bloodshot

If someone's eyes are bloodshot, it means they look red and irritated—as if the tiny blood vessels on the white of the eye have become swollen or dilated. Think of a long night, allergies flaring up, or staring at a screen for too long. A detective in a noir film might describe a suspect's eyes as "bloodshot with exhaustion and desperation." It's not usually a serious condition on its own, but it can be a sign of something else going on. You wouldn't say your favorite blue eyes are bloodshot; the term implies irritation or strain rather than natural pigment.

The word "bloodshot" describes eyes that appear red and inflamed, as if shot through with streaks of blood. This redness isn't actually blood pooling inside the eye (usually!), but rather a sign of dilated blood vessels on the surface. These tiny vessels become enlarged due to various reasons: irritation from dryness, allergies, lack of sleep, straining your eyes, or even something more serious like an infection.

You'll often encounter "bloodshot" when describing someone who looks tired, stressed, or unwell. A character in a story might have "bloodshot eyes that betrayed his sleepless nights," hinting at worry or exhaustion. It's also commonly used to describe the aftermath of crying—those tear-filled moments can leave your eyes looking distinctly bloodshot.

While often temporary and harmless, persistently bloodshot eyes warrant a visit to a doctor, as they could indicate an underlying medical condition like conjunctivitis (pinkeye) or glaucoma. So, if you notice that telltale redness, pay attention to any accompanying symptoms—and don't hesitate to seek professional advice. Ultimately, "bloodshot" is a visual cue signaling irritation, fatigue, or potentially something more serious happening within the delicate landscape of your eyes.
