Abstract
Se revela un foróptero electroactivo y un método de usar el foróptero electroactivo para medir una prescripción de visión del paciente. El foróptero electroactivo incluye una serie de lentes electroactivas a las que se puede dirigir individualmente. Las lentes tienen o bien una potencia óptica positiva o negativa cuando se aplica un potencial eléctrico a través de la lente y una potencia óptica neutra cuando no se aplica potencial eléctrico a través de la lente. Cada lente provee una potencia óptica que es parte de una potencia óptica neta de la serie de lentes cuando un paciente ve a través del foróptero. La potencia óptica del foróptero puede ser ajustada incrementalmente cambiando la distribución del potencial eléctrico a través de diferentes lentes de la serie para proveer potencia óptica creciente o decreciente hasta que un paciente alcanza un nivel deseado de claridad y se ha determinado una prescripción de visión.An electroactive phoropter and a method of using the electroactive phoropter to measure a patient's vision prescription are revealed. The electroactive phoropter includes a series of electroactive lenses that can be addressed individually. The lenses have either a positive or negative optical power when an electrical potential is applied through the lens and a neutral optical power when no electrical potential is applied through the lens. Each lens provides an optical power that is part of a net optical power of the lens series when a patient sees through the phoropter. The optic power of the phoropter can be incrementally adjusted by changing the distribution of the electrical potential through different lenses of the series to provide increasing or decreasing optical power until a patient reaches a desired level of clarity and a vision prescription has been determined.
