Processing a set of images is disclosed, including: determining a set of user head measurements from a set of images; and determining a fit score corresponding to a glasses frames based at least in part on comparing the set of user head measurements to glasses frame measurements associated with the glasses frames.

Provided is an aqueous ophthalmic solution comprising diquafosol or a salt thereof at a concentration of 0.1% to 10% (w/v) and a chlorhexidine at a concentration of 0.0001% to 0.1% (w/v).

This invention discloses a handheld apparatus for measuring surface power or radius of prescription ophthalmic spectacle lenses, optical lenses or molds blocked with or without chuck during Rx production, and after comparing measurement results with designed data, providing correction data to the processing machines via wireless connection for correction processing if needed. The handheld apparatus integrates an optical measurement head into a monolithic optical system.

A pair of swimming goggles includes a frame having a first sub-frame and a second sub-frame. The first and the second sub-frames have a first opening and a second opening defined therein. A first lens is secured in the first sub-frame and a second lens is secured in the second sub-frame. A first eye-piece and a second eye-piece are arranged adjacent to the first sub-frame and the second sub-frame, respectively. A third lens is secured in the first eye-piece and a fourth lens is secured in the second eye-piece. A first connecting member and a second connecting member releasably secure the first eye-piece and the second eye-piece to the first and the second sub-frames, respectively. At least one of the third and the fourth lens may take the form of a corrective lens.

A portable eyewear electronic device that includes a speaker module and methods of assembly of the device are presented. The electronic eyewear device includes a speaker module that emits acoustic radiation that is channeled through a carrier contained within a temple to one or more acoustic ports near a user's ear.

A lens shield with a principal panel and subpanels having hook and loop closures. The lens shield comprises pockets for coolin devices and a base to stabilize it on a surface.

Eyewear for releasably receiving a lens has a joint sleeve for holding the lens in place.

An apparatus for determining optical parameters of a user with spectacles arranged in the use position on the head of the user includes at least one projection device designed and arranged for marking a partial region of the head of the user and/or of the spectacles of the user with a light projection; at least one image recording device designed and arranged for generating image data at least from the marked partial region of the head of the user and/or of the spectacles of the user; and a data processing device with a user data determining device, which is designed to determine user data from the marked partial region of the head and/or of the spectacles on the basis of the generated image data, wherein the user data comprise spatial information in the three-dimensional space of points of the partial region of the head and/or of the spectacles, and a parameter determining device, which is designed to determine optical parameters of the user on the basis of the user data.
