What is Visual Fatigue?

Visual fatigue refers to the strain and tiredness experienced by the eyes, often resulting from prolonged periods of viewing, especially under conditions that require intense concentration, such as driving. When a driver experiences visual fatigue, they may notice that objects appear blurry, and their ability to maintain clear focus diminishes. This decline in visual acuity can significantly impair their ability to recognize details on the road, such as traffic signs, pedestrians, and other vehicles, which heightens the risk of accidents.

Maintaining clear vision is critical for safe driving, as a distracted or unfocused driver is less capable of responding appropriately to changes in the driving environment. Therefore, understanding visual fatigue helps drivers recognize the importance of taking breaks during long journeys or when they begin to feel signs of fatigue.
