FIELD: medicine, ophthalmology.
SUBSTANCE: the present innovation deals with testing characteristics of operator's visual analyzer in Navy, aviation, interplanetary navigation and ground-based controls stations. The suggested measuring device contains a trial rim and stimulus bearer as test frameworks of projection block designed with possibility to present test frameworks both with transparent background and paper-depicted ones. A trial rim contains fixed polarizer and rotating analyzer with fixed turning lever and logarithmic scale.
EFFECT: higher efficiency of evaluation at operator's working place.
