Systems and methods for determining an angle of repose of an asymmetric lens

A device for determining an angle of repose of a contact lens on an eye, comprising:

• a display;
• a camera with a camera lens, a data processor;
• an orientation sensor and a user input device, and including instructions executable by the data processor to:
• display a view finder image from the camera on the display prior to capturing an image;
• display an orientation graphic on the display using the orientation sensor while displaying the view finder image, the orientation graphic including graphical constructs that indicate orientation of the camera lens around a line of sight axis normal to the camera lens, around a horizontal axis and around a vertical axis;
• store an image captured using the camera;
• execute a graphical user interface using the display, the graphical user interface including a frame or frames including the captured image, and graphical constructs prompting input identifying a set of locations on the captured image usable to define a location of the contact lens in the image, and a location usable to define an angle of repose of the contact lens in the image;
• and
• accept input data responsive to the graphical constructs that identifies the set of locations to define the location of the lens in the captured image and the location to define the angle of response of the contact lens in the captured image.

A computer program product for determining an angle of repose of a contact lens on an eye using a device having a display;

• a camera with a camera lens, a data processor, an orientation sensor and a user input device, the product comprising a non-transitory computer readable medium storing instructions executable by the data processor, the instructions comprising:
• logic to display a view finder image from a camera on the display prior to capturing the image;
• logic to display an orientation graphic on the display while displaying the view finder image, using the orientation sensor, the orientation graphic including graphical constructs that indicate orientation of the camera lens around a line of sight axis normal to the cameral lens, around a horizontal axis and around a vertical axis;
• logic to store an image captured using the camera;
• logic to execute a graphical user interface using the display, the graphical user interface including a frame or frames including the captured image, and graphical constructs prompting input identifying a set of locations on the captured image usable to define a location of the contact lens in the image, and a location usable to define an angle of repose of the contact lens in the image;
• and
• logic to accept input data responsive to the graphical constructs that identifies the set of locations to define the location of the contact lens in the captured image and the location to define the angle of repose of the contact lens in the captured image.
