Q: My eyes hurt after using my desktop computer for only a couple of hours. Should I get a bigger monitor? A: That might help, but there are a couple of more common causes of achy eyes related to computer usage. Insufficient blinking is a normal tendency when staring at screens, and that can cause dryness and irritation. Another problem is poorly focused vision, especially if you’re old enough to need reading glasses. Time for a checkup!
