Goggle lens

Abstract

A goggle lens is revealed. The goggle lens includes a first surface, a second surface opposite to the first surface, and a protective film connected to either the first surface or the second surface. The protective layer is a multi-layer structure formed by a silica composite film layer, a first zirconium dioxide film layer, a first silica film layer, an indium tin oxide (ITO) film layer, a second zirconium dioxide film layer and a second silica film layer in turn. Thereby harmful light such as blue light, infrared light, etc. is blocked by the protective film and ultraviolet light is also absorbed by the protective film for protecting user's eyes from damages.

Claims

8. The device as claimed in claim 1, wherein the protective film further includes at least one second zirconium dioxide film layer and at least one second silica film layer arranged over the second silica film layer in turn; thus the number of layers in the protective film is increased.

Description

BRIEF DESCRIPTION OF THE DRAWINGS

(1) The structure and the technical means adopted by the present invention to achieve the above and other objects can be best understood by referring to the following detailed description of the preferred embodiments and the accompanying drawings, wherein:

(2) FIG. 1 is a partial enlarged view of an embodiment according to the present invention;

(3) FIG. 2 is a schematic drawing showing an embodiment assembled on a pair of glasses according to the present invention;

(4) FIG. 3 is a partial enlarged view of another embodiment according to the present invention;

(5) FIG. 4 is a partial enlarged view of a further embodiment according to the present invention.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

(6) A goggle lens of the present invention mainly includes a lens body 1 and a protective film 2. The lens body 1 can be a flat lens, or an optical lens that corrects near-sighted or far-sighted. The lens body 1 consists of a first surface 11 and a second surface 12 opposite to the first surface 11.

(7) The protective film 2 is connected to either the first surface 11 or the second surface 12 of the lens body 1. The protective film 2 is a multi-layer structure formed by a silica composite film layer 21, a first zirconium dioxide film layer 22, a first silica film layer 23, an indium tin oxide (ITO) film layer 24, a second zirconium dioxide film layer 25 and a second silica film layer 26 stacked in turn. The protective film 2 is connected to the first surface 11 by the silica composite film layer 21. The silica composite film layer 21 is produced by a mixture of silicon monoxide and silicon dioxide.

(8) Refer to FIG. 2, the lens B of the present invention not only blocks blue light and infrared light but also absorbs harmful light such as ultraviolet light through the multi-layer protective film 2 disposed on the first surface 11 of the lens body 1. When users wear glasses A disposed with the lenses B of the present invention, the lenses B of the present invention protect users' eyes from damages resulted from harmful light such as blue light, infrared light, ultraviolet light, etc.

(9) Refer to FIG. 3, another embodiment is revealed. In this embodiment, the protective film 2 is connected to the second surface 12 of the lens body 1 by the silica composite film layer 21.

(10) Refer to FIG. 4, a further embodiment is revealed. In this embodiment, the protective film 2 further includes a second zirconium dioxide film layer 25 and a second silica film layer 26 arranged over the original second silica film layer 26 in turn. The number of layers in the protective film 2 is increased. Moreover, a combination of a second zirconium dioxide film layer 25 and a second silica film layer 26 can be arranged over the original second silica film layer 26 repetitively.

(11) The second zirconium dioxide film layer 25 can be replaced by titanium pentoxide (Ti3O5) film (not shown in figure).

(12) Additional advantages and modifications will readily occur to those skilled in the art. Therefore, the invention in its broader aspects is not limited to the specific details, and representative devices shown and described herein. Accordingly, various modifications may be made without departing from the spirit or scope of the general inventive concept as defined by the appended claims and their equivalents.
