The ability to perform many daily tasks relies on good visual acuity at various distances. A review of existing measures of visual function revealed gaps in task content, particularly tasks that rely on intermediate vision.
This research sought to extend the content base and visual range coverage of tasks used to assess visual function.
Ophthalmology patients (n = 72) with myopia, hyperopia, presbyopia, astigmatism, cataracts, and/or glaucoma were involved in various qualitative sub-studies, including life event journaling, telephone interviews, and both on-line and face-to-face focus groups. The resulting journal entries and transcripts were thematically analyzed to identify visual tasks that rely on visual acuity in the near, intermediate, and distant visual ranges.
A wide variety of distance-specific visual tasks were identified. Certain types of tasks relied on distance vision, such as; ambulation, driving, leisure and sports, and social functions. Other task groupings such as technology use and activities of daily living relied primarily on near and intermediate vision. Two new content areas were identified, technology use and safe task performance.
This thematic analysis provides a rich body of information about tasks that affect daily life and are made more difficult by poor visual acuity at various distance ranges.
完成许多日常任务的能力依赖于不同距离的良好视力。对现有视觉功能测量方法的回顾显示，在任务内容方面存在差距，特别是依赖于中间视觉的任务。
本研究旨在扩展用于评估视觉功能的任务的内容基础和视觉范围覆盖。
近视、远视、老视、散光、白内障和/或青光眼的眼科患者（n=72）参与了各种定性子研究，包括生活事件日志、电话访谈以及在线和面对面的焦点小组。对生成的日志条目和转录本进行主题分析，以确定依赖近、中、远距离视力的视觉任务。
确定了各种各样的特定距离的视觉任务。某些类型的任务依赖于远距离视觉，例如：步行、驾驶、休闲和运动以及社交功能。其他任务分组，如技术使用和日常生活活动，主要依赖于近和中距离视觉。确定了两个新的内容领域，即技术使用和安全任务执行。
这项主题分析提供了大量关于影响日常生活的任务的信息，这些任务在不同的距离范围内由于视力不佳而变得更加困难。
