particles, tin oxide particles, and silver particles on a surface of a lens substrate, wherein the coating film contains a binder component containing silicon oxide as a main component. 11. The spectacle lens according to claim 10 , wherein the coating film further contains molybdenum. 12. The spectacle lens according to claim 10 , wherein the spectacle lens has an antireflective film below the coating film.
