干眼是一种多因素导致的慢性眼表疾病，如果得了干眼，首先要尽可能纠正各种引起干眼的不良习惯，定期进行眼健康体检，在专业医生的指导下进行正规治疗。

1. hyperblinking 

Blinking is a protective nerve reflex action, and the tear layer allows tears to be evenly applied to the surface of the cornea and conjunctiva to keep them moist without drying out. In order to facilitate the excretion of lipids from the meibomian gland, you can usually do more blinking training, and blink 10 to 20 times per minute.
