In the work an there is given an assessment of the working conditions during intense visual activity without the use of displays medium and optical devices. It is proved that the indices of evaluation of the light environment in accordance with "Guidelines for hygienic assessment of factors working environment and labor process" P 2.2.2006-05 R 2.2.2006-05 were substantiated to be been supplemented by indices of uneven brightness and color temperature of the light source. It is confirmed that the intense visual work is a meaningful evaluation of the constraint, especially in terms of sensory loads. In the dynamics of the working day there was revealed the deterioration of the visual analyzer and psychoemotional state. In periodic medical examinations there was noted a marked gain in revealed pathology of diseases of the eye and adnexa with increasing work experience. A method for estimation of the risk in people doing intense visual work, taking into account the evaluation of the light environment, intensity of work, dynamics of the functional state during the shift has been proposed.
