If the symptoms disappear in a black environment, this is a physiological phenomenon, mainly due to vitreous liquefaction or posterior vitreous detachment, which does not affect vision and therefore usually does not require treatment. It is recommended not to pay too much attention to it in general, as the symptoms will actually become more pronounced the more you pay attention to them. Of course, if you feel that it is really obvious and affects your normal life, you can also consider taking oral lecithin complex iodine tablets, or performing laser ablation to improve the symptoms.
