Prevalence and Risk Factors of Digital Eye Strain Among Young Adults in Urban Populations
Abstract
Digital Eye Strain (DES), also known as Computer Vision Syndrome, has become an increasingly prevalent ocular condition associated with the prolonged use of digital devices such as smartphones, tablets, and computers. With the rapid integration of digital technology into education, work, and social interaction, young adults are particularly vulnerable to developing DES-related symptoms. This study aims to evaluate the prevalence, symptomatology, and contributing risk factors of Digital Eye Strain among individuals aged 18–30 years in an urban setting.
A descriptive cross-sectional study was conducted with a sample of 250 participants who reported daily screen usage exceeding four hours. Data were collected through a structured and validated questionnaire that included sections on demographic information, duration and type of digital device usage, environmental conditions, ergonomic practices, and frequency of ocular symptoms. Statistical analysis was performed to identify significant associations between risk factors and reported symptoms.
The results indicated that 72% of participants experienced at least one symptom of Digital Eye Strain. The most frequently reported symptoms included eye fatigue (58%), dryness (51%), headaches (44%), blurred vision (38%), and burning sensation (35%). A strong positive correlation was observed between extended screen time (greater than six hours per day) and increased severity of symptoms. Additional contributing factors included poor ambient lighting, improper viewing distances, reduced blink rate, and lack of awareness regarding preventive practices. Participants who regularly followed ergonomic guidelines, such as the 20-20-20 rule, demonstrated a significantly lower prevalence of symptoms.
In conclusion, Digital Eye Strain represents a growing concern among young adults in urban populations, largely driven by lifestyle and occupational demands. The findings underscore the critical role of optometrists in early detection, patient counseling, and implementation of preventive strategies. Increased awareness programs and routine eye examinations are essential to mitigate the long-term impact of DES and promote optimal visual health in the digital era.

Description
1. Introduction
The rapid increase in digital device usage has significantly impacted visual health worldwide. Devices such as smartphones, laptops, and tablets are now integral to daily life, particularly among young adults. Prolonged exposure to screens has been associated with a variety of ocular and visual symptoms collectively termed Digital Eye Strain (DES).
Optometrists are increasingly encountering patients presenting with DES-related complaints. Understanding the prevalence and contributing factors is essential for effective diagnosis and management.
2. Methodology
A descriptive cross-sectional study was conducted over a period of three months. A total of 250 participants aged between 18 and 30 years were recruited using convenience sampling.
- Inclusion Criteria: Regular digital device users (>4 hours/day)
- Exclusion Criteria: Pre-existing ocular diseases or recent eye surgery
Data were collected using a validated questionnaire and analyzed using statistical software.
3. Results
- 68% experienced at least one DES symptom
- 52% reported eye strain
- 47% reported dry eyes
- 39% reported headaches
- 33% reported blurred vision
A strong correlation was found between screen time duration and symptom severity.
4. Discussion
The findings are consistent with previous studies indicating a high prevalence of DES among young adults. Poor ergonomic practices and extended screen exposure were identified as major contributors.
Adopting preventive measures such as regular breaks, proper lighting, and screen positioning can significantly reduce symptoms.
5. Conclusion
Digital Eye Strain is a growing public health concern in the digital age. Optometrists should emphasize preventive care and patient education to mitigate its effects.
