Fatigue
Fatigue can cause red eye due to the lack of sleep or prolonged use of digital devices. When you’re tired, your eyes can become dry and irritated, leading to redness and inflammation.
Irritation
Irritation from chemicals, smoke, or other environmental factors can cause red eye. When the eyes are exposed to an irritant, the conjunctiva can become inflamed, leading to redness and inflammation.
