Abstract: A ring device is adapted for wearing on at least one finger of a user. The ring device includes a wearable main body portion and an optical member that is moveably affixed thereto. The optical member can be positioned in at least two positions: a viewing position, and a storage position. The optical member may be moved relative to the main body portion through a number of positioning mechanisms including: a hinged member, a sliding member, and a rotating member. The viewing position may include any number positions for viewing an object in a field of view. The storage position corresponds to an alignment of the optical member with the main body such that the device is aesthetically pleasing.

Abstract: A spatial light modulator has a modulating unit, a refracting part, and a flat part. The modulating unit includes a matrix of pixels, and a light-shielding portion between each of the pixels. The refracting part is a prism group composed of prism elements, each having at least a refracting surface. The modulated light from one of the pixels is incident on at least a portion of the prism group. The refracting surface is oriented to project an image of the pixel over an image of the light-shielding portion on a screen at a predetermined distance, making an apex with an angle with respect to a reference surface that is orthogonal to an optical axis at the apex. A distance d between the reference surface and the flat part satisfies d<0.95×?/(2×(n?1)) or d>1.05×?/(2×(n?1)), ? being a wavelength of the light, and n being a refractive index of the prism elements.

The outer edge of the lens retaining member is removably engaged with the frame.

The primary spectacles includes two lenses, a primary bridge extended between two inner sides of the lenses respectively. The detachable shelter frame includes two shelter lenses, a shelter bridge extended between two inner sides of the shelter lenses, and a mounting arrangement comprising first through second supporting members spacedly and rearwardly extended from the shelter bridge to engage on the primary bridge so as to support the detachable shelter frame with at least two point supports.

Abstract: There is described an apparatus and a fixture used in determining position and for producing assembling holes in a spectacle lens for rimless spectacles. The assembling holes are intended for receiving a U-shaped bracket which is used in fastening bridge and side bar hinge. The apparatus and fixture includes interacting guide pins and guide holes. These guide holes/pins are unambiguously disposed. The guide holes will preferably be placed symmetrically in relation to a hole center line for the lens, when this is placed in the fixation opening of the fixture with the hole center line disposed opposite to markings at the fixation opening. The assembling holes are thus placed symmetrically in relation to the marking. By such a system it is possible to make rimless spectacles that appear very accurate, without special skilled qualifications on the part of the optician to make assembling holes in the lenses.

Abstract: Methods, devices, and systems establish an optical surface shape that mitigates or treats a vision condition in a patient. An optical surface shape for a particular patient can be determined using a set of patient parameters for the specific patient by using a compound modulation transfer function (CMTF). The compound modulation transfer function can include a combination of modulation transfer functions (MTF's) at a plurality of distinct frequencies.

Abstract: This invention pertains to an attachment for bifocal eyeglasses which is a dynamic frame fitted with the lens for intermediate vision which will lie in front of the middle one third of the bifocal lens during computer use providing three zones of vision at a time without changing the head position or changing to a separate computer eye glass. This attachment along with the bifocal eye glass enables the optical centers of the distant vision and intermediate vision lens to overlap with each other falling on the visual axis, coinciding with the pupillary center of the eye at the primary head position overcoming strain, distortions and aberrations. This dynamic frame is locked at the side of the main frame with the help of press locks when ‘not in use’. This invention makes long hours of computer work comfortable and helps to overcome computer vision syndrome.

Abstract: A bridge structure for glasses and nose pad thereof is disclosed. The bridge structure for glasses includes a connecting portion and two nose pads. The connecting portion has a joint hole and a clipping portion. Each of the two nose pads has an anti-sliding structure, a ventilating notch, and a plurality of rib-shaped members. The joint hole and the clipping portion are used to fix the bridge structure on the glasses. The anti-sliding structure prevents the glasses from sliding off the wearer's nose due to sweat. The ventilating notch helps dissipate heat and evaporate sweat. The rib-shaped members gently contact the user's nose and increase comfort during wear.

Abstract: Eye refraction is measured to achieve desired quality via a selected vision characteristics. A characteristic of vision is selected to correlate to the desired quality of vision from a group of vision characteristics comprising acuity, Strehl ratio, contrast sensitivity, night vision, day vision, and depth of focus, dynamic refraction over a period of time during focus accommodation, and dynamic refraction over a period of time during pupil constriction and dilation. Wavefront aberration measurements are used to objectively measure the state of the eye refraction that defines the desired vision characteristic. The measured state of refraction is expressed with a mathematical function enabling correction of the pre-selected vision characteristic to achieve the desired quality of vision. The mathematical expression function may be a Zernike polynomial having both second order and higher order terms or a function determined by spline mathematical calculations.

Abstract: In a method for testing the visual field of a patient especially the central visual field, stereoscopic or binocularly displaced fixation images are presented under computer control to the respective eyes of the patient. In addition, a series of test images viewable by only one of the patient's eyes is generated under the control of the computer. The fixation images, one for each eye, are presented on two separate electronic displays, while the test images may be produced on a third display member different from the electronic displays. The computer is programmed to precisely determine a boundary between points corresponding to unseen test images and points corresponding to seen test images, by automatically testing additional points in a region located about the curve and between points corresponding to unseen test images and points corresponding to seen test images.

Abstract: A fastening mechanism for fastening eyewear, such as spectacles or clip-on lenses, to clothing has a first and second clips pivotally connected by a pivot. The first clip has jaws is for gripping the eyewear on extremities of pivotally connected respective first and second jaws thereof. The second clip has jaws is for gripping the clothing on extremities of pivotally connected respective first and second jaws thereof. The pivot connects the first lever of the first clip to one of the levers of the second clip, and is situated generally longitudinally opposite the extremities of the first clip, thereby permitting the clips to be freely pivoted relative one another by gravity to suspend the jaws of the first clip, and thereby the eyewear, below the pivot. The jaws of the first clip have cushions which abuttingly contact the eyewear when gripped by the jaws of the first clip.
