Systems and methods for creating fully custom products from scratch without exclusive use of off-the-shelf or pre-specified components. A system for creating custom products includes a computer communicatively coupled with an image capture device and configured to construct an anatomic model of the user based on captured image data and/or measurement data. The computer provides a configurable product model and enables preview and automatic or user-guided customization of the product model. A display is communicatively coupled with the computer and displays the custom product model superimposed on the anatomic model or image data of the user. The computer is further configured to provide the customized product model to a manufacturer for manufacturing eyewear for the user in accordance with the customized product model.

Disclosed is a method for determining a subject's reference head posture, the method including: a) obtaining a movement or a position of at least one eyelid of the subject while he/she moves his/her head up and down starting from an initial head posture wherein he/she directs his/her gaze towards a predetermined direction, the subject keeping his/her gaze directed towards the predetermined direction during the motion of his/her head; and b) determining the reference head posture as a function of a movement or a position of at least one eyelid of the subject during the motion of his/her head at step a). Further disclosed is a method for measuring a distinctive height associated with a frame of a pair of spectacles worn by the subject, as well as a method for mounting and for verifying the mounting of an ophthalmic lens in a frame of a pair of spectacles.

Disclosed is a method wherein the following steps are performed: a) the subject is placed in a natural posture, in which at least one of the gaze directions of the subject points to a visual target, b) an image capture apparatus is placed between the head of the subject and the visual target, c) the relative posture of the image capture apparatus and head of the subject is adjusted in order for the pupil of the image capture apparatus to be positioned close to the gaze direction of at least one of the eyes of the subject, d) an image of the head of the subject is captured, and e) the at least one geometrico-morphological parameter is deduced from this image.

The local refractive power or the refractive power distribution of a spectacle lens is measured. A first image of a scene having a plurality of structure points and a left and/or a right spectacle lens of a frame front is captured with an image capturing device from a first capture position having an imaging beam path for structure points, which extends through the spectacle lens of the frame front. At least two further images of the scene are captured with the image capturing device from different capture positions, one of which can be identical with the first capture position, without the spectacle lenses of the spectacles or without the frame front containing the spectacle lenses having the structure points imaged in the first image, and the coordinates of the structure points in a coordinate system are calculated from the at least two further images of the scene by image analysis.

A head worn display can be designed with an integrated camera for obtaining an image of a scene, transmitting the obtained image to a processor, modification of the image in substantially real time by the processor, and displaying the modified image on a display device worn by the individual. According to embodiments of the invention various methods are provided for adjusting the position of the displayed video in the horizontal left/right, vertical up/down, and horizontal in/out, and angular up/down dimensions relative to the individual's eyes.

A method for providing a personalized optical system for a wearer wherein the optical system characterizes a spectacle ophthalmic lens comprising the following steps: a) providing a visual performance level (VPL) value of at least one eye of the wearer; b) providing a set of rules linking at least the visual performance level of step a) with at least one optical criterion chosen among one or both of the two following optical criteria groups consisting of central vision optical criterion (CVOC) group and peripheral vision optical criterion (PVOC) group; c) calculating the physical and geometrical parameters of the personalized optical system or selecting the personalized optical system in an optical systems data base comprising a plurality of optical systems, so that to meet the set of rules of step b) according to the visual performance level data provided in step a).

The current invention is a detachable eyeglass frame system that will provide consumers a way to take their single pair of prescription lenses out of their manufacturers frames and place them into another set of the same manufacturer's frames but, of different color and/or style. The eyeglass frame system comprises an eyeglass frame including a front section removably secured to a horizontal bar. The horizontal bar is removably secured along the upper end of the front section by one or more fasteners, such as magnets. By lifting the Removable Horizontal Bar from Frame Rear, lenses easily slide out of their current frames and easily slide into their other frames.

When using a Prep Pad that contains a solution soaked with alcohol, adhesive or patch remover, or any other kind of antibacterial agent, the act of operating it while trivial for one time use can quickly become inefficient, mundane and time consuming. The invention packs multiple, but single use encapsulated Pellets inside a cylindrical refill apparatus. The Pellet is made of soft material and it may be soaked or un-soaked. The refill apparatus is then inserted into a cylindrical pen like structure that automatically peels the Pellet when operated. The result is that in a few pen like clicks, an operator, using a single hand, can quickly get ready to cleanse or apply a Pellet onto a surface. An operator can easily store capacity for multiple applications in a pen pocket. The single hand use, quickness to readiness and compact easy storage makes the invention ideal alternative to a Prep Pad like use.

The invention relates to a method for estimating a reference posture of a subject with a view to taking measurements in order to determine the parameters for manufacturing a vision correction device, including, for a plurality of instances in which the head reaches a target reference posture from at least one deviated posture, the steps of: measuring the actual reference posture to thus obtain a plurality of sets of actual reference posture data, and storing said sets of data in a memory; and processing said sets of actual reference posture data using a digital processing unit in order to obtain an optimal reference posture.

A rewritable and freezable lens and method for manufacturing thereof are disclosed. This lens includes at least one active element that has optical properties that can be written, frozen and rewritten into new values at least twice. Rewritable and freezable lenses comprising active index polymer dispersed liquid crystal materials are disclosed. In-situ re-adaptation of spectacle and contact lenses is possible at the point of sale. In-vivo re-adaptation of intraocular lenses in the doctor's room is feasible, avoiding further surgery.
