Dryness is rarely caused by one thing. It is usually a combination of how much tear film you produce, how quickly it evaporates, and how often you blink completely.
Common contributors
Long screen sessions reduce blink rate. Dry indoor air, air travel, and fans or vents increase evaporation. Contact lens wear can change how the tear film behaves across the day.
Persistent symptoms deserve an in-person evaluation — there are many causes, and some need specific treatment.
