FIELD: optics.
SUBSTANCE: light conducting optical element, which includes at least one light supplying base, which is equipped with at least two surfaces located parallel to each other; optical means that are used for entering light beams into the base by total internal reflection so that the light would strike one of the above surfaces, set of one or more partially reflecting surfaces located inside of the base, the surfaces of which are not parallel to the above base surfaces; the partially reflecting surfaces being flat surfaces selectively reflecting at an angle, which are crossed by part of beams several times before exiting the base in the required direction.
EFFECT: provision of wide field of view and increase of eye movement area with device fixed.
