The purpose of this study was to analyze corneal sub-basal nerve plexus (SBNP) density and morphology and their relationships with corneal parameters and refractive status. In this single center study ...

Microscopic crystals in tantalum disulfide have a starring role in what could become a hit for 3-D displays, virtual reality and even self-driving vehicles. A two-dimensional array of the material has ...

A three-dimensional retinal shape was reconstructed by refractive topography (RT). Methods: The personalized optical models of the human eye were reconstructed based on geometric parameters from ...

WXMI — In our science experiment today, we look at a disappearing coin trick, which really is no trick at all. It illustrates density and refraction. Some things are more dense (or heavier) than other ...
