摘要

Objective

The current investigation represents to examine the numerous variables that influence tear film interactions alongside the seriousness regarding dry eye through adolescents and young adults, concentrating particularly regarding the implications of broadened Visual Display Terminal (VDT) usage, sleep deprivation, and the surrounding atmosphere. The inspection encompasses essential variables which include Schirmer’s Test 1 (ST1), Tear Film Breakup Time (TBUT), ocular surface staining (OSS), tear osmolarity, blink rate, alongside symptom severity measured by the Ocular Surface Disease Index (OSDI).

Methods

Fifty participants (100 eyes; 33 males, 17 females), aged 18–25 years, were evaluated during morning and nocturnal phases following 5 h of VDT exposure. The purpose inspections comprised ST1, TBUT, OSS, tear osmolarity, alongside blink rate. The previously Ocular Surface Disease Index (OSDI) has been utilised for assessing unreliable warning signs. The statistical evaluations have been performed by employing paired t-tests, Pearson correlation, alongside straight-line regression mathematical modelling.

Results

ST1 values decreased significantly at night (right eye: 18.06 ± 2.49 mm; left eye: 19.02 ± 2.48 mm) compared to morning (right eye: 22.18 ± 1.95 mm; left eye: 23.70 ± 1.94 mm) (p < 0.0001). TBUT declined from 7.2 ± 1.3 to 4.8 ± 1.6 s, accompanied by a 44% reduction in blink rate. OSDI scores rose from 25.4 ± 6.2 to 42.8 ± 7.9, correlating negatively with TBUT (r = -0.69, p < 0.01). Tear osmolarity demonstrated rising levels through ailments associated with lack of moisture alongside elevated the monitor luminescence. Significant correlations have been determined between ST1, TBUT, osmolarity, alongside OSS.

Conclusion

Prolonged exposure to visual display terminals (VDT) alongside inadequate sleep considerably disrupt the tear film alongside intensify the signs of dry eye. Gender-related distinctions alongside the surrounding environment, moreover influences tear dynamics. The outcomes indicate an imperative of preventative screening, ergonomic interventions, along with customised techniques for management to reduce digital eye strain while maintaining ocular surface health in communities at high risk for injury.
