The binocular accommodative response in uncorrected ametropia.
PURPOSE To measure the changes in astigmatism and in the degree of anisometropia when ametropes respond to accommodative stimulation. METHODS The accommodative responses of ametropes were binocularly measured with an improved photorefractometer (PR-1100), which objectively measured binocular refraction in all meridians simultaneously, when a visual fixation target was shown in natural space a...
متن کاملRetinal image in axial and refractive ametropia.
THERE are some features relative to the size of the retinal images in these two conditions which are of general interest, though they are rarely discussed. Axial Ametropia.-The " basic " (blurred) retinal image is smallest in hyperopia, intermediate in emmetropia, and largest in myopia. The size of a blurred retinal image is best taken from the points in the diffusion circles at the extremities...

Microscopic work distribution of small systems in quantum isothermal processes and the minimal work principle.
For a two-level quantum mechanical system, we derive microscopically the exact expression for the fluctuation of microscopic work in a multistep nonequilibrium process, and we rigorously prove that in an isothermal process, the fluctuation is vanishingly small and the most probabilistic work is just equal to the difference of the free energy. Our study demonstrates that the convergence of the m...
متن کاملLenticular accommodation in relation to ametropia: the chick model.
Our goal was to determine whether experimentally induced ametropias have an effect on lenticular accommodation and spherical aberration. Form-deprivation myopia and hyperopia were induced in one eye of hatchling chicks by application of a translucent goggle and +15 D lens, respectively. After 7 days, eyes were enucleated and lenses were optically scanned prior to accommodation, during accommoda...
