Improved wearable optics is disclosed. The wearable optics comprises a frame member and a lens. The wearable optics also includes circuitry within the frame member for enhancing the use of the wearable optics. A system and method in accordance with the present invention is directed to a variety of ways to enhance the use of eyeglasses. They are: (1) media focals, that is, utilizing the wearable optics for its intended purpose and enhancing that use by using imaging techniques to improve the vision of the user; (2) telecommunications enhancements that allow the eyeglasses to be integrated with telecommunication devices such as cell phones or the like; and (3) entertainment enhancements that allow the wearable optics to be integrated with devices such as MP3 players, radios, or the like.

The present disclosure provides generally for a particle guard system and apparatus. The system may comprise temples, shield, and nose bridge. A particle guard may prevent or limit aspiration from entering the user's external environment via shield that covers the nose and mouth. The particle guard may comprise interchangeable components for personalization and various utility. The temples and the nose bridge may be available in various colors and styles for customization of the particle guard. The particle guard may possess attachments for various utility. Temples may comprise integrated attachments. For example, temples may contain a wireless signal device for external communication. The particle guard may comprise a sanitation system. Where the system includes external covering, shield may interface with the external covering via opening in the external covering.

An air-fed visor comprises a mask, at least part of which comprises a foam material. An air tube is provided for delivering air to the visor. An air distribution rose is disposed in the foam mask. The rose comprises an air inlet connected to the air tube and an air distribution chamber for distributing air from the air inlet into the foam material.

Systems and methods of the present disclosure are directed to neural stimulation via audio and visual stimulations. The combination and/or sequence of audio and visual brain stimulations can adjust, control or otherwise manage the frequency of the neural oscillations to provide beneficial effects to one or more cognitive states or cognitive functions of the brain, while mitigating or preventing adverse consequences on a cognitive state or cognitive function that stems from sleep deprivation. In doing so, the present systems and methods can reduce sleep fragmentation, improve sleep quality, and slow the progression of cognitive decline in a subject with Alzheimer's disease and MCI.

An improved system and method for an eye patch can comprise a patch and a pad. The patch can be substantially flat and flexible. Furthermore, the patch can comprise a bottom surface, a top surface, and a concave edge. The bottom surface can comprise an adhesive capable of temporarily attaching to a skin. The concave edge can be on one side of the patch. Additionally, the concave edge can substantially match the anatomical curve of a human's eye socket. The pad can be a raised portion on the patch that can be capable of pushing upper natural eyelashes upward when a client closes her eyes. The pad can be attachable along the concave edge.

A dry eye treatment device and method including a pliable thermal pack engageable upon a first side of a vibration ring is provided. The vibration ring has a second side adapted for positioning on the face of a user to communicate vibration to the eyelids of a user from the vibration ring, and heat or cold from a bulging portion of the thermal pack communicating through a pair of openings in the vibration ring. A cover forming a cavity on the face of the user to house the vibration ring and the thermal pack may also be employed.
