摘要:
Eyeglasses for enhancing visual contrast through the use of hetero-chromic filters are provided. One lens of the glasses is tinted pale green while the other lens is tinted to be a slightly darker yellow. The resulting pair of glasses, when worn, creates color-retinal rivalry between the two eyes to encourage better visual contrast and provide improved vision quality, especially at night. Such hetero-chromic filtration may also be effectively embodied within contact lenses, whether hard, gas-permeable or hydrophilic soft lenses, by incorporating an appropriate dye into each contact lens that is both benign and non-irritating to the eye tissues.

An apparatus for preparing a plastic eyeglass lens includes a coating unit and a lens curing unit. The apparatus is preferably configured to allow the operation of both the coating unit and the lens curing unit. The apparatus may also include a post-cure unit and a controller. The controller is configured to control the operation of the coating unit, the lens curing unit and the post-cure unit. The lens forming unit may include an LCD filter disposed between activating light sources and a mold assembly. The mold assembly preferably includes two mold members held together by a gasket. The gasket preferably includes four protrusions spaced at 90 degree intervals about the gasket. A lens forming composition may include a first photochromic compound, a second photochromic compound and a light effector. The light effector may alter the color of a lens when exposed to photochromic activating light, when compared to a lens formed from a lens forming composition which does not include a light effector.

A lens for eyeglasses is provided with two or more optical zones on the lens body having different optical properties that enhance visualization of different scenes, including target objects within the scenes, that are associated with a specific recreational activity such as golf, hunting, or fishing. A first optical zone in an upper portion of the lens can be provided with pre-defined focus distance, transmission percentage, and/or transmission spectrum parameters for enhanced visualization of distant scenes associated with the specific recreational activity. A second optical zone in a lower or outer portion of the lens can be provided with different pre-defined focus distance, transmission percentage, and/or transmission spectrum parameters for enhanced visualization of close-in scenes associated with the specific recreational activity.

A system for imaging eyeglasses having lenses, and obtaining data indicative of the outline of the eyeglasses and designated locations associated with the outline. The system includes a positioning device for placing the eyeglasses. The system further includes a short focal length imaging device for acquiring an image of the eyeglasses. The system further includes a processor and a display configured to calculate an editable outline for each eyepiece of the eyeglasses and display the outline and the image, such that the editable outline can be compared to a respective eyepiece of the image. The processor is further configured to calculate supplemental locations linked to the outline for manufacturing holes and/or slots that anchor clip-on parts that include bridge and legs, and for providing data indicative of the specified outline and supplemental locations.
摘要:
An optical lens including an optically clear lens element; and a light absorbing coating on a surface of the lens that attenuates transmitted light; has a coloured or colourless reflection as seen from the front of the sunglass lens; and is anti-reflective as seen from the eye side of the lens.
摘要:
An object of the present invention is to provide a polarization optical article comprising a polarizer incorporated therein which provides views through sunglasses, goggles, lenses, or the like with colors close to natural colors by correcting a color hue with substantially grayish coloring. A polarization optical article according to the present invention has a multilayer structure including one polarizer sheet layer, and a colorant correcting the color hue specific to the polarizer sheet is blended or added into at least one of the layers in the structure, so that the optical article is rendered substantially grayish. The optical article comprises a composite sheet consisting of a plurality of sheets including one layer of a polarizer sheet and at least one layer of sheet other than the polarizor sheet which are bonded with each other by an adhesive or a pressure-sensitive adhesive, and a colorant correcting color hue specific to the polarizer sheet is blended into at least one of the polarizer sheet, the sheet other than the polarizor sheet, and the adhesive or pressure-sensitive adhesive layer.
摘要:
A vision directing goggle for directing a batter's vision during batting practice. The vision directing goggle includes a housing for directing the vision of a user. The housing is generally rectangular and has an open top side and an open bottom side. The housing has a first pair of opposing walls and a second pair of opposing walls. An elastomeric strap binds the housing to a user's head. A coupling means couples the strap member to the housing. The coupling means is affixed to an outside surface of each of the second opposing walls.

A method for mounting safety shields onto eyeglass temples and a kit for carrying out that method. A temple of an eyeglass frame is placed in a channel forming part of a side shield thereafter, a screw is inserted into an opening formed in the side shield and into a member affixed to the temple to create a fastened fit between the temple and the channel which attaches the side shield to the temple. The side shield is placed in its operative position before the screw is inserted into the opening and the fastened fit results from the insertion of the screw into the opening and member which holds the side shield in its operative position. The kit includes a side shield having a longitudinally extending channel into which a longitudinally extending eyeglass temple may be inserted. The channel has an open lateral end through which the temple may be inserted and a supporting lateral end against which the temple may be supported. The side shield further includes an opening extending transversely to both the longitudinal direction and the supporting lateral wall. A screw is adapted to be inserted into the opening and the member so as to force the temple against the supporting end of the channel to create a fastened fit between the side shield and the temple when the temple is located in the channel. Alternatively, a fastener is placed into the transverse open lateral end in the channel of the side shield, to receive a screw which is a adapted to be inserted into the fastener to create a fastened fit and prevent the temple from moving longitudinally within the channel of the side shield.
