Summary: This study analyzed the correlation between eye movements and asthenopia, and explored the possibility of using eye-tracking techniques for objective assessment of asthenopia. The results showed a positive correlation between the severity of asthenopia and certain eye movement parameters, particularly a decrease in fixation duration and counts. Eye tracking was found to be an effective tool for assessing asthenopia.

Summary: The study focuses on creating shape-adaptive imagers using kirigami design in ultrathin silicon pixels, with high pixel fill factors. These imagers can adjust shape for imaging applications requiring low optical aberration and tunable focusing power. Additionally, combining a concave-shaped imager with a tunable lens allows for adaptive optical focus to capture distant and near objects with low aberration.

Summary: Current evidence demonstrates the effectiveness of vision training for presbyopia. This study developed and tested a training program using alternating focal distances. The results showed that both alternating-distance training and fixed-distance training were effective in improving visual acuity and preventing deterioration in presbyopia.

Summary: This study reevaluated the accuracy of the defocus curve (DC) method in assessing visual performance and found that it is equivalent in precision and accuracy to the varying test distance (VD) method. However, the DC method is more practical for clinical use.

Summary: The aim of this study was to investigate the effects of atropine on patients' perception of visual quality after trabeculectomy. Patients who received atropine eye drops described a greater and longer-lasting reduction in visual quality than those who did not receive atropine eye drops. Thus, unless there is an underlying medical necessity, we would discourage the application of atropine as a standard therapy for trabeculectomy surgery.

Summary: This paper proposes a new visual cognitive graph model to describe visual attention allocation associated with task context and utilizes data mining methods to reveal the operator's tacit knowledge during operation tasks. Three physical quantities derived from graph theory are introduced to describe the tacit knowledge, which can be used for constructing interaction systems and operator training.

Summary: The research demonstrates that both chromatic and monochromatic aberrations in the eye affect the optical quality of images projected on the retina, but their combination is not always simply additive, and the eye has a high degree of adaptability to blur.

Summary: The study evaluated the relationship between visual acuity and eye-related quality of life and functional vision in children across different eye conditions using the Pediatric Eye Questionnaire (PedEyeQ). Results showed a significant negative correlation between worse-seeing-eye VA and PedEyeQ scores, indicating that both better-seeing-eye and worse-seeing-eye VA were associated with functional vision and eye-related quality of life in children.

Summary: Cortical activity recorded via electroencephalography is related to an individual's refractive error, but the specific optical metric that modulates this response is unclear. In this study, we measured both brain activity and retinal defocus of visual stimuli with varying levels of spherical blur. Contrary to existing literature, we found that the cortical response to overcorrections follows a sigmoidal shape rather than the classical bell shape, with the inflection point corresponding to subjective refraction and the stimulus being in focus on the retina. However, the amplitude of the cortical response does not seem to accurately indicate the degree of focus on the retina.

Summary: This study objectively evaluated visual discomfort after a 21-min reading session on an iPad and an Ebook using an eye tracker and aberrometer. The results showed no significant differences in eye movements and retinal thickness between the two devices, but variations were observed in post-reading situations depending on the device used.

Summary: The purpose of this study was to investigate the binocular vision status in normally-sighted school aged children who used digital devices. The results showed that children who used digital devices for a longer period of time had significantly reduced amplitudes of accommodation, accommodative facility, and positive fusional vergence.

Summary: The study evaluated the image quality of intraocular lenses using field-tracing optical simulation and compared it with conventional ray-tracing simulation. Results showed that the field-tracing simulation was more precise in representing experimental results for IOL decentration and tilt compared to ray tracing.

Summary: The study found that there are small changes in both the power and axis of astigmatism during accommodation, especially when convergence is involved. These changes in astigmatism may be attributed to shifts in the position of the crystalline lens during accommodation.
