Defects in disposable contact lenses can compromise ocular integrity
To ascertain the prevalence of defects in disposable contact lenses, an Optimec JFC contact lens analyser (×16 magnification) was used to examine 150 Acuvue, 150 NewVues, and 150 SeeQuence lenses, all -3.00D in power.

Generating Unconventional Spin‐Orbit Torques With Patterned Phase Gradients in Tungsten Thin Films
ABSTRACT A key aim in spintronics is to achieve current‐induced magnetization switching via spin‐orbit torques without external magnetic fields. For this, the focus of recent work has been on introducing controlled lateral gradients across ferromagnet/heavy‐metal devices, giving variations in thickness, composition, or interface quality.

Prevention and treatment of corneal injury in people wearing soft contact lenses
Contact lenses are a widely used alternative to glasses. However, wearing contact lenses, especially in violation of directions for use, often results in corneal injury.

Soft contact lenses and corneal topography
We investigated the effect of 3 months of daily soft contact lenswear on corneal\ud topography. Thirty young myopic subjects who had not previously worn contact\ud lenses were fitted with hydroxyethyl methacrylate (HEMA) soft lenses.

Intrinsic material dynamics are harnessed as computational resources for neuromorphic in‐materio physical reservoir computing. Defects, ionic motion, interfaces, percolation, geometry, and biasing shape transient states that provide fading memory, nonlinearity, and high‐dimensional projection for simple readout.

Effects of short-term wear of silicone hydrogel contact lenses on refractive behaviour
Contact lens wear is known to induce change in both the cornea and refractive state. Often a shift towards increased myopia is noted. Historically investigations into the effects of contact lenses onrefractive state have often been incomplete in terms of
