Abstract: A detection method and a detection system for detecting surface abnormalities of a first lens and a second lens of an optical-electrical lens unit are provided. The first lens and the second lens are respectively protruded from two adjacent surfaces of the optical-electrical lens unit. The detection system includes a first detecting element configured to capture the image of the first lens, a second detecting element configured to capture the image of the second lens, a processing device configured to calculate whether the second lens is not oriented toward the second detecting element, and send moving instructions to a control device to control the optical-electrical lens unit to move to a predetermined position, and detect the surface abnormalities of the optical-electrical lens unit based on the captured images.

Abstract: A method for inspecting lenses, especially wet contact lenses provided in a volume of liquid inside a container is described. A first image of the lens at a first position in the container is obtained, the lens then being moved to a second position within the container where a second image is obtained. A computer algorithm processes the first and second images to compare features that have moved with the lens to those features that have not moved with the lens whereby lenses are rejected if a feature has moved with the lens but is not a normal feature of the lens.

Abstract: A fluid dispenser dispenses a fluid alternately from one of a pair of ports (29,31) that are provided on opposite ends of a syringe (26) by moving a piston (42) back and forth inside the syringe. A pair of stirrers (47,48) are provided in the syringe on opposite axial sides of the piston. The stirrers may each individually rotate on an axis that extends in parallel with the moving direction of the piston. A pair of stirrer driving rings (49,50) are mounted on an outer periphery of the syringe in correspondence with the stirrers. Magnets (55,56,59,60) are embedded in the stirrers and the stirrer driving rings such that the stirrer is rotated by magnetic fields that are generated from the stirrer driving ring, as the stirrer driving ring is rotated by a motor (51,52).

Abstract: A multi-wavelength wavefront system and method for measuring diffractive lenses. A system may include one or more light sources configured to emit a plurality of wavelengths of light for diffraction by a diffractive lens. A light sensor may be configured to receive the light that is diffracted by the diffractive intraocular lens. A processor may be configured to determine one or more of the plurality of wavelengths that have a peak diffraction efficiency for the diffractive intraocular lens based on the light received by the light sensor.
