ATTACHABLE OPTICAL ELEMENT ARRANGEMENTS AND METHODS

摘要

Described is a kit, an optical insert assembly and a method for attaching an optical insert to a viewing lens of an eye-shielding device. The kit includes an optical insert with an outer perimeter, and a flexible border attachment element with an inner periphery area extending inward of the outer perimeter of the optical insert, and an outer periphery area extending outward of the outer perimeter of the optical insert, and having a first adhesive area for attachment to the optical insert and a second adhesive area for attachment to the viewing lens. When attached, the border attachment element defines a buffer zone spanning the inner periphery and outer periphery areas. The optical insert assembly includes the elements of the kits described herein, attached to a viewing lens of an eye-shielding device.

1. A kit for attaching an optical insert to a viewing lens of an eye-shielding device, the kit comprising:
an optical insert having an outer perimeter; and a flexible border attachment element having an inner and an outer periphery and comprising a first adhesive area for attachment to the optical insert and a second adhesive area for attachment to the viewing lens, characterized in that at least a portion of the inner periphery of the flexible border attachment element extends inward of the outer perimeter of the optical insert defining an inner periphery area, and at least a portion of the outer periphery of the flexible border attachment element extends outward of the outer perimeter of the optical insert defining an outer periphery area, thereby defining a buffer zone spanning the inner and outer periphery areas wherein the buffer zone covers an area of the viewing lens.
