Caring for caregivers of low vision individuals
The prevalence of adults with low vision has increased dramatically in rapidly aging countries. While research has shown that physical and psychosocial factors affect the quality of life of caregivers for low-vision individuals, there is still a lack of understanding of the caregiver's experiences in a fast-aging developing Asian country, like ...

3D Printed Photon Shield Assembly for Low‐Noise Visual Stimulation During Two‐Photon Imaging in Mice
Advanced Materials Technologies, EarlyView.We present the Photon Shield, an open‐hardware system for low‐noise two‐photon calcium imaging during visual stimulation in mice. Combining a 3D‐printed headplate and rail‐mounted shield substantially reduces stray‐light contamination, as quantitatively verified. Functional validation confirms reliable cortical responses. Open design files enable broad

Providing low vision care requires multidisciplinary collaboration
, 2018 Coping with the consequences of vision loss is complex and difficult, especially after a lifetime as a sighted person. Successful vision rehabilitation and sound user pathways are not only a prerequisite for the older adult and for active ageing, but for

Dynamic Fluorescence Modulation via Light‐Driven Competitive Protonation
Advanced Optical Materials, EarlyView.A two‐component molecular system demonstrates reversible, light‐driven fluorescence write–erase cycling and thermal imaging. Illumination of a merocyanine photoacid transfers a proton to a highly efficient fluorescent pyridinium dye, switching its emission color; thermal relaxation reverses the process in the dark.

Geometry‐Driven Whispering‐Gallery Modes in Self‐Assembled Phosphorescent Organic Microtubes
Advanced Optical Materials, EarlyView.Micelles encapsulating tris(2‐phenylpyridine)iridium(III) self‐assemble into a hollow hexagonal microtube stabilized by a surface passivation layer. The hexagonal cross‐section confines circulating light along its facets, sustaining sharp whispering‐gallery resonances that guide photoluminescence emission under laser excitation.
