Abstract: Eyeglass assemblies include an eyeglass lens having an engaging portion. The junction between the body portion of the lens and the engaging portion can consist essentially of smoothly curved surfaces. The engaging portion can be extend from the periphery of the lens or can be a recess in the lens. In some assemblies, under typical conditions of use, the engaging portion is maintained in contact with an eyeglass frame member by means of a removable bonding member (RBM). Under selected atypical ambient conditions, the RBM changes so that the engaging portion and the frame member can be separated. The RBM can be a suitable adhesive (RBA), or a component composed of a shape memory metal (RBSMA) or a material which softens when subjected to heat or other atypical condition.

Abstract: Eyewear includes a frame front (14) having first and second sides (26, 28) to which are attached respective first and second temple arms (40, 42). The frame front is pivotally coupled to the temple arms to provide multiple tilt adjustment positions that enable a person wearing the eyewear to rotate the frame front about a pivot axis (48) between forward-facing and near-field adjustment positions (52, 56). First and second nose pad arms (70l, 70r) couple respective first and second nose pads (72l, 72r) to the frame front and have respective first and second nose bridge-contacting surfaces (74l, 74r). The nose pad arms extend from the frame front in a direction that sets an offset distance (92) between the nose bridge-contacting surfaces and the frame front to establish a vertical drop distance (98) that allows the user rotating the frame front about the pivot axis to the near-field adjustment position to see over the top long side (86) of the frame front.

Abstract: In an OCT system, the autocorrelation signal depends only on the strength of the signal in the object arm scattered back from a patient's retina and is a result of different reflections from different layers of the retina interfering with each other. The strength of the autocorrelation signal depends on how well focused the system is. Normally the autocorrelation signal is treated as noise. However by removing the reference path signal, the autocorrelation signal is easily measured and analyzed. The optimal focus can the then be found by adjusting the focus value until the autocorrelation signal is maximized.
