A face shield adapted to protect the face from biohazards during medical procedures is disclosed. The central portion of the face shield includes a horizontally centered cut out that extends downwardly from a top edge. The cut out is sized and positioned to allow a loupe light to pass through. The central portion of the face shield may be hingedly connected to a pair of side portions. A pair of side portions extends outwardly from respective sides of the central portion. Each of the pair of side portions includes attachment structure, such as a clip, to attach the face shield to the temples of a pair of loupes.

A mud visor formed by a substantially transparent sheet is attached to a goggle lens. The mud visor may be attached to the goggle lens using a substantially transparent adhesive or adhesive tape. Thus, the mud visor may provide clear and improved field of view for the user. Further, the mud visor may be configured to cover and guide a top portion of a roll-off film as the roll-off film is conveyed across the goggle lens. A top portion of the mud visor may be inserted into the lens groove of a goggle frame along with the goggle lens when the goggle lens is attached to the goggle frame. The mud visor also may stretch across the goggle lens and overlap with film canisters at both sides to provide a seamless coverage to prevent mud from entering behind the mud visor or the roll-off film.

An adhesively attached eye mask includes a transparent or semi-transparent plastic eyepiece for positioning over a user's eyes and an integral elongated transparent plastic temple or tab extending rearward from each side edge of the eyepiece for contacting the sides of a user's face. A peripheral edge of the eyepiece can include an adhesive. A face mask can be connected to a lower edge of the eye mask for covering the user's nose and mouth. A peripheral edge of the face mask can include an adhesive. A flexible loop or band can be positioned at each side of the face mask.

A laser eye protection device is described that includes an optically opaque screen that covers both eyes; one or more internal viewing screens on an eye-facing side of the optically opaque screen; and one or more cameras arranged around the optically opaque screen, wherein the one or more cameras are in electrical and data communication with the one or more internal viewing screens and provide a visual representation of surroundings to a user.

An optical system having a spectral transmission profile having an average transmittance Ta between 380 nm and 780 nm and an average red light transmittance Tr between a first limit L1 and a second limit L2, with Tr<2*Ta/3 and L1=600 nm and L2=780 nm, and the optical system being configured to allow selectively retinal exposure of an eye to at least one selected range of wavelengths of light in the visible spectrum of 460 nm to 530 nm.

An assembled full-face mask includes a goggle, an outer lens, and a mask shell. The outer lens includes a sheet and a pivotal frame that is connected to the sheet. The pivotal frame is assembled to the goggle, and the outer lens is rotatable relative to the goggle along a first axis. The mask shell includes two connection rods assembled to the goggle and a shell body that is connected to the two connection rods. The mask shell is rotatable relative to the goggle along a second axis that is parallel to and spaced apart from the first axis. When one of the outer lens and the mask shell is rotated relative to the goggle by a first angle, another one of the outer lens and the mask shell is rotatable relative to the goggle by a second angle that is less than the first angle.

A multi-thickness lens for a goggle may be disclosed in accordance with various embodiments. The multi-thickness lens may include a portion of a first thickness and a portion of a second thickness. In particular, the multi-thickness lens may be inserted into a goggle, including goggles configured to receive standard lenses. Further, the goggle may include features that may allow the multi-thickness lens to distribute forces and/or stresses to the goggle and/or may include features and/or components adapting the goggle to receive a multi-thickness lens.

A facial protection equipment for an easy operation of rotating opening and closing, includes: a facial protection unit of which one side is supported at one side of a face of an operator and which shields and protects at least the one side of the face of the operator; a fixing unit that is worn on a head of the operator; and a connection member of which one end portion is coupled to one side of the fixing unit to be rotatable in an up-down direction and another end portion is coupled to the facial protection unit, where the connection member has a pivot bracket of which one end portion is coupled to the one side of the fixing unit to be rotatable in the up-down direction.

The present invention is a depth sensing visual prosthesis. By depth sensing objects within an image, items located at a certain depths from the user can be removed to declutter an image. The resulting image presents only objects within a range of depth from the visual prosthesis user. Depth sensing can be accomplished in various ways including structured light, time of flight, or preferably, a stereo camera pair.

Active dichoptic perceptual-learning tasks or dichoptic game play have been shown to significantly improve visual acuity of amblyopic children and adults. However, these dichoptic perceptual learning tasks are intensive and repetitive such that non-compliance is high. In contrast, the invention provides dichoptic perceptual learning in a manner that the user maintains its use and compliance is increased. Further, compliance becomes automatic if the user performs tasks in a normal manner and “forgets” that they are actually under-going treatment as it is integrated with minimal disruption to their life and activities. Accordingly, a methodology exploiting complementary dichoptic stimulation is presented.
