Increase in choroidal thickness after blue light stimulation of the blind spot in young adults
Bioelectronic MedicineBackground Blue light activates melanopsin, a photopigment that is expressed in intrinsically photosensitive retinal ganglion cells (ipRGCs). The axons of ipRGCs converge on the optic disc, which corresponds to the physiological blind spot in the visual ...

The pathogenesis of Acanthamoeba infections: current status and future implications [PDF]
, 2004 Acanthamoeba are opportunistic protozoan parasites that can cause painful, visionthreatening keratitis. However the pathogenesis and pathophysiology of Acanthamoeba keratitis remain incompletely understood. Most cases of Acanthamoeba keratitis develop

Advanced Functional Materials, EarlyView.Plasmonic hybridization enables control of light emission in 2D van der Waals heterojunctions. By stacking multilayer GaSe and monolayer MoS2 on a silver film, light emission is enhanced at the edges due to plasmonic effects. In the center, where these effects are absent, charge transfer led to reduced light emission.

Kerala Journal of Ophthalmology, 2017 Contact lens is valuable optical aid to vision in the presence of severe refractive error and treatment of certain chronic diseases. Complications can be prevented by precise fitting, regular follow-up, early recognition, and management of complications by an experienced ophthalmologist.

PRINCIPLES OF THE CONTACT LENS
The American Journal of the Medical Sciences, 1947 Treissman, M.B., B.S., F.R.C.S. (Eng.), D.O.M.S., and E. A. Plaice. Price, 10s 6d. Pp. 88, with 40 illustrations. London: Henry Kimpton, 1946. The authors state that "so far as we are aware, no publication has yet appeared in this country which deals with the principles and uses of these lenses." This book must therefore have preceded by a short time ...

Fast Neutron Detector Based on Hybrid 2D Perovskite Thin Films
Advanced Functional Materials, EarlyView.This work presents the direct detection of fast neutrons using flexible hybrid 2D perovskite (PEA2PbBr4) thin‐film detectors. Thanks to their high low‐Z elements content and good charge transport, these materials enable efficient neutron detection. The thin film configuration allowed the operation at low voltage, and offer scalability, flexibility, and
