Abstract:
1. An anti-fog gauge lens, for use with a gauge lens, comprising: a substantially planar transparent lens substrate having an outer surface and an inner surface, wherein the outer surface includes a sidewall extending annularly from the lens substrate; a single-layer film having a first surface which is adjacent to and substantially covering and bonded to said inner surface during the molding process of said lens by pre-heating a mold to a molding temperature prior to the molding process and heating a mold in which the single layer film is placed during the molding process; and an intermolded bond formed between the single-layer film and the inner surface of the substantially planar transparent lens during the molding process, wherein a second surface having hydrophilic properties preventing moisture condensation from forming, wherein the lens is configured to engage a gauge body that is part of the gauge and the lens includes a tab in the sidewall that engages a slot in the gauge body.
