Summary: Recent clinical studies have shown that brief exposure to red light may have a significant anti-myopia effect. However, many experimental animals develop myopia in response to this wavelength. In this study, tree shrews were used to investigate the influence of red light's spectral purity, duty cycle, and intensity on its anti-myopic effect.

Summary: Most premium intraocular lenses for presbyopia correction use diffractive optics, but there is limited understanding of the optical principles and clinical outcomes of different designs. This study used an optical bench to assess the optical quality of three lens designs and found that chromatic aberration plays a crucial role in their performance. The results provide useful information for clinicians in selecting the most suitable lens for individual patients.

Summary: This study compared the optical performance of a multizonal presbyopia-correcting intraocular lens (IOL) and a conventional trifocal model. The results showed that both lenses had similar simulated visual acuity (VA) at far focus, but the multizonal-refractive lens had a smaller decrease in VA at -1.0 D compared to the diffractive lens. The multizonal-refractive lens also had slightly better VA prediction at the secondary peak. Overall, the multizonal-refractive lens performed comparably to the trifocal IOL.

Summary: The emmetropization feedback mechanism adjusts the axial growth of eyes based on visual cues to maintain clear focus on distant objects. Existing animal models of myopia do not accurately represent the stimuli that lead to human myopia. In our study, we developed an animal model using tree shrews that better mimics the slow progression of myopia seen in children by providing limited chromatic cues.

Summary: This study aimed to investigate the impact of retinal light stimulation of different wavelength ranges on contrast sensitivity (CS), as well as the reliability and repeatability of a newly developed CS test. Results suggest that using retinal illumination via LCD screens to increase CS is inconclusive.

Summary: Exposure to ambient amber light induced significant hyperopia in the Filter group, while there was no effect on refractive error in the Goggle group. This difference may be attributed to the simultaneous activation of SWS and LWS cones caused by the scattering of broad-band light from the periphery of the goggles.

Summary: Myopia is caused by excessive axial growth of the eye, leading to the abnormal projection of distant images in front of the retina. Exposure to outdoor light plays a crucial role in preventing myopia in children, possibly due to the brightness and blue-shifted spectral composition of sunlight lacking in artificial indoor lighting. The study shows that blue-enriched white light can reduce aberrant ocular elongation and accelerate recovery from form-deprivation, with distinct metabolomic profiles in the eyes depending on the spectral content of ambient light.

Summary: The goal of this experiment was to investigate the interaction between temporal visual stimulation and the spectral properties of the visual environment and autonomic innervation. Selective lesions of the autonomic nervous system were performed in chickens followed by exposure to different types of light stimulation. The results showed that both autonomic lesion and visual stimulation were necessary to affect the growth of ocular components, suggesting a potential mechanism for the control of emmetropization.

Summary: Repeated low-level red-light therapy (RLRL) has emerged as a novel scientific approach for treating myopia by enhancing cellular metabolism and promoting repair processes. RLRL therapy, regulated by cytochrome c oxidase and dopamine-enhanced release of nitric oxide, can inhibit myopia progression and improve visual impairments without adverse effects. Targeting neuronal energy metabolism may be a major strategy for neurotherapeutics of myopia, and RLRL therapy holds great potential in controlling myopia.

Summary: Hydrogel electrolytes have been widely studied in Zn metal batteries for wearable electronics, but the mechanical stability of the hydrogel under repeated deformation has been overlooked, resulting in unsatisfactory performance. This study explores the compressive fatigue-resistance properties of the hydrogel electrolyte and identifies the critical roles of the salt and copolymer matrix in crack initiation and propagation. An optimal Zn(ClO4)(2)-polyacrylamide/chitosan hydrogel electrolyte (C-PAMCS) is found to exhibit an unprecedented lifespan and high areal capacity for Zn//Zn cells, enabling potential applications in flexible Zn-ion batteries.

Summary: This study presents the synthesis of tin selenide nanoparticles grown on highly conductive, porous 3D graphene foam as a stable host for sodium metal anodes and reveals their energy storage mechanism through conversion reactions. The SnSe@GF electrode exhibits remarkable reversibility after 1500 cycles in asymmetric cells and extraordinary cyclic stability and low overpotentials for 2000 h in symmetric cells. The outstanding performance is attributed to the conversion of crystalline SnSe into low-crystallinity Na15Sn4 and Na2Se dual nucleation sites after pre-sodiation, which enables the formation of a unique interface with high sodium affinity and abundant active sites, resulting in uniform sodium nucleation/plating and dendrite suppression.
