A method and an apparatus for capturing a visual field of a person having a scotoma, in particular a central scotoma, are disclosed. The method includes continuously capturing the eye alignment of the person with a capturing unit, sampling the visual field of the person point-by-point to determine points suitable and not suitable for sight in the visual field of the person, finding the scotoma as a region with a multiplicity of points not suitable for sight, calculating an outer boundary line of the scotoma, calculating an outer enveloping curve, which surrounds the outer boundary line of the scotoma at a predetermined distance, and displaying the outer enveloping curve on a display unit. The enveloping curve is perceivable by the person on the display unit as a frame of the scotoma.

A technique for driving emmetropization of an eye includes receiving image data corresponding to a color image; blurring a first color channel of the image data greater than a second color channel of the image data in at least a portion of the color image to provide a simulated longitudinal chromatic aberration (LCA) in the portion of the color image; and displaying the color image with the simulated LCA to provide an emmetropization therapy to the eye.

A device for treating dry eye syndrome and strengthening eyesight, of the present invention, comprises: a water goggles main body part into which a saline solution is injected, and which is closely adhered to the facial surface of a user, thereby allowing muscular exercise of the eyeballs to be carried out in the saline solution; a saline solution container coupled to the upper part of the water goggles main body part so as to supply a predetermined amount of saline solution; and a display device fixed to the front of the saline solution container, and in which an ocular muscle strengthening program for guiding the user's line of vision is executed so as to enable eyeball exercise to be performed in the saline solution.

A vision protection method is provided to ensure a viewer to rest his/her eyes after viewing on an electronic device for a certain period, wherein the eyesight protection method includes the steps of detecting at least one of eye activities of the viewer and working parameter of the electronic device in a working mode of the electronic device during the viewer is working on a current work displaying by the electronic device; switching the working mode of the electronic device to a resting mode when an abnormal eye activity of the viewer is detected; and switching the electronic device from the resting mode back to the working mode to resume the display of the current work of the electronic device. Therefore, the viewer is enforced to rest his/her eyes after every certain period.

Active dichoptic perceptual-learning tasks or dichoptic game play have been shown to significantly improve visual acuity of amblyopic children and adults. However, these dichoptic perceptual learning tasks are intensive and repetitive such that non-compliance is high. In contrast, the invention provides dichoptic perceptual learning in a manner that the user maintains its use and compliance is increased. Further, compliance becomes automatic if the user performs tasks in a normal manner and “forgets” that they are actually undergoing treatment as it is integrated with minimal disruption to their life and activities. Accordingly, a methodology exploiting complementary dichoptic stimulation is presented.

An intelligent intraocular and extraocular muscle sensitivity exercise training instrument which is disposed with an ocular head (1) consisting of a front shell (11), a middle shell (12) and a back shell (13), and a control device (2) electrically connected to the ocular head (1), as well as an intraocular muscle exercise bar (3) electrically connected to the control device (2). The beneficial effects are as below: in addition to supplementing the field of portable intraocular and extraocular muscle training instruments, it is also convenient for students to put it in their school bags for use at any time thanks to its intelligent operations and foldable structure, it overcomes the shortcomings of the above-mentioned pure extraocular and intraocular muscle sensitivity training instruments. Therefore, it is bound to have a profound effect on myopia control, dyslexia remediation, eye healthcare, and memory improvement among teenagers.
