Blue eyes are clinically caused by staying up late. Prolonged late nights and excessive eye use can cause impaired blood circulation around the eyes, and slow venous blood flow can intensify pigmentation and lead to glazing around the eyes, which can be exacerbated by fatty deposits in the eyes as we age. It can also be caused by cardiovascular diseases, such as thrombosis, atherosclerosis, and blood system disorders, resulting in the formation of microthrombi, which are deposited around the eyes with the blood flow movement and can cause the symptoms of eye glazing, which usually takes 1-2 weeks to recover. During the recovery period, you need to avoid staying up late, ensure the quality of sleep and consume sufficient water, which can alleviate the pigmentation phenomenon. Eye examinations can also be performed in the hospital to expel other organic lesions, clarify the cause, and subsequently perform repair surgery to restore the appearance.
