binocular balance check

In binocular vision, there are actually many kinds of balance, which are roughly optical balance, balance of vision, image balance, balance adjustment, balance of movement and so on. In the binocular visual examination, only the rational use of the balance of both eyes can effectively solve various binocular vision problems and achieve the best optician effect. The polarized optotypes are slightly different depending on the projector. There are two horizontally polarized optotypes, the first row of polarization axes is 135 degrees (or 45 degrees), and the next row is 45 degrees (or 135 degrees). Some have a row of unpolarized optotypes in the two polarization optotypes, a total of three rows. Basic Information Specialist Category: Ophthalmic Examination Category: Applicable gender: whether men and women apply fasting: not fasting Tips: Maintain a normal diet and schedule. Normal value When the images of both eyes pass through the refractive system or the corrected refractive system, they are imaged in the fovea of ​​the macula, at which point both eyes have the same vision. The size, shape, sharpness, contrast, and orientation of the images imaged by the same object on the left and right eye retinas are the same, and the same adjustment is produced when observing objects of the same distance, and the ability of both eyes to follow the target is the same. Clinical significance Abnormal results: When one of the balances is broken, it may affect the normal binocular vision, and the larger the gap, the greater the impact until the binocular vision function is completely lost. Need to check the crowd's binocular astigmatism or single light. Precautions Contraindications before the examination: dripping drops of medicine. Inspection requirements: The inspector must see the target in both eyes. Inspection process When one of the balances is broken, it may affect the normal binocular vision, and the larger the gap, the greater the impact until the binocular vision function is completely lost. Not suitable for the crowd Inappropriate people: those with normal vision.
