[Usefulness of selected psychophysical methods in the evaluation of lighting conditions].
The author examined the frequency of blinking and the position of the near point influenced by practicing a work of considerable visual requirements in various conditions of illumination. It was established that a 7-hours work causes an increase in the frequency of blinking in all the examined persons and receding of the near point in 93 p.c. of subjects. Calculated was the coefficient of correlation and the tangent of the inclination angle of the extent of changes of the measured functions from the logarithm of intensity of the illumination on the work stand. The received coefficients of correlation were -0.08 in case of changes of the near point and -0.63 for the changes of blinking frequency; instead the tangent of inclination angle respectively -0.41 and -122.
