A head stabilizer device includes a hood having a front, a back, an interior surface, an exterior surface, and a perimeter edge extending between the interior surface and the exterior surface. The interior surface is concave. A tail is elongated having a first end coupled to the back of the hood wherein the tail extends downwardly from the back of the hood. The tail has a length for extending between a seat and buttocks of the person such that the tail is taut extending from the seat to the head such that an upper front section of the perimeter edge of the hood extends across the head of the person to inhibit the head from tilting forward.

A warming device including a heat generating element and an enclosing material that houses the heat generating element is described. A portion of the enclosing material that comes into contact with a target to be warmed when the warming device is in use is made of an air permeable fibrous sheet that contains crimped fibers and non-crimped fibers. The ratio of the non-crimped fibers relative to the total of the crimped fibers and the non-crimped fibers in the fibrous sheet is 50 mass % or more. The fibrous sheet included in the heat generating element is configured to increase the thickness thereof by 0.2 mm or more and 0.7 mm or less during a period from the start to the end of heat generation.

Systems and methods of treating meibomian and sebaceous gland dysfunction. The methods include reducing oxygen concentration in the environment of one or more dysfunctional meibomian and sebaceous glands, thereby restoring a hypoxic status of one or more dysfunctional meibomian and sebaceous glands. The reducing of the oxygen concentration is accomplished by restricting blood flow to the one or more dysfunctional meibomian and sebaceous glands and the environment of one or more dysfunctional meibomian sebaceous glands. The restricting of the blood flow is accomplished by contracting or closing one or more blood vessels around the one or more dysfunctional meibomian or sebaceous glands. The methods also include giving local or systemic drugs that lead to the generation of hypoxia-inducible factors in one or more dysfunctional meibomian and sebaceous glands.

The invention is directed to an eye cover for maintaining eye closure during sleep or for daytime wear for certain eye conditions. The eye cover is sized and shaped so as to fit within the orbit of the patient's eye rather than around the orbit. By fitting closely within the orbit of the eye, the eye cover is much less likely to be disturbed or dislodged during movement over the course of a night's sleep. The eye cover further is porous and includes fenestrations to provide for the passage of air to the eye.

A visor that can be removably attached to a variety of field masks, including those used in softball and baseball and other sports, to protect the user from weather elements and minimize sun damage while not affecting play and withstanding movement. In some embodiments, the visor may include a curvilinear base having at least one recess. The visor may additionally include a brim attached to, or formed with, the base. The visor may further include a fastener received in the at least one recess, where the fastener is configured to secure the visor to the field mask.

Aspects of the present disclosure provide a smart relaxation mask configured to output a stimulus and collect biometric information while the stimulus is output to determine if the subject is paying attention to the stimulus. If the subject is not focused on the stimulus, the mask adjusts at least one of an audio, visual, or haptic output. The stimulus is adjusted in an effort to shift the subject's attention to the stimulus and away from racing thoughts.
