Abstract
A protective lens is provided having a first layer, a second layer and a third layer. The first, second and third layers each comprises a first surface and a second surface. The first layer comprises a substantially non-reactive material. The first surface of the second layer is positioned adjacent to the second surface of the first layer. The second layer comprises a substantially fire resistant material. The first surface of the third layer is positioned adjacent to the second surface of the second layer. The third layer comprises a substantially hydrophobic material.

A protective lens comprising:
- a first layer comprising a first surface and a second surface, the first layer comprising a substantially non-reactive material;
- a second layer comprising a first surface and a second surface, the first surface of the second layer being positioned adjacent to the second surface of the first layer, the second layer further comprising a substantially fire resistant material;
- and
- a third layer comprising a first surface and a second surface, the first surface of the third layer being positioned adjacent to the second surface of the second layer, wherein the third layer comprises a substantially hydrophobic material.
A protective article comprising:
- a garment comprising a first surface and a second surface and defining an aperture having a perimeter;
- and
- a protective lens coupled to the first surface and second surface of the garment about the perimeter of the aperture, the lens comprising:
- a first layer comprising a first surface and a second surface, the first layer comprising a substantially non-reactive material;
- a second layer comprising an first surface and a second surface, the first surface of the second layer being positioned adjacent to the second surface of first layer, the second layer further comprising a substantially fire resistant material;
- and
- a third layer comprising a first surface and a second surface, the first surface of the third layer being positioned adjacent to the second surface of the second layer, wherein the third layer comprises a substantially hydrophobic material.
A method of constructing a protective article, the method comprising:
- providing a first layer having a first surface and a second surface and comprising a substantially non-reactive material, a second layer having a first surface and a second surface and comprising a substantially fire resistant material, and a third layer having a first surface and a second surface and comprising a substantially hydrophobic material;
- positioning the first surface of the second layer adjacent to the second surface of the first layer;
- positioning the first surface of the third layer adjacent to the second surface of the second layer;
- providing a garment having an aperture, the aperture defining a perimeter;
- and
- coupling the first, second and third layers together and to the garment about the perimeter of the garment.
