Myth or Fact: Do All Red Eyes Need Eye Drops?
Red eyes are a common concern among people of all ages. They can result from something as mild as lack of sleep or as serious as an eye infection or glaucoma. A popular myth is that “all red eyes need eye drops.” This belief has led many to self-medicate—often with harmful consequences.
But is this claim true? Let’s unpack the truth behind red eyes and explore the dangers of applying “anyhow” eye drops without a proper prescription.

Understanding Red Eye: Not All Redness is the Same
Red eye is a symptom—not a diagnosis. It can be caused by several factors, ranging from harmless irritations to severe eye conditions. Common causes include:
• Allergies
• Eye fatigue or strain
• Dry eyes
• Dust or smoke exposure
• Infections like conjunctivitis (Apollo)
• Uveitis or keratitis
• Acute glaucoma
• Trauma or injury to the eye
While some red eyes may clear up with rest or artificial tears, others require urgent medical attention. Therefore, assuming that every red eye needs just any over-the-counter drop is not only incorrect—it can be dangerous.

The Dangers of Using “Anyhow” Eye Drops Without Medical Advice
In Nigeria and many other parts of the world, self-medication is common. People often walk into pharmacies and request “any eye drop for red eye,” sometimes even using leftover medications or those recommended by friends. Unfortunately, this habit can do more harm than good.
Here’s why:
1. Steroid Misuse Can Lead to Blindness
Many eye drops contain corticosteroids which reduce inflammation. However, using steroid eye drops without medical supervision can worsen infections like herpes simplex keratitis or trigger glaucoma—leading to irreversible vision loss.
2. Masking of Underlying Eye Diseases
Some drops may reduce redness temporarily, but they can mask symptoms of serious conditions like glaucoma, iritis, or corneal ulcers, delaying proper treatment and causing long-term damage.
3. Antibiotic Resistance
Using antibiotic eye drops unnecessarily contributes to antimicrobial resistance, making future infections harder to treat.
4. Allergic Reactions and Toxicity
Some eye drops contain preservatives or chemicals that can irritate the eyes or trigger allergic reactions, especially when misused or overused.
5. Worsening of Red Eye
Instead of curing the problem, some eye drops (especially decongestants) can cause a “rebound effect,” making the redness worse once the effect wears off.

So, What Should You Do When You Have a Red Eye?
The best approach is to:
• Avoid self-medication.
• Visit an eye hospital or qualified ophthalmologist for a comprehensive eye examination.
• Avoid sharing eye drops with others, even if their symptoms appear similar.
• Practice good hygiene—especially when handling your eyes or applying any eye medication.

Why Professional Diagnosis Matters
At St. Mary’s Catholic Eye Hospital, we’ve seen numerous cases where patients unknowingly worsened their conditions by using the wrong eye medications. A red eye could be a sign of something as minor as dryness or as severe as acute angle-closure glaucoma, which is a medical emergency.
Only a trained eye care professional can:
• Determine the exact cause of the redness
• Prescribe the appropriate medication
• Monitor your progress and avoid complications

Conclusion: Treat Your Eyes with Care
Your eyes are precious, and using the wrong medication—even if it seems harmless—can cause lifelong damage. Redness in the eye is a symptom, not a one-size-fits-all diagnosis. Don’t gamble with your vision. Seek professional care.
Remember: Not all red eyes need eye drops. But all red eyes deserve attention from an eye care professional.
