Method for determining the dominant eye

A method is provided for determining the dominant eye of a person using equipment designed to acquire at least one image of the face of the person, then process the image, and finally return information enabling the person to know which eye is the dominant eye thereof. The method uses a sighting device that is identifiable and locatable in relation to the equipment, with the viewing being carried out through a window with both eyes open. The size of the window is such that it does not allow the person to see said target with both eyes at the same time. The equipment acquires at least one image for viewing the position of both eyes of the person, processing the image by performing calculations while taking into account the position of a central point located between both eyes, the position of the target and the position of the window.
