An apparatus for screening, treatment, monitoring and/or assessment of visual impairments, comprising electronic means for simultaneously applying two separate and unrelated processing methods to images presented to a patient's eyes; a first processing method being applied to an non-amblyopic eye (the eye with the better vision), and a second processing method being applied to an amblyopic eye (the weaker eye, or the impaired eye). A method for screening, treatment, monitoring and/or assessment of visual impairments, comprising: a. defining a starting point, wherein differences between a patient's eyes are completely, or as closely as practically possible, corrected, to enable two identical or similar images to be transferred to the brain from the patient's eyes; b. defining an ending point, wherein there is no correction applied to any of the patient's eyes; c. defining a screening, treatment, monitoring and/or assessment plan, for initially applying correction to images according to the starting point, then gradually reducing the correction, at a controlled and predetermined rate, towards the ending point; and d. applying the plan to images presented to the patient's eyes, while monitoring patient's performance.

In accordance with one aspect of the present invention, an optical coherence tomography-based ophthalmic testing center system includes an optical coherence tomography instrument comprising an eyepiece for receiving at least one eye of a user or subject; a light source that outputs light that is directed through the eyepiece into the user's or subject's eye, an interferometer configured to produce optical interference using light reflected from the user's/subject's eye, an optical detector disposed so as to detect said optical interference; and a processing unit coupled to the detector. The ophthalmic testing center system can be configured to perform a multitude of self-administered functional and/or structural ophthalmic tests and output the test data

A binocular scanning laser ophthalmoscope (SLO) is used to track the fixational eye movement of each of the eyes of a subject. The binocular SLO may include right eye optics for imaging a portion of the retina of the right eye and left eye optics for imaging a portion of the retina of the left eye. Shifts in the imaged portion of the retina with respect to a reference image of the retina may be used to measure and track eye movement. The right eye optics and left eye optics may be separate imaging paths, each with its own bi-directional MEMS scanning mirror and Keplerian telescope. The use of the MEMS scanning mirrors minimizes the size and weight of the binocular SLO.

A system and method for measuring and treating vergence disorders may include an augmented reality headset connected to a computing device for simultaneously presenting target images independently to a patient's eyes and independently tracking the position of each eye. The headset includes eye tracking technology for monitoring the orientation of the eyes. If the eyes are both on target, as determined by the eye tracking technology, then binocular single vision will occur, and if not, then diplopia will occur. A vergence demand may be created by incrementally moving the target images apart or together, until the vergence demand is too great for the patient to maintain SBV. Amplitudes of fusional vergence may be measured and stored by the computing device. The system may be utilized to perform therapeutic vergence treatment exercises to increase amplitudes of fusional vergence and measure and provide treatment for phoria and strabismus conditions.

A vision inspection and correction method, which mainly uses an image adjustment software/device to separate the eyes of the inspected person on an independent display screen, and the visual mark seen by the same vision is designed to be misaligned; through the guidance and interaction of the inspector and the inspected person, the inspector can adjust the image operation to zoom in/out/shift/focus/diverge/rotate, etc., so that the inspected person's binocular images can be clearly distinguished and adjusted. Then, the binocular images are aligned, and the inspector will implant the correction parameters during the image adjustment process into 3D projectors, VR (virtual reality), AR (augmented reality device), MR hybrid reality device and other equipment to adjust the binocular digital image parameters, thus the users can enjoy personalized adjustment and comfortable images of both eyes, or provide them to lens makers, based on this, create lenses that can make the inspected person's eyes see clearly aligned images.

The present invention discloses a technique for alerting on vision impairment. The system comprises a processing unit configured and operable for receiving scene data being indicative of a scene of at least one consumer in an environment, identifying in the scene data a certain consumer, identifying an event being indicative of a behavioral compensation for vision impairment, and, upon identification of such an event, sending a notification relating to the vision impairment.

[Object] To provide an eye examination attachment, a control device, and an ophthalmic microscope system, by which an image of an eye to be examined that is suitable for observation can be provided. [Solving Means] An eye examination attachment according to the present technology includes a joining unit, a front optical system, and a communication unit. The joining unit is capable of being joined to an ophthalmic microscope. The front optical system includes a front lens capable of being placed in front of an eye to be examined. The communication unit sends information regarding the front optical system to an external device.

A visual perception function evaluation system 10 includes: a display device 12 configured to three-dimensionally display a three-dimensional test image 20 including an object 22 to a subject; a processing device 13 connected to the display device 12; and an input device 11 through which a reply related to whether the object 22 can be perceived is input from the subject to the processing device 13. The processing device 13 includes a display control means 15 for controlling the state of display of the test image 20 on the display device 12, and a neglect region specifying means 16 for specifying a neglect region in a three-dimensional space based on the reply.
