  • Patent number: 12239375
    Abstract: Methods and apparatus for producing images of the retina or fundus with improved quality and visualization of its features. This is accomplished by adjustment of specific pupil size, pupil position, detector pinhole size and wavelength parameters of the instrument to give improved image quality as described by a chosen image quality metric. Methods are less complex than adaptive optics and give an improved image in a region of interest and potentially over a larger field of view. Thus, it will be useful in instruments designed for the screening of retinal disease(s). The methodology is applicable to an individual's eye, on the basis of either the group that said individual falls into or measurements of the quality of their eye's optics. As described herein, the settings (including optimum pupil size, pupil position, detector pinhole size and/or wavelength for imaging) can be chosen to give improved the retinal image quality.

  • Patent number: 12228801
    Abstract: Eyewear hinge assemblies for eyewear that connect temples to a frame. The hinge assemblies include hinge elements that are attached to the temples in an extended state, which stores an initial amount of energy or pre-load. The pre-load biases the temples inwardly and toward one another. After the temples are placed on the user's head, stored energy in the hinge elements can be released as the hinge elements exhibit elastic recoil. This causes the temples to grip the sides of the user's head in a snug and comfortable fit. The hinge assemblies have compact designs with material properties that provide comfortable closing forces while aiding in the reduction of electromagnetic noise from electrical subsystems in the eyewear.
