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.
