Abstract
An example method for automatically measuring a subject's phoria while the subject fixates on a visual target can include capturing an image of at least one of the subject's eyes using an image capturing device. The image can include a reflection of light from at least one of the subject's eyes. The method can also include analyzing the image to identify a position of the reflection of the light within at least one of the subject's eyes, and determining a phoria measurement based on the position of the reflection of the light within at least one of the subject's eyes.
Claims27
A method for automatically measuring a subject's phoria while the subject fixates on a visual target, comprising:
- capturing an image of at least one of the subject's eyes using an image capturing device, the image including a reflection of light from any surface of the at least one of the subject's eyes;
- analyzing the image to identify a position of the reflection of the light within the at least one of the subject's eyes;
- determining a phoria measurement based on the position of the reflection of the light within the at least one of the subject's eyes;
- performing an autorefraction measurement, the autorefraction measurement measuring a power of one of the subject's eyes while focusing on the visual target;
- and
- calculating an accommodative convergence accommodation ratio based on a position of the reflection of the light within at least one of the subject's eyes and the autorefraction measurement.
An apparatus for automatically measuring a subject's phoria while the subject fixates on a visual target, comprising:
- an image capturing device for capturing an image of at least one of the subject's eyes;
- a processor;
- and
- a memory in operable communication with the processor, the memory having computer-executable instructions stored thereon that, when executed by the processor, cause the processor to:
- receive the image from the image capturing device, the image including a reflection of light from any surface of the at least one of the subject's eyes;
- analyze the image to identify a position of the reflection of the light within the at least one of the subject's eyes;
- determine a phoria measurement based on the position of the reflection of the light within the at least one of the subject's eyes;
- perform an autorefraction measurement that measures a power of the one of the subject's eyes while focusing on the visual target;
- and
- calculate an accommodative convergence accommodation ratio based on a position of the reflection of the light within at least one of the subject's eyes and the autorefraction measurement.
