Why do my eyes feel dry all day?

Your eyes usually feel dry all day because your tears aren’t covering the eye well enough or they’re evaporating too fast.

Common reasons:

• Screen time: You blink less at phones, computers, and TVs, so tears dry out.
• Blocked oil glands: The eyelids make an oily layer that slows evaporation. If those glands clog, eyes can feel dry even if they water.
• Dry air: Heating, air conditioning, fans, and wind strip moisture from the eye surface.
• Medicines: Antihistamines, decongestants, blood pressure meds, and some antidepressants can reduce tears.
• Contact lenses: Long wear can irritate the tear film.
• Age/hormones: Tear production often drops with age, especially after menopause.

Quick help:

• Use the 20-20-20 rule and blink fully.
• Try preservative-free artificial tears.
• Drink enough water and avoid strong airflow toward your face.
