A system includes glasses for executing a process to correct the alignment of an eye if a misalignment condition is detected. The glasses include lens that change opacity as instructed by a processor. The system determines that an eye is not aligned correctly based on data captured by one or more sensors in the glasses. Data is captured periodically and compared to a baseline set of data. If a deviation is detected, then the appropriate lens is turned “ON” to shade the aligned eye, thereby forcing the misaligned eye to properly align itself.

One embodiment is directed to a system comprising a head-mounted member removably coupleable to the user's head; one or more electromagnetic radiation emitters coupled to the head-mounted member and configured to emit light with at least two different wavelengths toward at least one of the eyes of the user; one or more electromagnetic radiation detectors coupled to the head-mounted member and configured to receive light reflected after encountering at least one blood vessel of the eye; and a controller operatively coupled to the one or more electromagnetic radiation emitters and detectors and configured to cause the one or more electromagnetic radiation emitters to emit pulses of light while also causing the one or more electromagnetic radiation detectors to detect levels of light absorption related to the emitted pulses of light, and to produce an output that is proportional to an oxygen saturation level in the blood vessel.

The invention provides methods and kits for detecting, screening, quantifying or localizing the etiology for reduced or impaired cranial nerve function or conduction; localizing a central nervous system lesion; detecting, diagnosing or screening for increased intracranial pressure, pressure or disruption of central nervous system physiology as seen with concussion; or detecting, diagnosing, monitoring progression of or screening for a disease or condition featuring increased intracranial pressure or concussion by tracking eye movement of the subject. The invention also provides methods and kits useful for detecting, screening for or quantitating disconjugate gaze or strabismus, useful for diagnosing a disease characterized by disconjugate gaze or strabismus in a subject, useful for detecting, monitoring progression of or screening for a disease or condition characterized by disconjugate gaze or strabismus in a subject or useful for quantitating the extent of disconjugate gaze or strabismus. Further, the invention provides methods for assessing or quantifying structural and non-structural traumatic brain injury or diagnosing a disease characterized by or featuring structural and non-structural traumatic brain injury.

Examples of assessing vergence capability of an individual are described. In an example, a first random dot stereogram is generated. The first random dot stereogram includes a first random arrangement of dots and a first sub-portion positioned against the first random dot stereogram. Thereafter, an input from an individual, identifying the position of the first sub-portion against the first random dot stereogram may be received. In response to receiving the input, a second random dot stereogram comprising a second sub-portion positioned against the second random dot stereogram, is generated. The second random dot stereogram comprises a second random arrangement which is different from the first random arrangement of dots in the preceding first random dot stereogram. In response to the second random dot stereogram, another input to identify position of the second sub-portion against the second random dot stereogram is received.

The present invention generally relates to apparatus, software and methods for assessing ocular, ophthalmic, neurological, physiological, psychological and/or behavioral conditions. As disclosed herein, the conditions are assessed using eye-tracking technology that beneficially eliminates the need for a subject to fixate and maintain focus during testing or to produce a secondary (non-optical) physical movement or audible response, i.e., feedback. The subject is only required to look at a series of individual visual stimuli, which is generally an involuntary reaction. The reduced need for cognitive and/or physical involvement of a subject allows the present modalities to achieve greater accuracy, due to reduced human error, and to be used with a wide variety of subjects, including small children, patients with physical disabilities or injuries, patients with diminished mental capacity, elderly patients, animals, etc.

A system and a method are presented, configured for use in data display. The method comprising: providing data about vision requirement of a user, providing data about content to be displayed to the user and generating and displaying initial display data on a display device, and identifying a region of interest of the user within the display data. The method further comprising processing the display data in accordance with the data about vision requirements of the user for generating refreshed and modified display data comprising suitable image processing for at least a portion of the display data within the region of interest and transmitting the refreshed display data to be displayed on the display device. The refreshed and corrected display data thus provides improved image display to the user within the region of interest.
