Dry eye syndrome may occur when the eyes fail to produce sufficient tears or when tears evaporate too quickly. Common causes include exposure to wind and sunlight outdoors, prolonged screen time, eye fatigue from extended reading or writing, as well as exposure to smoking environments. Other potential causes are as follows:

1.Taking certain medications, such as antihistamines and some antidepressants.
2.Wearing contact lenses for an excessively long period at a time.
3.Undergoing certain ophthalmic surgeries, such as Laser-Assisted in Situ Keratomileusis (LASIK)
4.Suffering from certain eye conditions, including blepharitis, meibomian gland dysfunction, and allergic conjunctivitis.
