As children and adolescents are in a critical period of visual development, the presence of asthenopia may lead to an earlier onset and increased prevalence of a range of chronic eye diseases and retinal disorders, thereby affecting their physical and mental health as well as future development. However, existing studies have mostly focused on single interventions, lacking a systematic comparison of the effects of multiple myopia control approaches on asthenopia. Therefore, the present study aims to investigate, through a cross-sectional survey, the impact of various myopia control interventions-including conventional spectacles, defocus-inducing spectacles, orthokeratology, low-concentration atropine, red-light therapy, and combined multi-intervention strategies-on asthenopia, to assess the prevalence and severity of asthenopia among users of different interventions, and to compare the differences in their effects on asthenopia. This will provide evidence-based support for the selection of individualised correction strategies in clinical practice and contribute to advancing clinical research on asthenopia in children and adolescents.",[60,28],"Myopia","2026-07-02",{"date":63,"type":40},"2026-07-09",{"date":65,"type":22},"2026-07-05",{"date":67,"type":22},"2027-04-30",{"name":69,"class":46},"Tianjin Medical University Eye Hospital",{"id":71,"slug":72,"hasResults":11,"nctId":73,"briefTitle":74,"officialTitle":74,"acronym":4,"eligibilityCriteria":75,"healthyVolunteers":16,"sex":17,"minAge":76,"maxAge":77,"enrollmentInfo":78,"targetDuration":4,"studyType":23,"phases":80,"briefSummary":81,"conditions":82,"keywords":86,"overallStatus":92,"whyStopped":4,"lastUpdateSubmitDate":93,"lastUpdatePostDateStruct":94,"startDateStruct":96,"completionDateStruct":98,"leadSponsor":100,"locationsCount":47},"100559906","discussion-on-the-effectiveness-of-tea-on-blood-pressure-body-composition-and-vision-problems-in-college-students-100559906","NCT06570226","Discussion on the Effectiveness of Tea on Blood Pressure, Body Composition and Vision Problems in College Students","Inclusion Criteria:\n\n* The inclusion criteria are college students aged 15 to 22 years old. -\n\nExclusion Criteria:\n\n* hemodialysis patients who need to limit their water intake\n* those with a history of gastric ulcers\n* those allergic to anthocyanins\n* those who have long-term consumption or consumption of beverages, foods or health products containing high anthocyanins that may interfere with the study after evaluation, for example: foods or health foods such as cranberries, blueberries, cherries and grapes.","15 Years","22 Years",{"count":79,"type":22},100,[25],"Background:\n\nTea is a universal beverage and one of the most popular drinks around the world. Some cell and animal experiments have pointed out that drinking tea may be related to hypotension, body composition and vision problems, and there are more and more related advertisements, especially for hibiscus tea, which is rich in anthocyanins. However, there is a lack of literature on the effectiveness of hibiscus tea drinks in preventing and treating blood pressure, body composition and vision problems in college students.\n\nPurposes:\n\nThis study used a randomized human trial to evaluate the effects of drinking hibiscus tea on the control and reduction of blood pressure, body composition, and near vision problems. 100 subjects were divided into 2 groups: the hibiscus tea group and the boiled water drinking group, and they continued to drink it for 10 weeks. At the beginning of the trial (week zero), the second week, the sixth week, and the tenth week after stopping drinking, the visual fatigue scale, blood pressure, and body composition were examined respectively.
