摘要： PROBLEM TO BE SOLVED: To provide certain advantages in which the fellow eye is working simultaneously with the tasted eye looking at an unobstructed visual target in a lane by generating an image internally capable of moving and manipulating with relative ease.SOLUTION: There are provided an apparatus and a method for measuring refractive characteristics of human eyes comprising an objective refraction measuring device for measuring refraction in at least one eye, an objective refraction measuring system 10 having a proximal end and a distal end and suitable for looking in the proximal end and seeing out the distal end, and an open field visual target 50. A viewing lane 20 is provided between eyes 42, 44 and the open field visual target 50. The viewing lane has sufficient length to allow for focusing the eye at infinity and for natural accommodation at true distance targets near distances such as reading distances. The objective refraction measuring device can be positioned in the viewing lane to measure the eye while the eye is focused on the open field visual target.

摘要： An instrument for measuring aberration refraction of an eye is provided, having: a lens system defining an instrument optical axis and an alignment device for aligning the visual axis of the eye with the instrument optical axis. A light source ( 1 ) produces a probing beam that is projected through the lens system parallel to the instrument optical axis and is selectably positionable partially off-set from the instrument optical axis for entering the eye ( 15 ) parallel to the instrument optical axis at a plurality of locations on the cornea of the eye. A photodetector ( 19 ) measures the position of probing beam light scattered back from the retina of the eye to measure aberration refraction of the eye at a plurality of locations.

A viewing lane (20) is provided between the e ye (42) and (44) the open field visual target (50), the viewing lane has sufficient length to allow for focusing the eye at infinity and for natural accommodation at true distance targets, such near distances such as reading distances. The objective refraction measuring device can be positioned in th e viewing lane to measure the eye while the eye is focused on the open field visual target. In one embodiment the objective refraction measuring device m ay measure refraction characteristics of an eye continuously, substantially continuously or incrementally during dynamic accommodation or changes of the lighting conditions while providing true distance visual targets with the op en field of view through the apparatus. In another embodiment the device objectively measures refraction characteristics of both eyes working togethe r when viewing the open field visual target.

摘要： Eye refraction is measured to achieve desired quality via a selected vision characteristics. A characteristic of vision is selected to correlate to the desired quality of vision from a group of vision characteristics comprising acuity, Strehl ratio, contrast sensitivity, night vision, day vision, and depth of focus, dynamic refraction over a period of time during focus accommodation, and dynamic refraction over a period of time during pupil constriction and dilation. Wavefront aberration measurements are used to objectively measure the state of the eye refraction that defines the desired vision characteristic. The measured state of refraction is expressed with a mathematical function enabling correction of the pre-selected vision characteristic to achieve the desired quality of vision. The mathematical expression function may be a Zernike polynomial having both second order and higher order terms or a function determined by spline mathematical calculations. Pre-selected vision characteristics may be determined using ray tracing technology.

摘要： Se proporciona un instrumento que mide, en forma sincronizada, los errores de refraccion del sistema optico de un ojo y sus componentes refractivos que tienen: un sistema de lentes que define un eje optico del instrumento y un dispositivo de alineacion que sincroniza el eje visual del ojo con el eje optico del instrumento. Una fuente luminosa (120) produce un haz de sondeo (122) que es proyectado a traves del sistema de lentes paralelo al eje optico del instrumento y es susceptible de ser selectivamente colocado, en forma parcial, desplazado del eje optico del instrumento para entras al ojo, paralelo al eje optico del instrumento en una pluralidad de posiciones de la abertura de ojo. Un primer fotodetector (144) mide la posicion de una primera porcion de la reflexion difusa del haz luminoso de sondeo que proviene de la retina (135) del ojo (130) a fin de determinar el error de refraccion total del sistema optico del ojo en una pluralidad de posiciones. Un segundo fotodetector (156) mide, en forma sincronizada, la posicion de una segunda porcion de la reflexion difusa del haz luminoso de sondeo reflejada de regreso a partir de las corneas de los ojos a fin de determinar la forma de la cornea (131) y de esta manera, derivar los otros componentes refractivos.
