There are no eye drops that can treat the problem of double vision, and patients should take the right treatment for their situation. Commonly, there are monocular double vision and binocular double vision, which can be treated with glasses or surgery. 1. Monocular double vision, which may be caused by refractive problems, such as myopia and astigmatism, can be manifested as the phenomenon of false edges and double shadows when looking at things. In this case, we should go to the ophthalmology department of the hospital to have a clear optometry or astigmatism, and wear glasses with appropriate prescription to correct it. 2. Double vision: It may be caused by paralysis of eye muscles or strabismus due to various reasons. Under the doctor’s guidance, some neurotrophic drugs should be used to help restore the function of paralyzed extraocular muscles. If necessary, corrective surgery for strabismus or other surgical treatments are required. If the patient has the problem of double vision, it is recommended not to blindly use medication to treat it, but should go to the hospital in time to have the relevant examination, and then give the correct and standardized treatment according to the examination results.
