A device to stimulate the retina comprises one or more light sources coupled to one or more optical elements. The one or more optical elements is configured to illuminate the retina with one or more images at a location away from a fovea of a wearer. In some embodiments, each of the one or more images comprises a depth of focus and a spatial resolution. The one or more images can be formed at a distance anterior to the retina, at a distance posterior to the retina or on the retina. In some embodiments, the depth of focus is less than the distance, and the spatial resolution greater than a spatial resolution of the retina at the location.

Apparatus and methods for producing narrow-band radiation in the green region of the visible spectrum are described. The narrow-band radiation may be used to aid subjects experiencing photophobia. In some cases, subjects may experience a reduction in pain (e.g., migraine photophobia) when using the narrow-band radiation.

A rejuvenating beauty care tool for skin and body is an apparatus that enables the user to treat different skin and body areas using different therapeutic and cosmetic techniques. The apparatus may include a handle, a first arm, a second arm, a plurality of first rollers, and a plurality of second rollers. The handle enables the user to comfortably operate the apparatus using only one hand. The handle also supports the first arm and the second arm when the first arm and the second arm are pressed against the user's body. The first arm presses the plurality of first rollers against a first target body area. Likewise, the second arm presses the plurality of second rollers against a second target body area. Further, both the plurality of first rollers and the plurality of second rollers enable the application of the desired cosmetic or therapeutic treatment onto the target body areas.

Embodiments of the present disclosure provide systems, apparatuses and methods for synchronous communication and control of LED lights and sensors in an LED light array containing two or more LED lights. Through the use of a master clock within a gateway and/or a master controller that is in communication with LED lights in an array that is in a facility, such as in a greenhouse, hot house, poultry egg production facility, a hospital, dairy production or other lighting facilities, the gateway and/or master controller is capable of synchronizing the emission of light or photons from an LED light array by generating a master signal that contains commands and time from a master clock within the signal that is transmitted to each of the LED lights within an array.

Described herein are methods, devices and systems for stimulating neural oscillations in the high gamma wave frequency, in particular to promote neuronal plasticity and removal of the perineuronal net. Such methods, devices and systems are useful for treating neuropsychiatric disorders such as schizophrenia and depression in a subject in need thereof.

Provided are conformable light delivery devices for increasing light penetration depth and related methods. The device may comprise a microarray of tissue penetrating members, each member having a distal end and a proximal end, wherein the tissue penetrating members are at least partially optically transparent to provide optical transmission through a surface that extends between the distal and proximal ends of each tissue penetrating member and a substrate that supports the tissue penetrating members, wherein the substrate is optionally a flexible substrate.

A device including a semi-rigid shell forming an external surface with at least part of the shell adapted to contact tissue of a body cavity. The shell includes a treatment band formed around the shell, a first portion forming a rounded end of the device that is distal to the treatment band, and a second portion formed around the circumference of the shell and located proximal to the treatment band. The device further includes a vibration mechanism configured to case the shell to vibrate, a sensor configured to provide sensor data upon contact with the tissue, and a processor configured to receive the sensor data and to use the sensor data to produce parameters of the tissue.

The present application discloses a LED therapeutic device comprising a top case, a light assembly, a controller, a switch assembly, a bottom case and a power supply. The light assembly comprises a lens and a LED assembly, wherein the lens is coupled to the top case and the LED assembly comprises three visible light LEDs and two infrared LEDs. Wavelengths of the three visible light LEDs are 470 nm, 630 nm and 660 nm. Wavelengths of the two infrared LEDs are 850 nm and 940 nm. The controller is coupled to the light assembly. The switch assembly is coupled to the controller. The bottom case is removably coupled to the top case. The power supply is electrically coupled to the controller.

The present invention is comprised of a novel solar radiation simulation device that simulates the sun by radiating the same spectrum of wavelengths, with the accompanying power levels, as the sun when the sun projects energy upon the Earth in accordance with the time of the day, year, and location. It will bring “the sun inside.” The device can be controlled manually by an end-user or can include pre-programmed modes that control settings of the device or can be dynamically controlled through the input from solar light meters located around the world. This device improves human health but can also be used as a typical light source and can even function as an entertainment device.

The invention presents methods and devices for controlling and modifying the core body temperature of a human or other mammal. The apparatus contains an element to be placed in contact with an individual's skin, such as the palm of a hand or sole of a foot; the element emits radiation, preferably within the red to infrared range of 550 nm to 950 nm, inducing vasodilation and increased blood flow in the region beneath the contacting area. A heat exchange element is concurrently in contact with the skin, capable of transferring heat into or removing heat from the circulatory vasculature, through the skin surface. The circulatory system carries the increase or decrease in thermal energy to the body's core organs. As such the method and devices are capable of increasing or decreasing the core body temperature, or maintaining current core body temperature in the presence of external thermal elements.
