The yellowing of eye beads can be caused by physiological factors, liver and gallbladder system diseases, blepharospasm and other factors. 1. Physiological factors: with ageing, body aging, metabolic function decreases, the eye surface can occur pigmentation and other changes, which is manifested as yellowing of the eyeballs. 1. Liver and gallbladder diseases: yellowing of eyeballs can indicate liver and gallbladder diseases. When liver and gallbladder diseases occur and obstructive jaundice occurs, it can lead to yellow staining of eyeballs and skin of the whole body, etc. It is feasible to take liver function tests and other tests to observe total bilirubin, direct bilirubin, indirect bilirubin and other indexes, so as to clarify the condition. 2. Blepharospasmosis: yellowing of eye beads can also occur when blepharospasmosis occurs, usually located in the blepharospasm and other parts of the eyelid, mainly due to the long-term stimulation of the exposed part of the eye surface by the external environment, resulting in localized degenerative changes of the lid conjunctiva and other causes. If the yellowing of the eyes is obvious and accompanied by discomfort, it is recommended to consult a doctor in a timely manner, under the guidance of a specialized doctor to actively carry out appropriate treatment, which will help to alleviate the discomfort as soon as possible.
