What describes digital eye strain?

Digital eye strain, also known as computer vision syndrome, refers to the discomfort experienced after prolonged use of screens such as computers, tablets, or smartphones. This condition can manifest as symptoms such as dry eyes, blurred vision, headaches, and fatigue due to factors like screen glare, improper lighting, and poor posture.

The correct answer highlights that digital eye strain arises specifically from the act of screen use, making it distinct from other conditions that might pertain to eye care. In contrast, the other options describe unrelated issues: the need for contact lenses is not directly associated with digital eye strain, nor does the condition improve with increased screen time. Additionally, symptoms of eye infections involve different causes and typically want medical attention rather than being linked to screen use.
