| Description | Une lentille de protection oculaire comprend un substrat de lentille, un agencement d'absorption de lumière bleue et un agencement d'amélioration de lentille. L'agencement d'absorption de lumière bleue comprend une ou plusieurs membranes d'absorption de lumière bleue disposées sur une surface du substrat de lentille pour bloquer la lumière bleue pénétrant à travers le substrat de lentille. L'agencement d'amélioration de lentille est pris en sandwich entre l'agencement d'absorption de lumière bleue et le substrat de lentille, l'agencement d'amélioration de lentille comprenant une ou plusieurs membranes de diffusion de lumière pour améliorer une rigidité et une transmission de lumière du substrat de lentille. |
| Abstract | An eye protection lens includes a lens substrate, a blue light absorbing arrangement, and a lens enhancement arrangement. The blue light absorbing arrangement includes one or more blue light absorbing membranes provided on a surface of the lens substrate for blocking blue light penetrating through the lens substrate. The lens enhancement arrangement is sandwiched between the blue light absorbing arrangement and the lens substrate, wherein the lens enhancement arrangement includes one or more light diffusion membranes for enhancing a rigidity and light transmission of the lens substrate. |

| Claim | WHAT IS CLAIMED IS: An eye protection lens, comprising: a lens substrate; a blue light absorbing arrangement which comprises one or more blue light absorbing membranes provided on a surface of said lens substrate for blocking blue light penetrating through said lens substrate; and a lens enhancement arrangement which comprises one or more light diffusion membranes for enhancing a rigidity and light transmission of said lens substrate, wherein said blue light absorbing membranes are alternating with said light diffusion membranes on said surface of said lens substrate. The eye protection lens, as recited in claim 1, wherein said light diffusion membranes are at least one heat resistance membrane, at least one light transmission enhancement membrane, at least one radiation blocking membrane, and at least one ultraviolet light blocking membrane. 3. The eye protection lens, as recited in claim 1, wherein said light diffusion membranes are a hardening membrane, a first SiCfi membrane, a first ZrCfi membrane, a second SiCfi membrane, a second ZrCfi membrane, a ITO membrane, a third Zr0 2 membrane, and a dirt resistance membrane applied on said surface of said lens substrate in sequence. 4. The eye protection lens, as recited in claim 1, wherein said light diffusion membranes are a combination of a hardening membrane, at least a Si0 2 membrane, at least a Zr0 2 membrane, a ITO membrane, and a dirt resistance membrane applied on said surface of said lens substrate. The eye protection lens, as recited in claim 1, wherein at least seven of said blue light absorbing membranes are deposited on said surface of said lens substrate. The eye protection lens, as recited in claim 1, wherein said lens substrate is made of resin mixed with blue light absorbent. The eye protection lens, as recited in claim 6, wherein a weight ratio of said resin and said blue light absorbent in said lens substrate is 1000:3. 8. The eye protection lens, as recited in claim 1, wherein said lens substrate is selected from a group consisting of a long sighted lens, short sighted lens and reading lens. The eye protection lens, as recited in claim 1, wherein said lens enhancement arrangement and said blue light absorbing arrangement are vapor- deposited on said surface of said lens substrate. The eye protection lens, as recited in claim 1, wherein said lens substrate is a yellow tinted lens. A method for manufacturing an eye protection lens, comprising the steps of: (a) making a lens substrate; (b) applying one or more light diffusion membranes on a surface of said lens substrate for enhancing a rigidity and light transmission of said lens substrate; and (c) applying one or more blue light absorbing membranes provided on said surface of said lens substrate for blocking blue light penetrating through said lens substrate, wherein said blue light absorbing membranes are alternating with said light diffusion membranes on said surface of said lens substrate.. The method as recited in claim 11 wherein, in the step (b), said light diffusion membranes are at least one heat resistance membrane, at least one light transmission enhancement membrane, at least one radiation blocking membrane, and at least one ultraviolet light blocking membrane. The method, as recited in claim 11, wherein said light diffusion membranes are a hardening membrane, a first Si0 2 membrane, a first Zr0 2 membrane, a second Si0 2 membrane, a second Zr0 2 membrane, a ITO membrane, a third Zr0 2 membrane, and a dirt resistance membrane applied on said surface of said lens substrate in sequence. The method, as recited in claim 11, wherein said light diffusion membranes and said light diffusion membranes are applied on said surface of said lens substrate by vapor deposition for at least two hours. The method, as recited in claim 11, wherein at least seven of said blue light absorbing membranes are deposited on said surface of said lens substrate. The method as recited in claim 11 wherein, in the step (a) said lens substrate is made of resin mixed with blue light absorbent. The method, as recited in claim 16, wherein a weight ratio of said resin and said blue light absorbent in said lens substrate is 1000:3. 18. The method, as recited in claim 11, wherein said lens substrate is selected from a group consisting of a long sighted lens, short sighted lens and reading lens. The method, as recited in claim 11, wherein there are totally 15 membranes of said light diffusion membranes and said light diffusion membranes being applied on said surface of said lens substrate. The method, as recited in claim 11, wherein said lens substrate is a yellow tinted lens. |
