Telescope for low-vision eccentric gaze examination and training

Abstract

The invention discloses a telescope for low-vision eccentric gaze examination and training, which comprises a trial frame, a first transparent clamping piece and a second transparent clamping piece, a partition plate is fixedly connected to the middle end of the inner surface of the trial frame, and screw rods are movably connected to the left and right sides of the partition plate and the left and right sides of the inner cavity of the trial frame through bearings; the outer side of the screw rod is fixedly connected with an adjusting knob, the outer surface of the screw rod is in threaded connection with a threaded cylinder, and the bottom of the threaded cylinder is fixedly connected with a lens frame. The telescope is provided with the trial frame, the partition plate, the screw rod, the adjusting knob, the sliding groove and the threaded cylinder, the purposes of adjusting the interpupillary distance, the length of the glasses legs and the angle of the nose pad can be achieved, the trial glasses sheets are arranged, the requirements of conventional refraction correction can be met, the single-tube telescope is arranged, the effects of fixing the focal length and magnifying power can be achieved, and a distance calibration ruler is arranged, and can measure the inspection distance and assemble a sighting mark card, and the sighting mark card is arranged, so that the sighting mark card can play a role in eccentric watching inspection and training.

Description

technical field [0001] The invention relates to the technical field of vision training, in particular to a telescope for low vision eccentric fixation inspection and training. Background technique [0002] At present, the commonly used clinical method to evaluate the off-centre fixation point of low-vision patients with non-central fixation is to use a microperimeter for inspection. This microperimeter is expensive, large in size and not portable. Not every medical institution or Rehabilitation institutions can purchase the equipment, and it is not suitable for out-of-home screening. Secondly, the microperimetry has high technical requirements for the operation and diagnosis. Usually, the operators need to undergo special targeted training before they can operate the machine. In view of the above The reason is that, on the one hand, due to the price of the instrument, many medical or rehabilitation institutions cannot purchase a microperimeter, and because of its large size ...

Problems solved by technology

[0002] At present, the commonly used clinical method to evaluate the off-centre fixation point of low-vision patients with non-central fixation is to use a microperimeter for inspection. This microperimeter is expensive, large in size and not portable. Not every medical institution or Rehabilitation institutions can purchase the equipment, and it is not suitable for out-of-home screening. Secondly, the microperimetry has high technical requirements for the operation and diagnosis. Usually, the operators need to undergo special targeted training before they can operate the machine. In view of the above The reason is that, on the one hand, due to the price of the instrument, many medical or rehabilitation institutions cannot purchase a microperimeter, and because of its large size and inportability, it is not suitable for out-of-home screening; on the other hand, due to the particularity of the instrument, many medical or rehabilitation institutions There are no professionals who can operate and use the perimetry, and there is also a lack of professionals who can formulate a personalized rehabilitation training plan based on the results of the microperimeter. In response to the above problems, we have designed a low-vision eccentric fixation inspection and training telescope.
