Abstract
Abstract A magnifying attachment for use on push buttons such as those on a more modern telephone and having an image magnifying element to magnify indicia imprinted or otherwise located on a button. The attachment has a depending skirt with the magnifying element secured thereto with the skirt being sized and shaped to receive the upper end of the button therein in frictional engagement for securing the magnifying element in overlying relation to the end surface of the button. The attachment also includes an upwardly extending peripheral rib to provide protection for the magnifying element and prevent an operator's finger from slipping from the attachment and contacting an adjacent button.
