The recovery of disparity in vision in both eyes is determined by the cause of the disparity. Usually, disparity in vision between two eyes is caused by refractive errors such as myopia and hyperopia, as well as organic pathologies such as keratitis, cataracts, and fundus disease. If the problem is refractive error, the vision of both eyes can be restored to a relatively consistent state by wearing frame glasses or contact lenses of the right prescription after accurate optometry, or by laser surgery if qualified. In case of organic lesions, medication or surgery is needed to restore the vision according to the specific conditions of the original disease, such as keratitis, which can be treated with antibiotic and antibacterial eye drops, and cataract, which can be treated by medication or surgery such as ultrasound emulsification and IOL implantation. If you have a disparity in vision between the two eyes, you should go to the ophthalmology department and choose to examine the fundus and ultrasound of the eye according to the cause, so as to clarify the cause and treat the problem.
