Methods: 264 participants (132 per group) completed OSDI and CVS-Q; objective measures included TBUT, Schirmer’s test, fluorescein staining, blink rate, and incomplete blink percentage, with outcomes assessed after 4–6 weeks. Results: DES showed longer TBUT, DED had higher fluorescein staining, and overall symptom scores were similar; female sex, greater screen exposure, higher baseline OSDI, and shorter TBUT predicted poorer response. Conclusions: DES and DED overlap yet differ, supporting tailored management targeting tear-film instability and screen-related behaviors.",{"@graph":14,"@context":73},[15,34,56],{"@type":16,"itemListElement":17},"BreadcrumbList",[18,23,27,31],{"item":19,"name":20,"@type":21,"position":22},"https://docshare.wps.com","Home","ListItem",1,{"item":24,"name":25,"@type":21,"position":26},"https://docshare.wps.com/document/","Document",2,{"item":28,"name":29,"@type":21,"position":30},"https://docshare.wps.com/document/healthcare/","Healthcare",3,{"item":32,"name":10,"@type":21,"position":33},"https://docshare.wps.com/document/are-we-treating-the-right-dry-eye-a-comparative-analysis-of-digital-eye-strain-and-traditional-dry-eye-disease-a-prospective-comparative-study/457498/",4,{"url":32,"name":10,"@type":35,"image":36,"author":41,"headline":10,"publisher":44,"fileFormat":47,"inLanguage":8,"description":12,"dateModified":48,"datePublished":49,"encodingFormat":47,"isAccessibleForFree":50,"interactionStatistic":51},"DigitalDocument",{"url":37,"@type":38,"width":39,"height":40},"https://docshare.wps.com/thumbnails/are-we-treating-the-right-dry-eye-a-comparative-analysis-of-digital-eye-strain-and-traditional-dry-eye-disease-a-prospective-comparative-study/457498.png","ImageObject",300,407,{"name":42,"@type":43},"Franzy","Person",{"url":19,"name":45,"@type":46},"DocShare","Organization","application/pdf","2026-11-07","2026-09-30",true,{"@type":52,"interactionType":53,"userInteractionCount":55},"InteractionCounter",{"@type":54},"ViewAction",10,{"@type":57,"mainEntity":58},"FAQPage",[59,65,69],{"name":60,"@type":61,"acceptedAnswer":62},"What clinical aspects were compared between Dry Eye Disease (DED) and Digital Eye Strain (DES)?","Question",{"text":63,"@type":64},"The study compared clinical features including tear-film characteristics and blinking dynamics, along with symptom scores (OSDI and CVS-Q) and treatment outcomes.","Answer",{"name":66,"@type":61,"acceptedAnswer":67},"Which objective findings differed most between the DES and DED groups?",{"text":68,"@type":64},"TBUT was longer in the DES group, while fluorescein staining was higher in the DED group.",{"name":70,"@type":61,"acceptedAnswer":71},"What factors predicted a poorer response to treatment?",{"text":72,"@type":64},"Female sex, greater daily screen exposure, higher baseline OSDI scores, and shorter TBUT were associated with poorer treatment response.","https://schema.org",{"og:url":32,"og:type":75,"og:title":10,"og:site_name":45,"og:description":12},"article",{"robots":77,"canonical":32},"index,follow",{"doc_id":79,"site_id":7},457498,1790820235,{"code":4,"msg":82,"data":83},"success",[84,88,92,96,101,106,110,115,120,123,126],{"id":22,"doc_module":4,"doc_module_name":25,"category_name":85,"show_sort_weight":86,"slug":87},"Story & Novel",90,"story-novel",{"id":26,"doc_module":4,"doc_module_name":25,"category_name":89,"show_sort_weight":90,"slug":91},"Literature",80,"literature",{"id":33,"doc_module":4,"doc_module_name":25,"category_name":93,"show_sort_weight":94,"slug":95},"Exam",70,"exam",{"id":97,"doc_module":4,"doc_module_name":25,"category_name":98,"show_sort_weight":99,"slug":100},5,"Comic",60,"comic",{"id":102,"doc_module":4,"doc_module_name":25,"category_name":103,"show_sort_weight":104,"slug":105},6,"Technology",50,"technology",{"id":107,"doc_module":4,"doc_module_name":25,"category_name":29,"show_sort_weight":108,"slug":109},7,40,"healthcare",{"id":111,"doc_module":4,"doc_module_name":25,"category_name":112,"show_sort_weight":113,"slug":114},8,"Research & Report",30,"research-report",{"id":116,"doc_module":4,"doc_module_name":25,"category_name":117,"show_sort_weight":118,"slug":119},9,"Religion & Spirituality",20,"religion-spirituality",{"id":118,"doc_module":4,"doc_module_name":25,"category_name":121,"show_sort_weight":118,"slug":122},"World Cup","world-cup",{"id":55,"doc_module":4,"doc_module_name":25,"category_name":124,"show_sort_weight":55,"slug":125},"Lifestyle","lifestyle",{"id":127,"doc_module":4,"doc_module_name":25,"category_name":128,"show_sort_weight":97,"slug":129},19,"General","general",{"code":4,"msg":82,"data":131},{"doc_id":79,"user_id":132,"nickname":42,"user_avatar":133,"doc_module":4,"category_id":107,"category_name":29,"doc_title":10,"doc_description":12,"doc_content":134,"file_id":135,"file_url":136,"file_type":137,"file_size":138,"view_count":55,"is_deleted":4,"is_public":22,"is_downloadable":22,"audit_status":22,"page_count":111,"language":139,"language_code":8,"site_id":7,"html_lang":8,"table_of_contents":140,"faqs":141,"seo_title":142,"seo_description":12,"update_tm":143,"read_time":118,"preview_page_count":4},2336478945519,"https://ap-avatar.wpscdn.com/davatar_085a072bc5b1113ac321206ff7593b45","Wang et al.

A   \ncomparative analysis of digital eye strain and traditional dry eye disease: a prospective comparative study  \nHongjuan Wang 1*, Xueping Zhu 1 and Caiwen Ning2  \nAbstract  \nBackground The study aimed to compare the clinical features, tear-film characteristics, blinking dynamics, and treatment outcomes of patients with Dry Eye Disease (DED) and Digital Eye Strain (DES), and identify predictors of poor response.  \nMethods This prospective comparative study included 264 participants, with 132 patients in each group (DES and DED) . Patients completed the Ocular Surface Disease Index (OSDI) and the Computer Vision Syndrome Questionnaire (CVS-Q) . Objective assessments included tear break-up time (TBUT), Schirmer’s test, fluorescein staining, blink rate, and incomplete blink percentage. Treatment outcomes were evaluated after 4 to 6 weeks. Multivariable models were adjusted for age, sex, screen exposure, baseline OSDI, TBUT, MGD, and blink rate.  \nResults Mean age was similar in both groups (DES: 39.8 years; DED: 41.7 years; p= 0 . 222) . Median OSDI and CVS-Q scores showed no significant differences. TBUT was longer in DES (6 .3 s) vs. DED (5 .1 s; p = 0 . 005), while fluorescein staining was higher in DED (p = 0 . 027) . Schirmer’s test, blink rate, and incomplete blink percentages were comparable. Improvement was seen in 65. 2%(DES) vs. 56. 1%(DED) (p = 0 . 291) . Predictors of poor treatment response included female sex (OR 1. 30; 95% CI 1.05–1. 60; p = 0 . 016), greater daily screen exposure (OR 1. 17; 95% CI 1.02–1. 35; p = 0 . 024), higher baseline OSDI (OR 1.020 per point; 95% CI 1.004–1. 037; p = 0 . 013), and shorter TBUT (OR 0.846 per second; 95% CI 0 .716–0. 999; p = 0 . 048) .  \nConclusions DES and DED demonstrate overlapping but distinct clinical profiles. TBUT, screen time, age, and symptom severity significantly influence treatment outcomes. Tailored therapeutic approaches that address both tear-film instability and screen-related behaviours are essential for optimal management. Findings should be interpreted in light of differing symptom-versus sign-based group definitions.  \nClinical trial number Not applicable.  \nKeywords Dry eye disease, Digital eye strain, Tear film, Blink rate, Treatment response  \n*Correspondence:  \nHongjuan Wang  \n[wanghongjuan2025@163.com](wanghongjuan2025@163.com)  \n1The First Affiliated Hospital of Nanchang Medical College, Jiangxi Provincial People’s Hospital, Nanchang, Jiangxi, China  \n2Jiangxi New Vision Eye Hospital, Nanchang, Jiangxi, China  \n© The Author(s) 2025.
