Abstract
Official abstract text for this publication.
The disclosure includes producing a plastic lens with an antireflection film at a lower cost. The plastic lens is configured to include a plastic base material; and an antireflection film having an electrically conductive layer that is formed in contact with a surface of the plastic base material and that has colorless transparency, and an antireflection film main body that contains a metal oxide, formed on the electrically conductive layer.
First claim
Opening claim text (preview).
The invention claimed is: 1. A plastic lens, comprising: a plastic base material; and an antireflection film having an electrically conductive layer that is deposited on a surface of the plastic base material and that has colorless transparency, and an antireflection film main body that contains a metal oxide, formed on the electrically conductive layer. 2. The plastic lens according to claim 1 , wherein the electrically conductive layer contains an oxide of at least one element among indium, tin, zinc and titanium. 3. The plastic lens according to claim 1 , wherein the plastic base material is formed of any of materials of allyl resin, urethane resin, polysulfide resin and polycarbonate resin. 4. The plastic lens according to claim 2 , wherein the plastic base material is formed of any of materials of allyl resin, urethane resin, polysulfide resin and polycarbonate resin. 5. The plastic lens according to claim 1 , wherein the antireflection film main body is formed in contact with the electrically conductive layer. 6. The plastic lens according to claim 1 , wherein the electrically conductive layer is formed of inorganic material. 7. A plastic lens, comprising: a plastic base material; and an antireflection film having an electrically conductive layer that is formed in direct contact with a surface of the plastic base material and that has colorless transparency, and an antireflection film main body that contains a metal oxide, formed on the electrically conductive layer. 8. The plastic lens according to claim 7 , wherein the electrically conductive layer contains an oxide of at least one element among indium, tin, zinc and titanium. 9. The plastic lens according to claim 7 , wherein the plastic base material is formed of any of materials of allyl resin, urethane resin, polysulfide resin and polycarbonate resin. 10. The plastic lens according to claim 8 , wherein the plastic base material is formed of any of materials of allyl resin, urethane resin, polysulfide resin and polycarbonate resin. 11. The plastic lens according to claim 7 , wherein the antireflection film main body is formed in contact with the electrically conductive layer. 12. The plastic lens according to claim 7 , wherein the electrically conductive layer is formed of inorganic material.
