ABSTRACT:
The present invention relates to a protective cover system. One embodiment of the present invention relates to a multi-layer protective cover system configured to be disposed over a transparent object. Particular embodiments relate to incorporating the system with electronic devices and articles of eyewear that include transparent objects such as display screens and lenses respectively. Each layer of the system includes a transparent member, an adhesion system, and a removal system. The transparent member is shaped to two dimensionally conform or exceed the dimensions of an exposed outer surface of the transparent object. The adhesion system removably couples the transparent member to the transparent object in a manner that does not significantly affect the transparency of the combination. The removal system allows individual layers to be removed without substantially affecting the remaining layers or the transparency of the system. One particular removal system embodiment includes attaching an outer tab to each of the layers. Each tab may be uniquely positioned along the outer edge of each layer to allow a user to peel away one or more top layers without affecting the layers below. In addition, each tab may be uniquely colored and/or numerically labeled to indicate the sequence of layers. A second embodiment of the invention relates to a method for sequentially removing protective layers from a transparent object as each layer becomes damaged or otherwise less transparent.
