An adjustable vision test device for ophthalmology treatment

Abstract

The invention discloses an adjustable vision testing device for ophthalmological treatment. The adjustable vision testing device structurally comprises an adjusting cross bar, a suspended main pole, an automatic opening and closing protecting cover, a level adjustor, an interpupillary distance window, an interpupillary distance adjusting rotary knob, a fixed chassis, an adjusting movable disc, a sphere turning wheel, a rotary disc, a prism, a cross concave-cylinder, a sight hole, circumocular rubber rings and a concave-cylinder turning wheel, wherein the suspending main pole is arranged at theleft end of the adjusting cross bar and is connected vertically to the adjusting cross bar through electrowelding; and the automatic opening and closing protecting cover is arranged above the level adjustor at the middle lower end of the suspended main pole. The device has the beneficial effects that the automatic opening and closing protecting cover is arranged to protect parts such as the prismand the cross concave-cylinder of the device and prevent the device from being exposed and worn, dust can be prevented, the cleaning efficiency of the device is reduced, and the burden of ophthalmological medical staff is alleviated; meanwhile, the service life of the vision testing device is prolonged, and the device has the automatic opening and closing function, is convenient to operate and improves the automatic degree effectively.
