Background: Dry Eye Syndrome (DES) is a prevalent yet underrecognized ocular condition marked by insufficient tear production or poor tear quality, causing discomfort and visual disturbances. Despite its increasing incidence, public awareness remains limited, contributing to delayed diagnosis and inappropriate management. This study assessed DES-related knowledge, awareness and misconceptions among residents of Himachal Pradesh, India and explored demographic factors influencing awareness levels. Materials and Methods: A descriptive cross-sectional study was conducted among 400 adults across Himachal Pradesh from October to December 2024. Data were collected via a structured questionnaire covering socio-demographics, DES knowledge and healthcare-seeking behavior. Responses were categorized into four knowledge levels: Very Good (≥80%), Good (60%-79%), Fair (41%-59%) and Poor (<40%). Statistical analysis identified associations between demographics and knowledge scores. Results: Participants exhibited fair overall awareness, with 38.5% achieving "Very Good" knowledge and 39.0% scoring "Good." While 81.5% correctly identified DES as a tear deficiency disorder and 86.8% recognized its chronic nature, misconceptions were common. Only 66.5% identified a gritty eye sensation as a symptom and 65.8% linked low humidity to symptom worsening. Awareness gaps were more prominent in rural populations (59% of participants) and those with lower education levels. Conclusion: Despite satisfactory overall awareness, significant gaps persist in recognizing symptoms, preventive measures and complications of DES. Targeted educational interventions and improved rural healthcare outreach are crucial to enhancing public understanding, promoting timely care and reducing preventable ocular complications.
Dry eye disease (DED), commonly referred to as "dry eyes," is a prevalent yet frequently underestimated ocular disorder characterized by insufficient tear production or poor tear quality, resulting in symptoms such as irritation, discomfort, redness, visual disturbances and potentially reduced quality of life [1,2]. Despite its widespread occurrence and significant impact on daily activities and productivity, public awareness about dry eye remains inadequate, often overshadowed by more conspicuous ocular conditions. Misconceptions regarding its causes, symptoms and effective management frequently delay diagnosis, encourage inappropriate self-treatment and consequently increase the likelihood of chronic complications [3-5].
In India, the prevalence of dry eye disease is rising, driven by factors such as increased screen time, aging populations, environmental pollution and lifestyle habits. Rural regions and communities with limited access to ophthalmic care face particular challenges, often experiencing delayed recognition of symptoms and suboptimal treatment outcomes. Himachal Pradesh, a northern Indian state marked by rugged mountainous terrain, dispersed rural settlements and varying degrees of healthcare infrastructure, exemplifies the complexities associated with managing dry eye conditions effectively. Limited awareness and prevalent misconceptions regarding dry eye, including confusion over its relationship to vision-threatening conditions and reliance on ineffective home remedies, further complicate its management in these settings [6-8].
While effective treatments for dry eye are widely available, ranging from simple lubricants to advanced therapeutic options, a significant barrier remains the public’s insufficient understanding and widespread misconceptions about the disease. Studies elsewhere have shown a strong correlation between enhanced public awareness and improved disease management, better compliance with treatment and reduced ocular morbidity [7,8]. However, systematic evaluations of public knowledge, awareness and misconceptions specifically regarding dry eye syndrome in regions like Himachal Pradesh remain scarce.
Therefore, this study aims to thoroughly assess public awareness, common perceptions and prevalent misconceptions about dry eye syndrome among residents of Himachal Pradesh. By identifying socio-demographic determinants associated with varying awareness levels, the study will provide critical insights that inform targeted, culturally appropriate educational interventions and public health strategies. Ultimately, improving community-level understanding of dry eye disease is essential for promoting timely diagnosis, effective management and enhancing overall ocular health and quality of life in this geographically challenging region.

The current study comprehensively evaluated public awareness, understanding and misconceptions regarding Dry Eye Syndrome (DES) among the general population of Himachal Pradesh, offering valuable insights into critical knowledge gaps that can significantly affect ocular health outcomes. Participants generally displayed commendable foundational awareness, accurately identifying DES as a condition caused by inadequate tear production or poor tear quality and recognizing its chronic nature and potential impact on vision. Despite these positive findings, important misconceptions and inadequate knowledge persist, particularly concerning preventive measures, specific symptoms, risk factors and possible complications associated with untreated dry eyes. Such misunderstandings may hinder timely diagnosis and appropriate treatment, potentially leading to unnecessary discomfort and long-term ocular morbidity.
Analysis of socio-demographic characteristics revealed balanced gender participation, active engagement among working-age adults (particularly those aged 26-45 years) and significant representation from rural communities (59.0%). Rural populations, characterized by limited access to ophthalmological services, healthcare infrastructure constraints and generally lower health literacy, emerged as particularly vulnerable to misinformation and inadequate preventive practices. These communities frequently face barriers related to geographical isolation and limited ophthalmic resources, thus relying heavily on traditional remedies or self-management practices that may exacerbate symptoms. Consequently, targeted educational interventions must specifically address rural populations, utilizing culturally sensitive, accessible materials and leveraging local community health resources such as Accredited Social Health Activists (ASHAs) or Anganwadi workers for effective communication and improved health literacy.
While the majority of respondents demonstrated adequate baseline knowledge, notable gaps remained, especially in recognizing subtle or less well-known symptoms, such as a gritty sensation, visual fatigue and environmental factors exacerbating symptoms, such as low humidity. Additionally, a substantial proportion lacked clarity about nutritional factors such as omega-3 fatty acids' role in tear production and ocular health, potentially limiting proactive dietary interventions. Furthermore, misconceptions regarding the relationship between aging, medications and dry eyes were prevalent. Misunderstandings about these underlying causes might contribute significantly to ineffective preventive strategies and delayed healthcare seeking, particularly among vulnerable or elderly groups.
Importantly, while participants generally recognized the symptomatic manifestations of dry eyes-such as burning sensations and eye fatigue-they demonstrated notable uncertainty concerning potential serious complications like corneal irritation and compromised visual acuity resulting from untreated conditions. This gap is significant, as delayed recognition of complications can result in prolonged discomfort, impaired vision, or permanent ocular damage. Additionally, there was substantial confusion regarding preventive measures, with a considerable segment unaware of the protective benefits associated with lifestyle modifications like reduced screen exposure, increased humidity, regular breaks during prolonged visual tasks and adequate hydration [9-11].
The categorization of participants’ knowledge scores highlighted both strengths and areas requiring urgent educational intervention. Although the majority demonstrated either "Good" (39.0%) or "Very Good" (38.5%) knowledge, a significant minority fell into "Fair" (16.8%) or "Poor" (5.8%) knowledge categories. These lower knowledge levels correlated strongly with socio-demographic variables such as rural residency and lower educational attainment, reinforcing the link between limited healthcare access, lower education levels and reduced ocular health literacy. Therefore, public health initiatives must prioritize these high-risk demographic groups, implementing targeted, accessible and culturally relevant educational campaigns that clearly communicate essential aspects of DES, preventive measures, early symptom recognition and the importance of seeking timely medical care.
In conclusion, despite generally sound foundational knowledge regarding Dry Eye Syndrome among residents of Himachal Pradesh, notable misconceptions and knowledge gaps persist, especially within rural, elderly and less educated segments of the population. Addressing these deficiencies through comprehensive public education campaigns, bolstering rural healthcare infrastructure and emphasizing consistent, clear and culturally appropriate messaging is crucial for reducing the prevalence, severity and complications of dry eyes. Future research should assess the impact of these interventions longitudinally, monitoring sustained improvements in public knowledge, behavioral practices, healthcare-seeking behaviors and overall ocular health outcomes in the region.
