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.

An apparatus to treat, inhibit, or prevent an indication of a headache symptom in a patient can include a cover, sized and shaped to fit over an eye of the patient to define a cavity between the cover and an anterior surface of the eye when the cover is located over the patient eye. The apparatus can include a pressure source, in communication with the cavity, capable of applying non-ambient cavity pressure to the cavity. The apparatus can include control circuitry, in communication with the pressure source, the control circuitry storing or otherwise configured to define a target cavity pressure value specified to treat, inhibit, or prevent the headache symptom, and configured to control the pressure source to adjust the cavity pressure toward the target cavity pressure value to treat, inhibit, or prevent the headache symptom.

Methods and systems for assessing and/or treating visual disorders, such as discorder in accommodative ability and/or vergence ability, of a person are provided. Assessment and training exercises can be performed utilizing a computerized system in communication with a head-mountable display (HMD), such as a virtual or augmented reality display, which can display visual targets at various vergence and accommodative demands. Lenses, such as inverted bifocal lenses, may be used in combination with the HMD to mimic natural accommodative demand during viewing or to enable assessment and treatment of accommodation disorders. Corrective factors can be calculated and utilized for generation of visual targets to account for lens characteristics and/or interpupillary distance mismatch. Accommodation and vergence responses can be tracked during display of the visual targets at the various demands, and assessed in comparison to normalized values for assessment of vision disorders or utilized to track progress of user in treatment of a vision disorder.

An apparatus includes a training area in the form of an enclosed space in which light levels can be controlled, at least one physical element related to a task for which an individual is to be trained, and a lighting arrangement. The lighting arrangement generates a background luminance level in the training area sufficient to cause the vision system of the individual to function in the mesopic or low photopic range of vision, and the physical elements are themselves illuminated by an illumination means. The luminance level of the physical elements is greater than the background luminance level.
