Abstract: An eyeglass frame with replaceable lenses comprises an eyeglass frame with a pair of upper support sides and associated insertion recesses and a pair of lenses with associated insertion portions for engaging the insertion recesses. Two temples are pivotally connected to the two lateral sides of the eyeglass frame, each having a front hole for retaining a corresponding block piece. Each of the lenses further includes a notch on the exterior side of the lens under its insertion portion that can be engaged with a corresponding block projection and locked by a corresponding block flange on a corresponding block piece. Therefore, the lenses will be stably mounted on the eyeglass frame. To dissemble the eyeglasses form the eyeglass frame, the temples are folded so that the block pieces are separated from the front holes. The block pieces are pressed, and then the lenses are pushed outward.

Abstract: An optical characteristic of an eye is obtained which can not be measured through a uniform adjustment because of a large difference in the distribution of a refractive index, or the like. An arithmetic part first selects an interlock mode, and performs an alignment adjustment. Next, the arithmetic part measures refraction, and interlocks and moves a first illumination optical system and a first light receiving optical system on the basis of the refraction. The arithmetic part obtains a density distribution of point images obtained from a first light receiving part, and judges whether a measurement can be made for each area on the basis of the density. The arithmetic part makes an adjustment so that an unmeasurable area becomes measurable, and creates a composite point image from plural signals obtained in a process of the adjustment. Further, the arithmetic part uses the composite point image to perform a Zernike analysis, obtains the optical characteristic and outputs it on a display part or the like.

Abstract: Eyeglasses with lenses changeable include an elongate frame, a nose pad supporter, a lens set and two nose pads. The frame is provided with a lengthwise fitting groove for an upper lengthwise side edge of the lens set to fit therein so that the lens set may be combined removably with the frame. Then different lens sets may be assembled with or disassembled from the frame for changing lens sets if wanted. The assembling or disassembling of the lens set with the frame is effected by engagement of a protrusion formed on an engage block and an engage hole with a notch formed in the lens set. The engage block is formed integral with the nose pad supporter, which is formed integral with the frame. So the lens set is easily assembled with or disassembled from the frame.

Abstract: There is provided an ophthalmologic image pickup apparatus in which a pattern of an image resulting from unnecessary reflected light generated in an optical system by illumination of an illumination unit is stored in a storage unit and the image resulting from the unnecessary reflected light is eliminated using a correction pattern in accordance with an image pickup condition.

Abstract: Glasses adapted to be mounted on caps having an interior band such that terminal temple connecting portions are mounted on such band at two circumferentially-spaced positions, and the glasses so mounted are further adapted to upwardly pivot such that the glasses are easily utilized with caps worn in both the brim rearward and forward positions.

Abstract: A wearable audio interface includes a support for positioning the plurality of speakers juxtaposed to and spaced from the ears of a wearer. The audio device can include wireless networking electronics so as to allow the device to interact with other wireless network devices.

Abstract: A hearing protection device readily insertable and removable from temple arms of eye glasses of varying size, width, angles and flanges, comprising a stiff but bendable vinyl tube, a connector cord, and an earplug. The tube is positioned around the temple bar of glasses past where the temple bar comes into contact with the user's ear when the glasses are worn. The device is held in position by pressure points of contact between the internal surface of the tube and points along the arm of glasses. Once mounted, and glasses worn, the sensation of the vinyl tube simulates the eyeglass arms themselves, and the earplug is conveniently positioned behind and outside of the user's line of vision. The earplug may be inserted and removed from the user's ears as desired given changing noise levels in the user's environment.

Abstract: A brow bar and lens assembly for eyeglasses is provided wherein a flexible brow bar member is attached to a lens assembly only along a central region. By attaching the lens and brow bar in this manner, the brow bar is allowed to flex relative to the lens thereby providing additional means for adjusting the width of the eyeglasses and increasing the comfort for the wearer. Further, the lens construction may include channels along its top edge thereby creating voids that provide a space into which the two ends of the brow bar can travel when deflected relative to the central region.
