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 after covering and uncovering the at least one of the subject's eyes. 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.
