FIELD: physics.
SUBSTANCE: optical and/or technical screen with a concave form of the curvature radius, is made such that one or more of its surfaces visible to an observer has a concave form with curvature radius R more than twice greater than distance from the screen L to the observer and not more than double the distance to the nearest source, the glare of which needs to be eliminated.
EFFECT: reduction or attenuation of glares from the screen which can be seen by an observer.
