Stereoscopic vision

Stereoscopic vision is the perception that the scene can distinguish the near and far form of the object. 1 Same-view machine inspection: It can check the binocular vision function, including simultaneous view, fusion image and stereoscopic view function. Stereoscopic images are required to check stereoscopic vision. It can be carried out according to the same machine inspection instructions, and the results are judged. 2 Stereoscopic visual inspection device: consists of three different thickness test panels, each of which is printed with four random network structure patterns, one of which is convex in the middle (concave from the other side). Basic Information Specialist Category: Ophthalmic Examination Category: Other Inspections Applicable gender: whether men and women apply fasting: not fasting Tips: Keep a normal mindset. Normal value If the stereoscopic function of the testee is normal, the pattern can be quickly and correctly found to determine how many seconds the stereoscopic visual acuity is, normally 100S. The advantage of this test is that it does not need to wear extraordinary glasses. It is quickly found out whether the subject has stereoscopic vision. Clinical significance Abnormal results eyeball vibration, strabismus, eye, seeing things blinking, no three-dimensional, poor eye coordination. The stereoscopic vision is missing (stereo blind) in the population that needs to be examined. Precautions Taboo before inspection: If you find this phenomenon, don't delay. Requirements for inspection: Pay attention to the orientation direction. Inspection process Usually available: 1 with the same machine inspection: can check the binocular vision function, including simultaneous view, fusion image, stereoscopic three-level view function. Stereoscopic images are required to check stereoscopic vision. It can be carried out according to the same machine inspection instructions, and the results are judged. 2 Stereoscopic visual inspection device: consists of three different thickness test panels, each of which is printed with four random network structure patterns, one of which is convex in the middle (concave from the other side).
