Pink Eye and Stye Evaluation

Redness Alone Does Not Tell You Why an Eye Is Irritated

A red eye can come from a virus, bacteria, allergy, dryness or another problem. Pink eye (conjunctivitis) may cause watering, discharge, itching, burning or eyelids stuck together in the morning. A stye is different: it is a tender bump at the edge of the eyelid that can resemble a small pimple.

The cause matters because not every red eye needs antibiotics, and some eye problems require specialist evaluation. During a medical visit, the clinician can ask about the onset, eye discharge, exposures, contact lens use, vision changes and whether one or both eyes are involved.

Clues That Help Distinguish Causes

Watery discharge may accompany viral irritation. Thick discharge can occur with bacterial infections, while prominent itching in both eyes can suggest allergies. These patterns are useful but do not establish a diagnosis without examination. An eyelid bump may be a stye or another lid condition. Tell the clinician if you have a recent cold, were around someone with red-eye symptoms or have had similar episodes before.

What You Can Do Safely

Wash your hands, avoid touching or rubbing the eyes, and do not share towels, eye makeup or contact lens supplies. Stop wearing contact lenses until an appropriate clinician advises they are safe again. A clean warm compress can be helpful for some eyelid bumps; use gentle contact without squeezing or puncturing them. Use eye drops only as directed, particularly if redness began after a chemical exposure or injury.

Red Flags: Do Not Wait for a Routine Clinic Visit

Eye pain, light sensitivity, reduced or blurred vision, intense redness, an injury or symptoms in a contact lens wearer can require prompt ophthalmic assessment. Severe eye pain or vision loss warrants emergency care. The clinic can advise whether referral is the appropriate next step; a primary-care office cannot substitute for every type of eye examination.

Questions Patients Have

Is all pink eye contagious? No. Viral and some bacterial forms can spread, but allergic conjunctivitis is not contagious.

Do antibiotic drops help every red eye? No. Treatment depends on the cause and risks, and viral or allergic irritation does not automatically benefit from antibiotics.
