发明名称 ADJUSTABLE MAGNIFYING APPARATUS AND METHOD FOR VIEWING VIDEO OR COMPUTER SCREENS
摘要 The present invention is directed to an optical device and method for adjustably magnifying the visual displays on the screen of a computer monitor or the like, the invention comprising an adjustable arm for supporting at least one magnifying lens in front of the monitor, which adjustable arm is attached to a stationary support independent of an operator's body. The adjustable arm for supporting the magnifying lens between the viewer of the screen and the screen of the computer monitor is movable in a substantially axial and vertical direction with respect to the computer screen, so that the magnifying lens can be adjustably positioning to a desired position relative to said screen. The invention is especially useful for helping presbyopic computer operators to more clearly see the visual displays on the screen. A second embodiment of the invention further comprises a second lens that can be used to view a document held next to the monitor.
