## 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

### Claim 1

A goggle lens comprising
a lens body and
a protective film;
wherein the lens body includes a first surface, and a second surface opposite to the first surface; and
wherein the protective film has multiple layers including 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 stacked in turn; the protective film is connected to either the first surface or the second surface by the silica composite film layer.

### Claim 2 (depends on 1)

The device as claimed in claim 1, wherein the silica composite film layer is produced by a mixture of silicon monoxide and silicon dioxide.

### Claim 3 (depends on 2)

The device as claimed in claim 2, wherein the second zirconium dioxide film layer is able to be replaced by titanium pentoxide (Ti3O5).

### Claim 4 (depends on 3)

The device as claimed in claim 3, 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.

### Claim 5 (depends on 1)

The device as claimed in claim 1, wherein the second zirconium dioxide film layer is able to be replaced by titanium pentoxide (Ti3O5).

### Claim 6 (depends on 5)

The device as claimed in claim 5, 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.

### Claim 7 (depends on 2)

The device as claimed in claim 2, 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.

### Claim 8 (depends on 1)

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.
