Current sight-centered designs and services in library and information science (LIS) do not effectively support blind and visually impaired (BVI) users. Simultaneously, there is a lack of studies focused on the research methods utilized in BVI research. This study analyzed 165 research papers retrieved from four LIS databases over a 40-year period. The uniqueness of BVI research methods on research design, data collection, and data analysis is highlighted. While survey and experiment are the two most commonly applied research designs in LIS research, survey and evaluation are the main research designs for BVI research. Concurrently, assessment report is a unique data collection method employed. More quantitative analysis was also applied in BVI research, and most of the qualitative analysis was not specified. This study reveals an opportunity to enhance the diverse approaches to BVI research and further satisfy BVI users' unique needs.

当前图书馆和信息科学 (LIS) 中以视觉为中心的设计和服务不能有效地支持盲人和视障 (BVI) 用户。同时，缺乏针对英属维尔京群岛研究中使用的研究方法的研究。本研究分析了 40 年间从四个 LIS 数据库中检索到的 165 篇研究论文。突出了 BVI 研究方法在研究设计、数据收集和数据分析方面的独特性。虽然调查和实验是 LIS 研究中最常用的两种研究设计，但调查和评估是 BVI 研究的主要研究设计。同时，评估报告是一种独特的数据收集方法。BVI研究也应用了更多的定量分析，大部分定性分析没有具体说明。
