A vision training device includes a housing having at least one eyepiece unit corresponding to an eye of a user, a display that displays a target image in front of a fixation axis of the user, a lens arranged between the eyepiece unit and the display unit, a movable unit capable of moving at least one of the display and the lens along the fixation axis, and a control unit that sets at least one training range within a movable range of the display and the lens and controls the movable unit such that at least one of the display and the lens is moved within the training range.

Exemplary light control devices and methods provide a regional variation of visual information and sampling (“V-VIS”) of an ocular field of view that improves or stabilizes vision, ameliorates a visual symptom, reduces the rate of vision loss, or reduces the progression of an ophthalmic or neurologic condition, disease, injury or disorder. The V-VIS devices and methods generate a moving aperture effect anterior to a retina that samples and delivers to the retina environmental light from an ocular field of view at a sampling rate between 50 hertz and 50 kilohertz. Certain of these V-VIS devices and methods may be combined with augmented or virtual reality, vision measurement, vision monitoring, or other therapies including, but not limited to, pharmacological, gene, retinal replacement and stem cell therapies.

An apparatus to maintain an environment over an anterior surface of a patient eye can include an enclosure sized and shaped to be seated about the patient eye to form a cavity within the enclosure. The enclosure can be configured to contain a fluid other than ambient air in contact with the patient eye. The apparatus can include a fluid regulator in communication with the enclosure, where the fluid regulator can be configured to regulate the composition of the fluid contained within the enclosure.

A system for improving a patient's vision, comprising means for diagnosing and monitoring a deterioration in macular vision or macular vision loss in the patient's eye, and means for augmenting the use of a preferred retinal location (PRL) and eccentric fixation in case the deterioration in macular vision or macular vision loss was detected. A method for improving a patient's vision, comprising: diagnosing and monitoring a deterioration in macular vision or macular vision loss in the patient's eye; and augmenting the use of a preferred retinal location (PRL) and eccentric fixation in case the deterioration in macular vision or macular vision loss was detected.

A headset for ocular dermal therapy is used for one or more of reducing dark eye circles, rejuvenating eyelid skin, boosting micro circulation, enhancing transdermal eye serum adsorption, reduction of allergy related skin conditions around the islands, improving skin tone, eye muscle relaxation and stress relief. The headset has a pair of periorbital contact eye pads which are controlled by a controller to administer ocular dermal therapy to the skin of the eyelids and surrounding the eye.

A method to treat a dry eye condition of an individual, includes: receiving a switch signal generated based on a manipulation of a control switch at a handheld device; and activating a motor in response to the switch signal to oscillate a member at an oscillation frequency, the member having an elongated configuration, and having a portion for placement outside the individual; wherein the oscillation frequency is sufficient to induce tear production when the portion of the member is applied towards a surface of a body portion of the individual.

A system for testing and/or training the vision of a user is disclosed herein. The system includes at least one camera, a visual display device having an output screen, and a data processing device operatively coupled to the at least one camera and the visual display device. In one embodiment, the data processing device is programmed to determine a head position, head velocity, and/or head speed of a user during a vision test or vision training routine from a plurality of images of the head of the user captured by the at least one camera. In another embodiment, the data processing device is programmed to determine, based upon an input signal received from a user input device, a contrast display setting for a screen background relative to at least one visual target, the contrast display setting enabling the user to gradually adapt to increasing levels of visual stimulation.

A vision training device includes a main body, a lens unit, a drive motor, and a controller. The lens unit includes a plurality of lenses respectively having different diopter values and a lens holder that supports the lenses. The drive motor moves the lens holder so that one of the lenses of the lens unit is disposed on a line of sight axis. The controller controls the drive motor such that a test lens selected from the plurality of lenses is disposed on the line of sight axis and stores an accommodation time indicating a period of time in which the eye becomes in an accommodated state to the test lens.
