Eye-related discomfort (asthenopia)

Asthenopia, or eye-related discomfort, describes a visual impairment that triggers physical discomfort such as headaches, dizziness, malaise, blurred vision or reddening of the eyes. The causes of this discomfort must be examined closely. Often, inappropriate glasses, a correction that is too strong or too weak, or overfatigue/overexertion are the cause.
