Abstract
A lightweight light screen (1) that emits a low-intensity, diffused light of uniform brightness from its interior surface. The light screen covers both of a user's (2) eyes (3) when wom, thereby preventing ambient light from entering the user's eyes. The wearer of the light screen can see only the emitted light. The nature of the emitted light in combination with isolation from ambient visual stimuli provide a restful and therapeutic environment for the wearer. The light screen has two apertures (11) with shades (14, 15) that can be used uncover the apertures. The apertures are positioned with respect to each eye such that when uncovered the wearer can read or perform other short-focal-distance tasks that require eyesight while obtaining benefits from the emitted light. The combined area of the apertures is less than 5% of the light emitting area of the light screen so the user can maintain his/her sense of isolation while performing tasks and continue to derive benefit from irradiation.
