Abstract

An electro-active spectacle lens is disclosed. The disclosed lens includes a first lens optic. The disclosed lens also includes a first electro-active zone positioned in a cooperative relationship with the first lens optic. In certain embodiments, the electro-active lens includes a range finder positioned in a cooperative relationship with the electro-active lens.

Claims

1. An apparatus for determining the refraction and aberrations of a patient'"'"'s eye focused on an external physical target, comprising:

a light source;

optics directing light from said light source to the patient'"'"'s eye;

a test lens having an optical power, said test lens disposable in an optical path between the patient'"'"'s eye and said external physical target, such that the patient'"'"'s eye looking at said external physical target receives light from said light source through the lens;

at least one wavefront measurement device positioned to detect aberrations in light returning from the patient'"'"'s eye;

a housing containing said optics and said test lens, said housing having an input port and an output port, said optical path between the patient'"'"'s eye and said physical target passing through said input port into said housing and through said output port thereby exiting said housing, said target being external to said housing; and

processing electronics configured to compute variation in multiple wavefront measurements performed by said wavefront measurement device using said test lens having said optical power to measure a patient'"'"'s subjective response to said optical power.

2. The apparatus of claim 1, wherein the wavefront measurement device includes at least one light detector receiving a wavefront from the light returning from the patient'"'"'s eye, and outputting a signal representative of the aberrations.

3. The apparatus of claim 2, wherein the wavefront measurement device includes electronics that outputs a diagnostic signal substantially instantly, and wherein said diagnostic signal corresponds to the objective assessment of quality of vision.

4. An apparatus for determining the refraction of a patient'"'"'s eye focused on a physical target, said apparatus comprising:

a light source;

optics directing light from said light source to the patient'"'"'s eye, said light reflecting from a surface of said eye, said reflected light comprising a plurality of wavefronts;

a wavefront measurement device positioned along a first optical path to said eye to measure the shape of said wavefronts reflected from the patient'"'"'s eye;

at least one test lens disposable along a second optical path between the patient'"'"'s eye and the physical target; and

processing electronics configured to determine the variation in multiple wavefront measurements that are performed by said wavefront measurement device for a fixed amount of refractive correction using said at least one test lens having said fixed refractive correction to quantify accommodation of the patient'"'"'s eye,

wherein said optics and said at least one test lens are arranged such that when said patient looks at said physical target through said test lens, said light from said light source is directed through said eye so as to determine said refraction from said wavefronts returning from said eye,

further wherein said at least one lens comprises a plurality of test lens having different amounts of refractive correction, wherein said processing electronics are configured to determine variation in multiple wavefront measurements for each of said plurality of test lens so as to quantify accommodation of the patient'"'"'s eye for each of said plurality of test lens.
