Definitions

  • the invention relates to smart eyeglasses, and, in particular, it relates to anti-myopia training eyeglasses.
  • Myopia is inability to see things properly when they are far away. Such an eye condition not only brings inconvenience for people's life but also poses significant costs for optical correction and potential treatment for associated cataract and glaucoma in the longer term.
  • myopia has increased dramatically, especially in some highly educated groups. In parallel with the increase in overall myopia, there has been a rise in the prevalence of high myopia. Furthermore, myopia is appearing with greater prevalence in young children, which places these children at greater risk of developing high myopia, with its associated complications.
  • the document DE10217344A1 proposes an eye treatment device, which dynamically displays an object or figure on a screen in such a way that it is sometimes blurred and sometimes sharp, bringing the object virtually close to a patient and then far away, in a rhythmic manner.
  • WO2014/174067A1 proposes a method of using a head mounted electro-optical device according to visual parameters of a wearer.
  • a head mounted device can be used as a pair of multifocal eye glasses which has a first visual zone for far vision and a second zone for near vision, and can be adapted according to the visual parameters of the wearer.
  • a visual signal is given to reminder the wearer to glaze through the correct visual zone. By this means it may help slow myopic progress.
  • the present invention intends to suggest a new approach to train the eyesight of the wearer of smart glasses, so as to mitigate visual fatigue and prevent from worth myopia.
  • the present invention aims to provide a device which facilitates preventing myopia or at least alleviating the development of myopia without disturbing the user's routine activity or bringing much burden for the user, especially without expending much time specifically for the eye treatment.
  • a visualizing unit configured for projecting at least one image at a focus spot for the view of a wearer of the eyeglasses
  • a processing unit configured for controlling the eyeglasses to allow the wearer of the eyeglasses to focus on an object that the wearer is looking at in a natural mode.
  • the processing unit is further configured for controlling the visualizing unit to project at least one image on at least one different focus point , so as to attract the view of the wearer of the eyeglasses away from the object and focus nearby or farther away onto the projected image in a training mode.
  • Bifocal head-up display systems have been developed, e.g. mentioned in US2014/0036374A1, in which a projector is used to project images onto two image planes of different distances from a vehicle operator.
  • the similar projection principle can be used for the smart eyeglasses of the invention.
  • the eyeglasses do not project a distracting image to distract the wearer so that the wearer can act as usual, such as reading, writing, watching screen and so on.
  • the eyeglasses can operate to project at least one image, e.g., still pictures or video, to distract the wearer's eyes to focus nearby or farther away than in the natural mode. For example, when a wearer is reading a book or viewing a screen, an image is projected at a farther focus point in the wearer's vision range in the training mode.
  • the distracting image is easy to be noticed by the wearer and may guide the wearer's eyes to focus farther away.
  • the focus point of the wearer's eyes has to change over time under the direction of the eyeglasses, so that the eye activity as playing outdoors is simulated during the wearer's usual indoor activity, without requiring the wearer to spend specific time only for eye treatment.
  • the visualizing unit can be controlled to project images on different focus points, e.g. on a close by focus point and a focus point farther away.
  • the eyeglasses are not only an eye exercising device but also a display which may replace the typical screen of a device such as smart phone, e-reader, PC and so on.
  • the processing unit is configured for detecting a first time period for which the wearer of the eyeglasses has been looking at the object in the natural mode, and switching the eyeglasses from the natural mode to the training mode when the detected first time period exceeds a first threshold.
  • the processing unit is configured for detecting a second time period for which the wearer of the eyeglasses has been looking at said at least one image projected by the visualizing unit in the training mode, and switching from the training mode back to the natural mode when the detected second time period exceeds a second threshold.
  • the eyeglasses may direct the user to perform the eye exercises periodically.

  • the switching of the two modes may be controlled more precisely.
  • light retroreflected from eyes of the wearer can be captured by an inward- facing camera integrated in the eyeglasses when the wearer's eyesight is looking at an object, so as to create a retroreflected image, which can be focused onto an image sensor, and the focus distance of the eyes of the wearer can be determined by means of processing the focused image.
