Reading, corneal topography and contact lenses [PDF]
, 2003 Purpose\ud \ud In a previous study we have shown that many individuals have significant changes in the shape and optical characteristics of the cornea following 1 hour of reading.

Prescribing soft contact lenses for astigmatism
, 2009 There have been continued improvements in toric soft lens design over the past three decades. Data that we have gathered from annual contact lens fitting surveys demonstrate a commensurate increase in toric lens fitting as a proportion of all soft lenses

Small, EarlyView.This study presents a robust strategy for 3D printing conductive, mechanically resilient MXene–CNF composite structures using a single‐step freeze‐induced crosslinking method. The printed architectures remain stable in both wet and dry states, exhibit high electrical conductivity and mechanical strength, and demonstrate practical application in fully ...

Soft contact lenses and corneal topography
, 1993 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.

Adhesive Protein Nanoparticles Control Emulsion Properties via Tunable Interdroplet Linking
Small, EarlyView.In this study, pea protein nanoparticles were probed for their ability to link emulsion droplets. Experiments across multiple length scales showed that the nanoparticles form shear‐resistant links via bridging interactions from the thin film between droplets.

Comparison of accommodation with rigid and flexible contact lenses [PDF]
, 1977 Measurements were made of the amplitude of accommodation for myopes wearing spectacles, rigid contact lenses, and flexible contact lenses. Both forms of contact lenses placed greater accommodative requirements on the myope than did spectacle correction ...

HS‐AFM Reveals Hierarchical RNA Folding Driving Condensate Assembly and Material States
Small, EarlyView.High‐speed atomic force microscopy reveals the nanoscale pathway of RNA condensate formation, from individual RNA folding to higher‐order assembly. Quantitative analyses of fusion dynamics and nanomechanical properties distinguish liquid‐like poly A condensates from solid‐like total RNA assemblies, providing a direct link between RNA self‐assembly and ...

Small, EarlyView.Aerosol Jet Printing (AJP), coupled with a novel in situ monitoring method, enabled the controlled fabrication of aligned and crumpled Ti3C2Tx MXenes for diverse applications. Demonstrated across multiple 2D materials, this scalable strategy stablishes flake morphology as a controllable design parameter for engineering application‐specific material ...

Masking of irregular corneal topography with contact lenses
, 1998 PURPOSE: We examined the effectiveness of various types of contact lenses in masking irregular corneal topography using videokeratoscopy, residual aberrations, and measurement of visual acuity.
