Definitions

  • the invention falls within the field of Optometry and Ophthalmology, specifically in the determination of peripheral vision and peripheral visual anticipation in people.

Perimetry determines the visual boundaries in its contour. A greater decrease in visual acuity is perceived in the temporal retina area.
  • the peripheral visual field outside the central 30 degrees, is approximately five times larger in surface than the central field and this will require a considerably long examination time in order to analyze it.
  • Visual field confrontation test it is a basic and rapid review of the visual field in which the examiner sits directly in front of the person examined, 50 cm at eye level. The examinee will cover one eye and stare into the opposite eye of the examiner with the other. A stimulus is placed where the examinee cannot see it and slowly moves towards their line of sight. You will be asked to say when you can see that stimulus. Later it is repeated with the other eye.
  • REPLACEMENT SHEET (Rule 26) A target in the center. You are asked to stare at the object in the center and let the examiner know when you can see an object that is moving towards your lateral vision. This test creates a map of your complete peripheral vision.

  • Peripheral vision is considered crucial in team sports and there are several studies that report a superior development of the visual field in players who play sports. Even within these players, there are differences between those who have more experience (the expert uses peripheral vision while the inexperienced uses the central vision) and differences between players who play as a team (higher level of peripheral vision) or at the individual level.
  • the stimulus moves slowly from the periphery of the visual field to the point of sight fixation.
  • the reaction time to the stimuli received in the periphery is longer than to those captured in the central region, but the visual panorama is wider and the perception is executed earlier, which compensates for the delay of the reaction.
  • peripheral vision varies in the same subject according to the chromatic characteristics of the stimulus. That is, players with white or red shirts will not be captured in the same way on the pitch and even then, they will react to them faster than if they were playing with blue, black or purple shirts.
  • the athlete perceives the moving object before discriminating the color in question.
  • peripheral visual field is evaluated with limited equipment in space, at distances within a dome, where the stimuli to be used in the measurement are located, with lighting problems and therefore must be performed in a dark room, avoiding the reflections on the surface perceived by the person examined.

  • Each bar has on the front side two rows of seven lights each: one of LED (Light Emitting Diode) of white color (1) at the top and another of RGB LEDs (Red, Green, Blue) three-color (2), Red, blue and green, at the bottom.

  • the examinee will have to be able to perceive the visual stimulus, in this case a light from the row on, indicating the precise moment in which it is perceived.

Abstract

L'invention concerne un dispositif en forme de barre et un système de mesure cinétique de la vision périphérique et de l'anticipation visuelle périphérique. La solution consiste à déterminer le moment où apparaît le stimulus visuel dans le champ de vision périphérique et dans l'estimation de l'apparition de celui-ci en un point déterminé, tout en enregistrant s'il y a anticipation ou retard, par utilisation de deux barres égales et symétriques dans lesquelles sont allumées des lignes de lumières DEL de différentes couleurs suivant un ordre déterminé. Le système de l'invention résout le problème résidant dans le fait de déterminer les deux mesures dans des situations les plus proches de la réalité du travail ou du jeu avec des éclairages similaires à ceux du milieu.
