EFFECT OF YOGIC SHUDDHIKRIYA-TRATAK AND TIL TAIL-NASYA IN THE MANAGEMENT OF COMPUTER VISION SYNDROME (DIGITAL EYE STRAIN) IN WORK PROFESSIONALS

Background-Eyes are the most valuable sense organ or Indriya in human body.But, in todays contemprary Era, growing use of computers in home and office brings with in an increase in health risks, especially for eyes. On such eye problem which is currently gaining importance and affecting the performance of people at workplace in computer users is CVS (Computer Vision Syndrome) also called as Digital eye strain.

Objective:This study is aimed to evaluate the effect of trataka kriya i.e Constant Gazing and Nasya(nasal installation ) of Til Tail(sesame oil) in the management of CVS (Computer Vision Syndrome).

Materials and Methods: 20 participants of the age group 18 to 40 years who were working in it sectors i.e a common job profile having utility of computers , laptops more than 6 hours were recruited in the study. The study design was a pre–post experiment. A convenient sampling technique was used to recruit the participants. The study included participants who use laptops or smartphones for a minimum of 6 hours daily having eye strain, dry eyes, burning sensation in the eyes, headache, and eye fatigue. They were asked to perform trataka kriya once a day for 5 days a week along with installation of til tail oil nasya in both the nostril(4 drops in each nostrils i.e ½ ml) twice a day for consecutive 60 days i.e 2 months.

Results: Results were evaluated by a computer vision syndrome questionnaire and schimer test to assess the visual fatigue experienced by the study participants and also to find out whether the eye produces enough tears to keep it moist. Statistical Analysis and Results Statistical analysis was done using SPSS version 16.0.

Conclusion: The study concluded that there was a significant improvement seen in the signs and symptoms of the students with Digital Eye Strain improvement in discomfort in the participants with digital eye strain.

背景：眼睛是人体最宝贵的感觉器官，亦是梵语语境中的“感官（Indriya）”。在当代社会，家庭与办公场景中计算机的普及程度日益提升，随之而来的是各类健康风险的攀升，眼部健康首当其冲。其中，当前受关注度不断提升、且严重影响计算机使用者职场表现的眼部问题为计算机视觉综合征（Computer Vision Syndrome，CVS），亦称数码视疲劳（Digital Eye Strain）。

研究目的：本研究旨在评估特拉克塔凝视法（Trataka Kriya，即持续凝视训练）配合芝麻油（Til Tail，Sesame Oil）鼻疗法（Nasya）对计算机视觉综合征的干预效果。

材料与方法：本研究招募了20名年龄介于18~40岁、在信息技术行业就职且每日使用电脑、笔记本电脑时长超过6小时的受试者。研究设计为前后对照实验，采用便利抽样法招募受试者。本研究纳入标准为：每日使用笔记本电脑或智能手机时长不少于6小时，且存在眼疲劳、眼干、眼部灼热感、头痛及眼酸胀等症状的人群。受试者需每日进行1次特拉克塔凝视训练，每周训练5天，同时每日两次向双侧鼻腔滴入芝麻油鼻疗液（每侧鼻孔4滴，即0.5毫升），持续干预60天，即2个月。

结果：本研究采用计算机视觉综合征问卷及席默尔试验（Schirmer Test）评估受试者的视觉疲劳程度，同时通过泪液分泌检测评估眼部湿润状态。统计学分析采用SPSS 16.0版本软件完成。

结论：本研究结果显示，数码视疲劳受试者的各项体征与症状均得到显著改善，眼部不适感明显缓解。
