Not at all, using your eyes does not make them worse. In fact, quite the opposite is true. However, you must use them in healthy conditions. That means that when reading or working at the computer, we must have a good posture and prevent our eyes from drying out as we tend to blink less and there is increased evaporation of tears when staring at something for a long time. To clarify further, don't stop reading or doing any visual activities if you have glaucoma.
