“…While these reports cannot be assigned to any of the previous sections, their findings have contributed to the field of optometry. Some of the studies described were designed to determine how much time one needs to fixate during different tasks (Belyaev et al, 2020;Bowers et al, 2021;Chaudhary et al, 2020;Ivanchenko et al, 2019;Kelly et al, 2019b;Ratnam et al, 2018;Seemiller et al, 2018), whether fixation stability leads to reduced head movements in people with Argus II (Caspi et al, 2018), or whether this stability differs between central and peripheral vision (Raveendran et al, 2020).…”

This systematic review examines the use of eye-tracking devices in optometry, describing their main characteristics, areas of application and metrics used. Using the PRISMA method, a systematic search was performed of three databases. The search strategy identified 141 reports relevant to this topic, indicating the exponential growth over the past ten years of the use of eye trackers in optometry. Eye-tracking technology was applied in at least 12 areas of the field of optometry and rehabilitation, the main ones being optometric device technology, and the assessment, treatment, and analysis of ocular disorders. The main devices reported on were infrared light-based and had an image capture frequency of 60 Hz to 2000 Hz. The main metrics mentioned were fixations, saccadic movements, smooth pursuit, microsaccades, and pupil variables. Study quality was sometimes limited in that incomplete information was provided regarding the devices used, the study design, the methods used, participants' visual function and statistical treatment of data. While there is still a need for more research in this area, eye-tracking devices should be more actively incorporated as a useful tool with both clinical and research applications. This review highlights the robustness this technology offers to obtain objective information about a person's vision in terms of optometry and visual function, with implications for improving visual health services and our understanding of the vision process.
