Dry Eyes More Condition_symptoms Are My Dry Eyes Caused By Something More Then Staring?

Are my dry eyes caused by something more then staring? - dry eyes more condition_symptoms

I was just on the computer, quite literally, all day.
Now that I developed dry eyes.

I've never develop dry eyes when the computer is in the other cases.

I can also be a throat infection. Have dry eye is only a symptom of the disease? Or maybe a mixture?
