How long it takes for young people to recover from vitreous clouding is mainly related to the type of disease and the individual situation of the patient, and should be analyzed on a case-by-case basis, and should not be generalized. In the case of physiological vitreous clouding in young people, it is mainly due to the gradual liquefaction and clouding of the vitreous during the development of myopia, which may recover on its own after a reasonable diet and proper rest and conditioning. However, the specific time is uncertain, it may be a few months, or it may take several years, and some patients even cannot recover. In the case of pathological vitreous opacity, the primary disease needs to be treated in a timely manner, and vitreous opacity can be recovered after the primary disease is cured. Therefore, the specific time of recovery is related to the time of healing of the primary disease, which in most cases takes several months. In conclusion, it is recommended that young people who develop vitreous clouding should go to the ophthalmology department of a regular hospital in a timely manner, and should not buy their own medication.
