Summary: This study aimed to determine the diagnostic agreement between non-cycloplegic and cycloplegic refraction in children. The results showed that non-cycloplegic Plusoptix was the most useful autorefractor for estimating refractive error in young children with low to moderate levels of hyperopia. However, when measuring refractive error in children aged <= 12 years, cycloplegic refraction should remain the test of choice.

Summary: Through simulations, it was found that Grand-Seiko autorefractors with annular targets are likely to provide valid peripheral refractions. The results were closer to Zernike refractions and spherical aberration had up to 0.5D impact on refraction, while peripheral coma had limited influence.

Summary: This study uses simulations to investigate the effect of lateral misalignment of the Grand-Seiko WR-5100K autorefractor on peripheral refraction. The results show that misalignment causes significant errors in peripheral refraction, with greater effects when misalignment and visual field are in opposite directions.

Summary: This paper introduces a novel wide-angle refraction measurement method called Refraction Topography (RT), and evaluates its agreement with simulation results and expected refraction. RT utilizes a refraction algorithm on fundus images to measure refraction. Unlike traditional methods, RT requires the subject to stare at a stationary target. The study demonstrates the agreement between the test results obtained using RT, simulation results, and expected refraction on three test eyes.

Summary: The study found that eye diseases increase the risk of arthritis, with cataracts being the most significant factor, and different eye diseases affect osteoarthritis, rheumatoid arthritis, and other types of arthritis to varying degrees.

Summary: The study focused on the optical principles and properties of autorefractors that use the image-size principle. It was found that when light is diverging, hyperopia produces greater retinal image sizes than myopia; conversely, when light is converging, the opposite is true.

Summary: This study compares the effects of four myopia control interventions on peripheral vision and image quality. Multiple evaluation methods are needed to fully quantify the optical effects of these interventions. Perifocal has a larger variation in the effect on peripheral vision and interacts with natural optical errors. MiSight has a smaller effect on peripheral refraction but a greater effect on peripheral vision. Stellest and MiyoSmart have small effects on peripheral refraction but indicate reduced retinal contrast for all participants.

Summary: This study evaluates the perceptual response of the human visual system to periodic changes in defocus using tunable lenses. It shows that the task of minimizing flicker by varying the average optical power is more repeatable and faster than the task of minimizing blur. This discovery can be used to develop new methods for measuring refractive error with improved accuracy, precision, and efficiency.

Summary: Birds with larger eye sizes tend to reside in dense habitats, feed on invertebrates or vertebrates, and have larger brains. However, eye size does not seem to be influenced by migration behavior or foraging habitat. The primary factors shaping avian eye size evolution are habitat openness, food type, and cognitive ability.

Summary: The study focuses on potential errors in pupillometry measurement, specifically looking at eyeball rotation in relation to the recording camera and optical effects due to refraction at corneal interfaces. Through experimental data and synthetic images, a successful correction method is identified, along with discussions on the impact of errors at different levels.

Summary: This study compared oculomotor performances in elderly depressed patients with and without suicidal behaviors, finding that patients with suicidal behaviors had fewer corrected AS errors and took longer to correct them. The research suggests that suicidal patients may have higher cognitive inflexibility, which could explain their difficulty in responding adequately to stressful environments and suicidal ideation.

Summary: Individualized optical modelling of the eye is a useful tool to estimate optical properties from geometrical parameters. This study extended the modeling to the peripheral retina, using corneal geometry and axial distances. The final model showed high agreement with measured optical quality for spherical equivalent and J0 astigmatism.

Summary: The study identified two types of SDO and found that the frequency and amplitude of SDO were positively correlated with the peak velocity and deceleration of main saccades, with a significant increase in elderly subjects. However, there were no significant differences among the three elderly groups.

Summary: The study estimated geometric plume heights for the daytime eruptions of La Soufriere in April 2021 using visible red band geostationary side views and geostationary-polar orbiter stereo views. The research found that the tropospheric lower bound of the radiometric height range always underestimated the geometric height by a couple of kilometers.

Summary: Photonic time crystals (PTCs) with periodically modulated dielectric permittivity offer new possibilities for light manipulation. In this study, we theoretically investigate the emission of light from a radiation source inside a PTC and observe exponential amplification of radiation corresponding to the momentum bandgap. The radiation linewidth narrows over time, eventually becoming monochromatic in the middle of the bandgap, which leads to the proposal of a nonresonant tunable PTC laser. Furthermore, we find that the spontaneous decay rate of an atom embedded in a PTC vanishes at the band edge due to the low density of photonic states.
