A protective shield is provided for covering a self-contained breathing apparatus (SCBA) mask or a full- face air purifying respirator (APR) lens to prevent damage and scratching. The shield consists of a die cut shape of thermoplastic sheet that duplicates the outline of the self-contained breathing apparatus mask lens and/or frame. The protective shield can be produced using various grades, colors and/or densities of material replicating limited visibility or blackout conditions. To protect the majority of the plastic lens, the shape of the shield includes a peripheral overlap onto the mask utilizing the SCBA lens frame. The shield can be attached to the self-contained breathing apparatus face mask by means of any of the following: bungee, hook, or elastic cord; all of which allows the shield to be attached or removed quickly. Many SCBA/APR training exercises require limited visibility. The invention can be used as an effective training tool to prevent light transmission and simulate extremely limited visibility.

A facial shield for a protective headgear system includes a polymeric sheet having an upper portion configured to be coupled to a support and a lower portion having a lower extremity, wherein the upper portion includes a first hole, a second hole, and a third hole, each one of the first, second, and third holes laterally spaced from the other two of the first, second, and third holes, and the first hole including a first section having a first hole gap and a second section laterally adjacent the first section and having a second hole gap, wherein the first hole gap of the first hole is greater than or equal to the maximum vertical dimension of a first hook of the support, and wherein the second hole gap of the first hole is greater than a vertical base thickness of a base of the first hook and is less than the maximum vertical dimension of the first hook.

A wearable electronic device may be formed from a layer of fabric having opposing first and second ends. The ends may have first and second respective ear openings that receive a user's ears and may have speakers for playing audio. A soft central portion of the fabric between the ends may overlap the user's eyes. The wearable electronic device may have control circuitry that receives power from a power source. Sensors may be used to gather sensor information such as biometric sensor information. The sensors, control circuitry, and power source may be mounted in a stiff edge portion of the fabric. The stiff edge portion of the fabric may have an elongated strip shape and may extend along an upper edge of the central and the electronic device. Stiffener structures sandwiched between inner and outer layers of the fabric may be used to support speakers.

The eye covering includes an elongated sleeve filled with media, such as beads. The sleeve is divided into separate cells. Preferably two central cells are provided for covering the eyes with two lateral cells provided for covering ears. End structures on the sleeve are configured with a retainer to allow the end structures to be attached together. One form of retainer is a slit in one of the end structures. The other end structure is fed through this slit so that the sleeve is formed into a circuit which can fit around the head. Another optional retainer includes a loop, such as a tag, joined to one of the end structures with a gap beneath the tag. A strap can join lateral edges of the eye covering to provide a sleep mask embodiment.

An apparatus includes multiple first reservoirs and multiple second reservoirs joined with a substrate. Selected ones of the multiple first reservoirs include a reducing agent, and first reservoir surfaces of selected ones of the multiple first reservoirs are proximate to a first substrate surface. Selected ones of the multiple second reservoirs include an oxidizing agent, and second reservoir surfaces of selected ones of the multiple second reservoirs are proximate to the first substrate surface.

A disposable perioperative eye patch for protecting the eyes and eyelashes of anesthetized patients during and immediately after surgery. The perioperative eye patch may be applied to the eyes of an anesthetized patient prior to surgery to securely, yet delicately, keep a patient's eyes closed during surgery to avoid ocular dryness and injury. The perioperative eye patch may be comprised of a dressing, a cushion, and a cover, allowing the perioperative eye patch to be securely attached to a patient's periorbital region. The size of the dressing, as well as the adhesive used, allow the perioperative eye patch to be applied and removed from a patient's periorbital region without causing damage to a patient's eyelashes during the perioperative period.
