Why did you suddenly get dry eyes?

Sudden dry eye disease is caused by insufficient lacrimal secretion, excessive tear evaporation, abnormal tear composition, etc.

1. Insufficient lacrimal secretion The

disease generally reduces tear secretion with age, which leads to dry eye disease.

2. Excessive tear evaporation

If the patient is exposed to wind, dry air, smoking, or reading for a long time, driving, or using electronic products, it may cause excessive tear evaporation and cause disease.

3. Abnormal tear composition

If the patient has meibomian gland blockage, it may cause abnormal lipid secretion, resulting in dry eye disease.
