title: [Ergonomic evaluation of the effectiveness of the use of television and optic magnifiers for reading by the weak-sighted].
abstract: The author analyzes the results of examinations of visual working abilities of 64 poor-sighted children making use of different correction means in reading and compare the data obtained in reading with optic and television amplifiers before and after 15 min reading a text written in standard type. The findings evidence that the work (reading) induced significant functional disorders both in the sensory and motor components of the visual system; in patients with vision acuity of 0.1 or higher vision fatigue was lower if an optic correction means was employed, and in patients with vision acuity below 0.1 diopters the fatigue was lower if a television amplifier was employed. Recommendations on improvement of television devices for reading and employment of various correction means for poor-sighted subjects are given.
