Why do fluorescent lights make your eyes red?

Fluorescent lights can cause eye redness primarily due to their flickering nature and the type of light they emit. The flicker, which is often imperceptible, can lead to eye strain and fatigue, making the eyes feel uncomfortable and appear red. Additionally, fluorescent lights emit a harsh, cool light that can cause glare and discomfort, further contributing to irritation. Prolonged exposure can exacerbate these effects, especially in individuals sensitive to artificial lighting.
