The present invention relates to ophthalmic systems comprising a selective light wavelength filter, wherein said selective filter provides improved contrast sensitivity.

High performance selective light wavelength filtering providing improved contrast sensitivity

Some embodiments provide a lens including a lens body and an optical filter configured to attenuate visible light in a plurality of spectral bands. Each of the plurality of spectral bands can include an absorptance peak with a spectral bandwidth, a maximum absorptance, and an integrated absorptance peak area within the spectral bandwidth. An attenuation factor obtained by dividing the integrated absorptance peak area within the spectral bandwidth by the spectral bandwidth of the absorptance peak can be greater than or equal to about 0.8 for the absorptance peak in each of the plurality of spectral bands.

Eyewear with chroma enhancement

Ophthalmic systems are provided that include both a photochromic component and a blue-blocking component.

Photochromic ophthalmic systems that selectively filter specific blue light wavelengths

A helmet mounted display (HMD) system comprising a display pod having a light wave optical element. The display pod is designed to be attached to a base plate located above the brow of a helmet using opposing hook and loop-style fastener pads or alternatively, a pair of locking disks. The mounting position of the display pod is adjustable within three degrees of freedom, including lateral positioning along a plane that is co-planar to a mounting surface for the display pod, as well as rotation about an axis that is perpendicular to the mounting surface. The HMD system is adapted to compensate for variations in mounting position using a bore sighting adjustment.

Apparatus and method for mounting and calibrating a helmet-mounted display

Embodiments of methods, devices and systems are presented for communicating information in an explosive environment. An explosion proof video and data communication module includes features that prevent the generation of a spark or other ignition sources that could ignite explosive dust, gas or vapors in the air. The explosion proof video and communications relay modules may operate independently or as a group to provide real-time information, situation awareness, functionally and responsiveness for personnel that are in explosive environments.

Method and system for providing explosion proof video and communication relay module

An abnormality detection support device, suitable for a case where rescue operations are made under situations that visibility is disturbed by smoke due to fire, includes an infrared camera, a display which, at least when the infrared camera is in use, comes to be positioned in front of a user's eyes and reproduces an image taken by the infrared camera thereon and a face protector or a helmet, on which the infrared camera and the display are provided, and the infrared camera and the display are arranged to be within an outline of the user's head in a front view when the device is put on the user. The present invention can, therefore, provide the abnormality detection support device which enables an operator to work with both hands available while directly watching the infrared image even under a circumstance that smoke or the like due to occurrence of fire disturbs the field of vision of the operator, and has excellent usability.

In a lens for safety glasses of the present invention, a first lens element which shields a laser beam is laid on a second lens element for antiglare. The first and the second lens element may be affixed together. In the lens for safety glasses, the first lens element includes a substrate which contains an absorbent for selectively absorbing a laser beam having a specific wavelength in an ultraviolet wavelength region, a visible light wavelength region or an infrared wavelength legion and is transparent in the visible light wavelength region. The safety glasses with the lens may provide comfortable fit and a good appearance, causes less misjudgment of colors and prevents loss of correct color sense, and has both a laser-beam shielding function and an antiglare function.

Lens for Safety Glasses

PROBLEM TO BE SOLVED: To provide a lens for goggles which has a satisfactory wearing property and excellent appearance, hardly gives rise to deviation in color recognition and chromatic vision and also has a laser beam shielding function and an anti-dazzle function in combination. SOLUTION: The lens for goggles are constituted by superposing a first lens element for shielding a laser beam and a second lens element for anti-dazzling on each other. The lens for the goggles are constituted by sticking the first lens element for shielding the laser beam and the second lens element for anti-dazzling to each other. The first lens element used for the goggles is composed of a base material which contains an absorbent selectively absrbing a specific wavelength in a UV wavelength region, visible ray wavelength region or IR wavelength region, and is transparent in the visible ray wavelength region.

Lens for goggles

PROBLEM TO BE SOLVED: To provide goggles for sports which enable a user to check displayed information at need even during exercising and to relatively rapidly and timely obtain the information judged to be adequate, prevent the athletic ability from degrading in spite of gazing at a display section and enable the user to receive meticulous coaching from an instructor, coach, etc. SOLUTION: The goggles are formed by mounting information processing means 2 on a goggle body 1 and providing an eyepiece section 3 of the goggle body 1 with information display means 4. Information transmission means for transmitting and receiving the information relating to the exercise to and from the outside is mounted on the goggle body 1. Further, the information processing means 2 and the information display means 4 can be formed as an integral unit. COPYRIGHT: (C)2003,JPO

Goggles for sports

PROBLEM TO BE SOLVED: To provide a failure probe supporting device satisfactorily enabling a job site worker to come into action with his (her) both hands while directly looking at an infrared ray image even under such a condition that the worker's view is blocked by the smoke of fire and the like, and excellent in user-friendliness SOLUTION: The failure probe supporting device has the following structure: an infrared ray camera and a display positioned in front of the eyes at least when using the infrared ray camera and running a screen image took with the infrared ray camera are set on a face protector or a helmet The infrared ray camera and the display are arranged in a range of the front view contour when the face protector or the helmet is attached to the head of the worker COPYRIGHT: (C)2004,JPO&NCIPI
