Accuracy and precision of automated subjective refraction in young hyperopes under cycloplegia [PDF]
, 2023 Purpose: To assess the agreement between the Eye Refract, an instrument to perform subjective automated refraction, and the traditional subjective refraction, as the gold standard, in young hyperopes under noncycloplegic and cycloplegic conditions ...

Long-term Visual and Refractive Outcomes of Argon Laser-treated Retinopathy of Prematurity
Journal of Ophthalmic & Vision Research, 2022 Purpose: In this case–control study, we measured visual acuity, objective refraction, ocular biometric parameters, and strabismus in premature cases classified according to the following categories: argon laser-treated retinopathy of prematurity (ROP ...

Observation of discrete-light temporal refraction by moving potentials with broken Galilean invariance [PDF]
Refraction is a basic beam bending effect at two media’s interface. While traditional studies focus on stationary boundaries, moving boundaries or potentials could enable new laws of refractions.

Study on the Polarization Pattern Induced by Wavy Water Surfaces
Remote Sensing, 2023 In nature, the wavy ocean surface is a common polarizer, which can change the polarization state of incident light by refraction and reflection and form a new polarization pattern different from the atmosphere.

JAMA: The Journal of the American Medical Association, 1895 This is an age of prevention rather than of cure. The greatest efforts are being made to cure disease before disease occurs. Can anything more distinctly exemplify the disinterestedness of the physician than his earnest and unremitting efforts towards prophylactic medicine?

Beyond traditional subjective refraction [PDF]
, 2022 Purpose of reviewThe evaluation of refractive error is probably the most important and common procedure in eye care. The gold standard method for evaluating refractive error is subjective refraction, a process that has not significantly changed in ...
