A method for determining an individual's vision prescription, comprising the activities of:
- refracting the individual using an electro-active lens;
- and
- obtaining a correction needed for the individual,
- the correction obtained including a correction for the astigmatic error of the individual.
A method for determining an individual's vision prescription, comprising the activities of:
- refracting the individual using an electro-active lens;
- obtaining a correction needed for the individual;
- and
- measuring the individual's ocular aberrations using a wavefront analyzer.
A method for determining an individual's vision prescription, comprising the activities of:
- refracting the individual using an electro-active lens;

A method for dispensing electro-active spectacles comprising the activities of:
- obtaining a correction needed for a wearer of the electro-active spectacles by refracting the wearer with an electro-active lens,
- the correction obtained including a correction for the astigmatic error of the individual;
- and
- providing the electro-active spectacles containing the correction.
A method for refracting and dispensing eye glasses having a lens for a patient comprising the activities of:
- placing an electro-active lens within the patient's line of sight;
- and
- refracting the patient to measure a correction needed for the patient,
- the correction obtained including a correction for the astigmatic error of the individual.
A method for adjusting electro-active spectacles comprising the activities of:
- obtaining a correction needed for a wearer of the electro-active spectacles by subjectively refracting the wearer with an electro-active lens,
- the correction obtained including a correction for the astigmatic error of the wearer;
- and
- modifying the electro-active spectacles to provide the needed correction.
A method for constructing an electro-active lens comprising the activities of:
- providing a single lens having a first surface, a second surface, and an outer perimeter edge;
- associating an electro-active zone with the single lens,
- the electro-active zone having at least two pixels;
- and
- removing at least a portion of the outer perimeter edge of the single lens to reconfigure the shape of the single lens to conform to an eyeglass frame.
An electro-active lens comprising:
- a single optical lens having a first surface, a second surface, and an outer perimeter edge;
- and
- an electro-active zone supported by the single optical lens,
- the electro-active zone having at least two pixels,
- the electro-active zone sized to be contained within the outer perimeter edge of the single optical lens,
- the outer perimeter edge of the single optical lens being removable to conform the shape of the single optical lens to an eyeglass frame.
An electro-active lens comprising:
- a single optical lens having a first surface, a second surface, and an outer perimeter edge;
- and
- an electro-active zone supported by the single optical lens,
- the electro-active zone having at least two layers of pixelated regions,
- the electro-active zone having an outer perimeter edge.
