LENS EXAMINATION EQUIPMENT AND METHOD
Document Type and Number:
WIPO Patent Application WO/2018/073576
Kind Code:
A3
Abstract:
A system (101) for examining lenses in a pair of glasses includes a tablet computer (112), a camera (128) mounted above the computer screen and a glasses mount (156) for holding a lens in a pair of glasses between the camera and the display screen. The camera (128) is operatively connected to the computer for storing and processing image data captured by the camera. In use, a test pattern is displayed on the screen below the camera and an image of the test pattern seen through a lens is captured by the camera. Image data is saved to the computer which processes the data to determine the power of the lens from the distortion to the test pattern caused by the lens. The results are displayed on another section of display screen. The camera mount (156) may be a plinth slidably positioned on the display screen.
