<b>Aim</b>: to evaluate the frequency and severity of subjective conjunctival signs of computer vision syndrome (CVS) and to discuss their possible causes and mechanisms.
</p>
<p>
<b>Patients and Methods:</b> online screening of 367 students from different Russian universities, including 303 (82.5%) girls and 64 (17.5%) boys, aged 15–30 years (20.6±0.1 years), was conducted using a multidimensional author's questionnaire and validated scales for assessing Internet addiction and daily duration and experience of using digital devices (DDs).
</p>
<p>
<b>Results</b>: analysis of the screening data showed that only 10.3% of the respondents had no complaints of conjunctival signs of CVS. Predominant conjunctival symptoms (both in terms of frequency and severity) were dryness, redness and tearing. The structure of "always" and "very often" complaints of eye dryness (4.6% and 8.5% respectively), eye redness (3.3% and 7.0% respectively) and tearing (2.7% and 5.5% respectively) is similar. The structure of "very often" complaints differs from the structure of "always" complaints in that burning and itching (19.5%) ranks third after dryness (21.3%) and redness (20.4%). Eye dryness (5.2%), redness (4.0%) and tearing (2.7%) were the most common "very severe" complaints. Eye redness (10.3%), eye dryness (9.4%), and burning and itching (7.3%) were most common among "severe" complaints.
</p>
<p>
<b>Conclusion</b>: the authors' findings and published data show that the high rate of complaints of visual discomfort with conjunctival signs and disorders of the lacrimal apparatus when using DDs is not only due to the effect of reduced blink rate and increased evaporation of the tear film, but also to much more complex, systemic neuro-ophthalmological mechanisms. The most likely mechanism is vegetative dysregulation resulting from excessive and prolonged use of information technologies and DDs, and ignorance of hygienic and ergonomic standards.
