Adhesive mountable stack of removable layers
First Claim
1. An eye protector having a center portion defining a center of gaze of a wearer, the eye protector comprising:
- a lens having a lens refractive index;
an optically clear stack attached to the lens, the stack comprising at least one removable layer, each removable layer having a removable layer refractive index; and
an optically clear dry mount adhesive layer attaching the stack to the lens, the dry mount adhesive layer forming a continuous and uninterrupted adhesive surface over at least the center portion, the dry mount adhesive layer having a dry mount adhesive refractive index, the dry mount adhesive layer being self-wetting and attaching the stack to the lens so that air between the stack and the lens can be removed after the stack is attached to the lens, andwherein the lens refractive index, the dry mount adhesive refractive index, and each removable layer refractive index are matched to within 0.2.

Abstract
An eye protector includes a lens configured to protect the wearer from projectiles, and an optically clear stack attached to the lens. The stack can have one or more removable layers. The eye protector also includes an optically clear dry mount adhesive layer attaching the stack to the lens. The dry mount adhesive may be self-wetting to attach the stack to the lens so that air between the stack and the lens can be removed after the stack is attached and/or adhered to the lens, for example, by applying pressure across the surface of the stack. The refractive indices of the lens, the dry mount adhesive, and each removable layer are matched to within about 0.2.

11. An optically transparent stack for affixing to a lens to form an eye protector, the eye protector having a center portion defining the center of gaze of a wearer, the lens having a lens refractive index, the stack comprising:
-
at least one optically transparent removable layer, each removable layer having a removable layer refractive index; and an optically transparent dry mount adhesive layer applied to a lower surface of the stack for attaching the stack to the lens, the dry mount adhesive layer forming a continuous and uninterrupted adhesive surface, the surface being sized and shaped to cover at least the center portion, the dry mount adhesive layer being self-wetting and capable of attaching the stack to the lens so that air between the stack and the lens can be removed after the stack is attached to the lens, the dry mount adhesive layer having a dry mount adhesive refractive index, wherein the lens refractive index, the dry mount adhesive refractive index, and each removable layer refractive index are matched to within 0.2. - View Dependent Claims (12, 13, 14, 15)

16. A method of protecting an eye protector without significantly reducing visual acuity through the eye protector, the eye protector having a center portion defining a center of gaze of a wearer, the eye protector also having a lens having a lens refractive index, the method comprising:
-
selecting an optically clear stack having at least one removable layer, each removable layer having a removable layer refractive index matched to within 0.2 of the lens refractive index; exposing an optically clear dry mount adhesive layer, and dry mounting the stack to the lens so that the adhesive layer forms a continuous and uninterrupted adhesive layer over at least the center portion, wherein the dry mount adhesive layer is self-wetting and has a dry mount adhesive layer refractive index matched to within 0.2 of the lens refractive index and each removable layer refractive index. - View Dependent Claims (17, 18, 19, 20)
