Definitions

  • the present invention relates to the technical field of electronics, mechanics and optometry, since it provides an automated device for testing visual acuity.
  • Optometry is the area of medicine in charge of visual health, where the activities that are carried out range from prevention, diagnosis, treatment and correction of refractive, accommodative, muscular defects and diseases of the anterior segment, in addition to the. design, calculation, adaptation and control of contact lenses and ophthalmic lenses (glasses).
  • Optometry is a health profession that is autonomous, educated and regulated (with a bachelor's degree and registration number), and optometrists are the primary care professionals of eye health and the visual system, which provide comprehensive eye and vision care, which includes refraction and dispensing, detection / diagnosis and treatment of the disease in the eye, and the rehabilitation of visual system conditions '',
  • the identification of the irregularities of the fundus depends on the observation of the changes in the red reflex seen in the pupil.
  • His original ophthalmoscope consisted of a flat glass plate; a light source was located next to the eye to be observed and the plate in front of it, in an oblique direction, so that a fraction of the light is reflected in the area of the plaque towards the eye.
  • the observer could perceive a few, from the background rays, when seeing through the transparent plate, and thus be able to get a background image that was illuminated.
  • the lighting was weak, since only a small part of the light was reflected on the surface of the plate. Then Von Helmholtz increased the amount of light that was reflected by superimposing three flat plates.
  • Loring explains the first monocular ophthalmoscope, whose main feature was that he had greater flexibility in the choice of lenses that allowed him to observe the fundus.
  • This instrument that Loring designed is considered at first as a direct ophthalmoscope, but then added a converging lens so it began to be used as indirect.
  • a technical patent search for an automated device was performed to perform visual acuity tests, where it was found that different systems have been developed for this purpose, as mentioned in the publication of patent number US9173565B2, with publication date of November 3, 2015, and entitled "Automated apparatus and method for vision testing", which describes a vision detection kiosk self-service that allows people to examine their vision without help.
  • the device includes subjective and / or objective tests through an interactive video and a software program that measures visual acuity and contrast sensitivity.
  • the Kiosk is designed to provide a report with the test results.
  • the device and method can also provide a means to make referrals, schedule appointments, order lenses, dispense lenses and / or send prescriptions to eye professionals or lens manufacturers.
  • the aforementioned document refers to a visual testing system without the assistance of a specialist, but this document makes no mention of being a portable device, which in turn lacks being a device that can be operated by means of a smartphone or any mobile device which is connected by bluetooth protocols. It can also be observed that said document does not refer to being a device independent of an energy source, so it cannot be transferred without having construction supplies and specific supplies, so its installation and adaptation cost is high .

Abstract

La présente invention concerne un appareil automatisé pour effectuer des tests d'acuité visuelle, lequel présente la caractéristique d'être portable, léger et de faible coût comparé à ceux existants sur le marché, et comme il n'est pas nécessaire de le connecter à une source d'énergie fixe, il a l'avantage d'effectuer des tests d'acuité visuelle pratiquement n'importe où. Un autre des avantages de l'appareil automatisé pour effectuer des tests d'acuité visuelle est que la commande et l'exploitation se font au moyen d'un dispositif mobile à technologie Bluetooth, ce qui permet de diminuer les temps d'exploitation de celui-ci, diminuant par conséquent le coût de chaque test, et en même temps un plus grand nombre de tests visuels peut être obtenu auprès de différents individus, ce qui fait baisser en même temps les coûts d'exploitation.
