In front of the eyes, there are floating objects like dots, meshes or strips, which are clinically called vitreous opacity, commonly known as floaters, and can be divided into physiological and pathological vitreous opacity. If there is no visual impairment, it is generally considered to be a physiological floater mosquito disease, and no drug treatment is required. Regular observation is enough. If patients feel that their symptoms are serious, they can also take lecithin complex iodine orally or apply aminoiodopeptide eyedrops locally. If there is obvious vision decline, you need to go to the hospital ophthalmology department for fundus examination to exclude fundus diseases. At ordinary times, pay attention to rest, watch less electronic products, eat low salt and low-fat diet, and eat more fresh vegetables and fruits.
