Abstract

Various embodiments of methods and systems for improving and enhancing vision are disclosed. Adjustable lenses or optical systems may be used to provide adaptive vision modification. In some embodiments, vision modification may be responsive to the current state of the user'"'"'s visual system. Certain embodiments provide correction of the subject'"'"'s near and far vision. Other embodiments provide enhancement of vision beyond the physiological ranges of focal length or magnification.

42. A method of providing adaptive vision modification, comprising the steps of:

a) detecting a time varying image reflected from an eye of a subject;

b) generating an image data set representative of an instance of said time varying image;

c) determining an image quality attribute of said image data set;

d) comparing said image quality attribute to a reference image quality attribute;

e) determining a lens system adjustment as a function of said image quality attribute and said reference image quality attribute; and

f) adjusting a lens system according to said determined lens system adjustment to modify said time varying image.

43. The method of claim 42, wherein said time varying image is a real-time varying image.

44. The method of claim 42, further including repeating steps a) through f) to provide on-going adaptive vision modification.

45. The method of claim 42, wherein comparing said image quality attribute to said reference image quality attribute includes:

a) determining a numerical value corresponding to the image quality attribute; and

b) comparing the determined numerical value to a stored value corresponding to the reference image quality attribute.

46. The method of claim 42, wherein said reference image quality attribute is an image quality attribute of a previous instance of said time varying image.

47. The method of claim 42, wherein said time varying image is detected from a first location in said eye and wherein said reference image quality attribute is an image quality attribute of a time varying image detected from a second location.

48. The method of claim 47, wherein said second location is external to the optics of the eye of the subject.

49. The method of claim 47, wherein said second location is the within the eye of the subject.

50. The method of claim 47, wherein said second location is one of the cornea of the eye of the subject, the front surface of the lens of the eye of the subject, and the back surface of the lens of the eye of the subject.

51. The method of claim 42, wherein determining an image quality attribute is performed using a device including a microprocessor.

52. The method of claim 42, wherein the device including a microprocessor is sized or otherwise configured for being carried or worn by the subject.

53. The method of claim 42, wherein the device including a microprocessor is sized so as to be a component of a pair of eyeglasses.

54. The method of claim 42, further comprising transmitting at least a portion of said image data set wirelessly to a receiving location at a distance farther from the eye of the subject than the lens system.

55. The method of claim 54, wherein the receiving location is remote from the subject.

56. The method of claim 54, wherein the receiving location is at a device carried by the subject.

57. The method of claim 42, including transmitting a control signal from the receiving location to the lens system.

58. The method of claim 57, wherein at least a portion of the control signal is a digital signal.

117. The method of claim 47, wherein said second location is the cornea of the eye of the subject.

118. The method of claim 47, wherein said second location is the front surface of the lens of the eye of the subject.

119. The method of claim 47, wherein said second location is the back surface of the lens of the eye of the subject.
