Systems, apparatus, and methods for regulating refractive error development through the modulation of peripheral distortion
In general, one aspect disclosed features a spectacle lens, comprising: a central zone having an optical center corresponding to the visual axis of an eye of a patient; and a peripheral zone peripheral to the central zone and comprising: a first zone having a first thickness, and a second zone having a second thickness, wherein: the second thickness varies from the first thickness, and a distance from the second zone to the optical center of the central zone is selected to generate pincushion distortion or barrel distortion in the eye of the patient.
1. A spectacle lens, comprising:
a central zone having an optical center corresponding to the visual axis of an eye of a patient; and
a peripheral zone peripheral to the central zone and comprising: a first zone having a first thickness, and
a second zone having a second thickness, wherein:
the second thickness varies from the first thickness, and
a distance from the second zone to the optical center of the central zone is selected to generate pincushion distortion or barrel distortion in the eye of the patient.
2. The spectacle lens of claim 1 , wherein the second zone comprises at least one of:
a raised area on an anterior surface of the spectacle lens; a
raised area on a posterior surface of the spectacle lens;
a depressed area on an anterior surface of the spectacle lens; or a depressed area on a posterior surface of the spectacle lens.
3. The spectacle lens of claim 1 , wherein:
the second thickness is selected to generate peripheral defocus in the eye of the patient.
4. The spectacle lens of claim 1 , wherein:
the central zone includes a conic-section curve configured to generate a spherical aberration in the eye of the patient.
5. The spectacle lens of claim 4 , wherein:
the spherical aberration generated in the eye of the patient is one of a positive, negative or neutral spherical aberration.
6. The spectacle lens of claim 1 , wherein:
the second thickness in the second zone is selected to generate a different peripheral defocus in the eye of the patient in two or more semi-meridians.
7. The spectacle lens of claim 1 , wherein:
the distance of the second zone to the center of the central zone is selected to generate different amounts of pincushion distortion or barrel distortion in the eye of the patient in two or more semi-meridians.
8. The spectacle lens of claim 1 , wherein:
the spectacle lens has a colorant added to the material or surface of the film to alter the spectral transmission of the spectacle lens.
9. The spectacle lens of claim 1 , wherein:
light sources are housed within the spectacle lens or on the surface of the spectacle lens for directing wavelength specific light into the eye of the patient.
10. A method for defining a spectacle lens to be manufactured for an eye of a patient, comprising:
selecting a central zone having an optical center corresponding to the visual axis of an eye of the patient; and
selecting a peripheral zone peripheral to the central zone; and selecting, for the peripheral zone:
a first zone having a first thickness, and
a second zone having a second thickness, wherein:
the second thickness varies from the first thickness, and
a distance from the second zone to the optical center of the central zone is selected to generate pincushion distortion or barrel distortion in the eye of the patient.
11. The method of claim 10 , further comprising:
selecting, for the second zone, at least one of:
a raised area on an anterior surface of the spectacle lens; a raised area on a posterior surface of the spectacle lens;
a depressed area on an anterior surface of the spectacle lens; or a depressed area on a posterior surface of the spectacle lens.
12. The method of claim 10 , further comprising:
selecting the second thickness to generate peripheral defocus in the eye of the patient.
13. The method of claim 10 , further comprising:
selecting, for the central zone, a conic-section curve to generate a spherical aberration in the eye of the patient.
14. The method of claim 13 , wherein:
the spherical aberration generated in the eye of the patient is one of a positive, negative or neutral spherical aberration.
15. The method of claim 10 , further comprising:
selecting the second thickness in the second zone to generate a different peripheral defocus in the eye of the patient in two or more semi-meridians.
16. The method of claim 10 , further comprising:
selecting the distance of the second zone to the center of the central zone to generate different amounts of pincushion distortion or barrel distortion in the eye of the patient in two or more semi-meridians.
