Adhesive mountable stack of removable layers
First Claim
1. 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 configured to protect the wearer from projectiles, the 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 about 0.2 of the lens refractive index;
removing a protective liner from a bottom surface of the lens stack to expose an optically clear dry mount adhesive layer, anddry 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 about 0.2 of the lens refractive index and each removable layer refractive index.

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.
