The effects of noise on vision efficiency.
The aim of this study was to determine the relationship between intensity, noise duration and non-auditory effect represented by changes both in visual acuity and the near point of accommodation. Changes in vision efficiency determined by a black and white chess board were monitored during and after 1 h exposure to 4 levels of noise: 90 dB-A, 93 dB-A, 96 dB-A or 99 dB-A and 2 h exposure to 96 dB-A. Results indicated that vision impairment can be attributed to a complex relationship between the intensity and the duration of exposure to noise.
