Abstract
A collapsible-light shield for a portable computer shields direct and indirect light from the computer display and from the eyes of the user. The light shield has four flexible panels that form a tubular shape when in use. One end of the light shield has a contoured viewing port through which the user may view the screen. The other end of the light shield has a ring-like elastic fastener that detachably secures to three sides of the computer display. Each panel has two bisecting fold lines about which the tubular light shield may be collapsed into a substantially flat profile that is a small fraction of its original size.
