Abstract
In the modern world, there is an increase in the severity of computer vision syndrome (CVS) when using digital devices. Despite numerous studies of ophthalmic symptoms of CVS, neuro-ophthalmic manifestations remain poorly understood. Evaluation of spatial contrast sensitivity (SCS) indicators can be relevant and informative in identifying functional changes in the visual system when using devices. A pilot study was conducted with the participation of 15 healthy people. The subjects were assessed the SCS in the process of habitual activity in a personal device, which was considered a visual load using the author's program «Visocontrastometry» after 15 minutes, 30 minutes, 45 minutes of use. The results were analyzed using descriptive statistics, and the nonparametric Mann – Whitney test was used to test for significance. According to the data obtained, in all time intervals, there is a decrease in SCS at the experimental stage compared with the control indicators of SCS. A statistically significant difference is observed 15 minutes after the visual load at a spatial frequency of 1.0 cycle/deg in the blue color range (p ≤ 0.05). The method for assessing the SCS has shown its adequacy for studying the neuro-ophthalmological aspects of CVS. Keywords: сomputer vision syndrome, contrast sensitivity, device
