方法：收集2013-10/12印度南部金奈地区三个IT公司员工进行地横断面调查。入选标准：从事IT行业至少6mo以上，年龄≥18岁，自愿参与研究并签署知情同意书。通过问卷调查和眼科检查收集相关信息，包括社会人口特征。采用Schirmer's试验进行干眼评估，所有结果应用SPSS 16.0统计软件进行分析。

结果：大约有五分之一的参与者(n=36，18%)疑患有干眼，平均年龄29岁(SD=7)，并且大多数是男性，本科生/研究生，单身，住在城市的大家庭中。多风的环境显著地增加了红眼的患病率(P=0.04)及眼睛的灼热感(P=0.000)。看电视同样也能增加了眼睛的异物感(P=0.01)，从而导致分泌物过多(P=0.02)。

结论：研究结果显示，许多日常活动比如看电视，使用电脑，读书，吹空调及多风的环境(干燥的环境)等都与干眼的症状相关。而且看电视及多风的环境更能加重干眼的一些症状。这项研究强调IT人群迫切需要多种方法和措施减轻干眼症。

METHODS: This was a pilot cross-sectional study conducted for a period of 3mo from October-December, 2013 in Chennai, South India. The study population was enrolled from three IT companies in a city in Chennai. The inclusion criteria consisted of individuals working in the IT industry at least for a period of 6mo, aged 18y or above and giving voluntary, written informed consent. Variable information was gathered by using series of questionnaires and ophthalmic assessment. Information about sociodemographic characteristics was also gathered. Schirmer's test was performed for ophthalmic assessment. All of the analysis was performed by using SPSS vs.16.

RESULTS: About one fifth(n=36, 18%)of the participants were suspected to have dry eyes, with mean age of 29y(SD=7), and majority of them being males, graduates/ postgraduates, single, living in extended families in urban areas. Windy environment significantly showed to aggravate redness(P=0.04)and burning sensation of the eyes(P=0.000). Similarly, watching television significantly showed to aggravate gritty sensation(P=0.01)and led to excess mucous in the eyes(P=0.02).

CONCLUSION:Based on the results of our study, it can be concluded that the exposure to various daily activities such as watching television, using computer, reading, and use of air conditioning and windy environments(dry environments)were associated with signs and symptoms of dry eyes. Also, watching television and windy environment were significantly positively correlated with some of the signs of dry eye. This study emphasizes the urgent need of multi-factorial approach including policy measures for addressing the burden of dry eye in population.
