Abstract: An open view facemask visor is an apparatus composed of a high impact resistive material any portion of which is capable of filtering or reflecting light. The visor is formed by shaping a nominally thick sample of the impact resistive material such that the finished product can be affixed either over or under a given helmet facemask design. Once installed, an open view facemask visor enhances the protection of a sporting helmet facemask by providing the user a barrier to light, glare, or debris without obscuring the “open view” to the user's eyes. Whether by integrating a clear section in the tinting of the high impact resistive material or simply providing a physically open, or cut-out, section in the visor, proper positioning of the visor shield on the facemask will not obstruct one's ability to view the helmet wearer's eyes.
