In this study, we aimed to validate a novel light field virtual reality (LFVR) system for estimating refractive errors in the human eye. Fifty participants with an average age of 22.12 ± 2.2 years (range 20–30 years) were enrolled. The present study compared spherical equivalent (SE) and focal line measurements (F1 and F2) obtained by the LFVR system with those obtained by established methods, including closed-field and open-field autorefractors, retinoscopy, and subjective refraction. The results showed substantial agreement between the LFVR system and the traditional methods, with intraclass correlation coefficients (ICC) for SE ranging from 82.7% to 86.7% (p < 0.01), and for F1 and F2 from 80.7% to 86.4% (p < 0.01). Intra-repeatability for F1 and F2 demonstrated strong agreement, with ICC values of 88.8% and 97.5%, respectively. These findings suggest that the LFVR system holds potential as a primary tool for refractive error measurement in optical care, offering high agreement and repeatability compared to conventional methods.

In Taiwan, issues in technology education (TE), such as indeterminate core mission and unclear role, could be addressed through an objective knowledge map of research to discern directions of development and prospects. This study explores sub-fields, genres, characteristics, and trends in TE research in Chinese and English over 24 years through bibliometric co-citation analysis using two databases: Web of Science and Airiti Library. As per the findings: (1) TE research has been progressing slowly in Taiwan, while it is developing rapidly elsewhere; Disciplines integrated with TE include education and educational research, engineering, computer science, social sciences, and medicine; (2) Research topics have evolved from industrial arts, technical and vocational education, technological literacy education, and curriculum development, to pedagogical skills of teachers of technology; Other countries focus on "professional development of technology teachers," while Taiwan emphasizes "curriculum and teaching materials;" (3) Clusters from different periods are complementary, and research topics and fronts reflect continuity. (4) "Assessment," as a research dimension, has received insufficient attention. Insights into the evolution of research topics and research fronts are offered for technology educators.
