Face shield for use with a phoropter

Abstract

A face shield for use with phoropters is described with methods for using the same. The face shield includes a central cavity, which is defined by a front wall and one or more sidewalls extending outwardly from a perimeter of the front wall. The central cavity is configured for surrounding a nasal region, an oral region, and a mental region of an adult person's face. The face shield includes one or more attachment features extending outwardly from the central cavity and configured for attaching the face shield to the phoropter. A method for securing a face shield including attachment features and a central cavity defining an upper cavity region, a middle cavity region, and a lower cavity region to a phoropter is described. The method includes positioning the upper cavity region between lens housings of the phoropter and attaching the attachment features to securing components of the phoropter.
