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.

The invention relates to a thermal skin treatment device comprising a skin contact component with a skin contact surface; a thermal energy component in thermal contact with the skin contact component; a temperature control circuit electrically connected to the thermal energy component and comprising a user interface; and an energy source electrically connected to said thermal energy component for energy supply. Said temperature control circuit is adapted to control an amount of energy supplied from said energy source to said thermal energy component such that a first predetermined temperature is maintained at the skin contact surface for a first duration, or a second predetermined temperature is maintained at the skin contact surface for a second duration, wherein said first predetermined temperature is in a range of 40° C.+/−2° C., and wherein said second predetermined temperature is in a range of 19° C.+/−2° C. The temperature control circuit is adapted to maintain for a predetermined duration, during operation, only said first predetermined temperature or said second predetermined temperature at the skin contact surface. The invention further relates to a method for non-therapeutic treatment of a human eye region by means of a thermal skin treatment device according to the invention.

The visual function test device of an embodiment comprises a test subject display device and an operator display device. A target display portion displays a target image to be viewed by the test subject onto the test subject display device. A visual axis estimation portion estimates a visual axis of the test subject when the target image is viewed. A position display portion displays a display position of the test target image and a viewpoint position that corresponds to the estimated visual axis, onto the operator display device, and thus a tester can objectively recognize a gazing state of the test subject and surely perform the test, which enhances the reliability of the test.

Vision-assist devices and methods are disclosed. In one embodiment, a vision-assist device includes an image sensor for generating image data corresponding to a scene, a processor, and an inertia measuring unit. The inertia measuring unit is configured to measure forces acting on the image sensor and the orientation of the image sensor. The processor is configured to receive the image data from the image sensor and process the force and orientation of the image sensor so as to determine a tilt of the image sensor. The processor is further configured to process the image data based on at least the tilt of the at least one image sensor so as to generate a corrected image data, wherein the corrected image data does not include the tilt.

It is an object of the present invention to provide a vision training device having an excellent vision training efficiency as vision training is performed in consideration of a status of personal vision. In order to achieve the above object, a vision training device according to the present invention includes a refractive index-adjustable lens disposed in a field of view direction of an eye of a user and having a refractive index which is changed with supply of an electric current, a lens drive unit including one or more electrodes electrically connected to the refractive index-adjustable lens and a voltage adjusting unit capable of adjusting a voltage applied to the one or more electrodes, and a control unit that that controls the voltage adjusting unit such that a refractive index of the refractive index-adjustable lenses is adjusted, sets at least one training range within a refractive index adjustment range of the refractive index-adjustable lenses, and adjusts the refractive index of the refractive index-adjustable lenses in the training range.

A steam therapy equipment including a vessel for heating a mixture of water and organic materials, a compressor to inject pressurized air into the vessel producing pressurized steam. The pressurized steam is conducted into the equipment via one or more valves. The therapy equipment is formed from at least one panel and may include a supporting frame. The therapy equipment includes a temperature sensor to measure the temperature inside the therapy equipment when pressurized steam is admitted via the valves. A patient enters the equipment and is exposed to the pressurized steam, causing dilation of the skin pores of the patient, whereby toxins are removed from the patient. One or more applicators may conduct pressurized steam to specific portions of the body of the patient. The patient may be provided with a portion of the mixture to consume as part of the steam therapy treatment.

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.
