The conditions which put a strain on the eyes can be sitting in front of the computer or television for too long, playing video games, or, reading in improper lighting conditions. But apart from these, a poor posture, stress, and long periods of concentration are also causes for headaches.

Eyestrain means different things to different people. It can be experienced as burning, tightness, sharp pains, dull pains, watering, blurring, double vision, headaches, and other sensations, depending on the person. If you have any eye discomfort caused by viewing something, you can call it eyestrain.
