Abstract
A spectacle lens is disclosed. The disclosed lens provides a vision correcting area for the correction of a wearer's refractive error. The viewing correction area provides correction for non-conventional refractive error to provide at least a part of the wearer's vision correction. The lens has a prescription based on a wave front analysis of the wearer's eye and the lens can further be modified to fit within an eyeglass frame.
Claims13
An optical measuring system for quantifying a refractive error of a human eye comprising:
- a means for altering a path of light;
- and
- a wave-front analyzer capable of quantifying a refractive error of a human eye,
- wherein quantifying the refractive error comprises receiving non-passive input from the human, and wherein the means for altering the path of light comprises an adaptive optic modified as the human provides information.
1 more element
A method for determining refractive error of an eye of a person, comprising:
- using a wave-front analyzer to measure a first refractive error of the person's eye, the first refractive error comprising at least one refractive error other than myopia, hyperopia, or prespbyopia;
- generating a first optical power based at least in part on the first refractive error;
- receiving a first non-passive conscious input from the person sensing the first optical power;
- and
- adjusting the first optical power based at least in part upon the first non-passive conscious input, to generate a second optical power.
