Red Eyes: Causes, Treatments, and When to See a Doctor
When your eyes turn red, it’s not just about looks—it’s your body sending a signal. Red eyes, a common symptom caused by swollen or inflamed blood vessels on the surface of the eye. Also known as bloodshot eyes, it can come from something simple like lack of sleep or something that needs quick attention, like an infection or injury. Most people assume it’s just allergies or tiredness, but red eyes can also be tied to conjunctivitis, an inflammation of the clear membrane covering the white part of the eye, or dry eye, a condition where your eyes don’t make enough tears or the tears evaporate too fast. These aren’t just annoyances—they can affect your vision, comfort, and even your ability to work or drive safely.
What’s causing your red eyes matters more than you think. If it’s eye infection, a bacterial or viral condition that can spread easily, you might need prescription drops. If it’s eye allergy, a reaction to pollen, dust, or cosmetics, antihistamines or avoiding triggers can help. Some medications, like blood pressure pills or antihistamines, can dry out your eyes and make them red. Even screen time and contact lenses play a role. You might not realize it, but using the wrong eye drops—like ones with decongestants—can make things worse over time. And if you’ve had a recent injury, sudden pain, vision changes, or light sensitivity, that’s not normal. That’s when you need to act, not wait.

You’ll see how red eyes connect to things like ocular migraines, allergic reactions to cosmetics, and even how certain medications can trigger or worsen the problem.
