Abstract
A light-altering filter for use by military and law-enforcement personnel in lowlight environments is disclosed. The filter can be placed between a lit computer monitor screen and the face of the computer user. Light coming from the monitor screen is modified by the filter so that the night vision capabilities of the computer user are not adversely affected, and splash-back reflective illumination of the user is minimized.
