A red or irritated eye may be conjunctivitis, allergy or another eye problem. Viral, bacterial and allergic causes have overlapping symptoms and need different management. A visit checks for features that require an eye specialist or emergency care rather than assuming every red eye needs an antibiotic.
The clinician considers discharge, itching, pain, vision changes, exposure and contact-lens use. Antibiotics do not treat viral or allergic conjunctivitis. An eye examination may be needed to distinguish a surface irritation from a corneal or deeper problem. A photograph alone may not settle the diagnosis.
Seek assessment for persistent redness, discharge or uncertainty. Tell the team about contact lenses, injury, chemical exposure, eye surgery and immune suppression. A newborn with a red or draining eye needs prompt medical assessment. Contact-lens wear changes the concern for corneal infection.
Describe when symptoms began, whether one or both eyes are affected and any change in vision. The clinician discusses the likely cause and whether drops, hygiene measures or specialist review are needed. Ask about school or work return according to the diagnosis and the requesting setting's rules.
Remove contact lenses and avoid wearing them until a clinician says it is safe. Bring medicine and allergy information. Do not use another person's drops or leftover steroid eye drops. Wash hands and avoid sharing towels or eye makeup.
Eye pain, sensitivity to light, reduced vision, significant injury or a chemical exposure needs urgent eye assessment. Sudden vision loss is an emergency. A painful red eye in a contact-lens wearer should not be treated as routine pink eye through a remote visit alone.
Contact the clinician if symptoms worsen or do not improve within the advised interval. Continuing symptoms after an antibiotic may reflect another cause and need reevaluation. Ask whether lenses, cases or makeup should be replaced under the care plan.
Confirm whether the clinic can perform the necessary eye examination or arrange urgent specialist care. A virtual visit may triage symptoms but cannot provide every eye test. No universal antibiotic, same-day specialist slot or fixed return-to-school rule is established.

Persistent symptoms after antibiotic drops need reassessment because viral, allergic and other eye conditions can resemble bacterial conjunctivitis. Do not keep adding drops or use a leftover steroid. Eye pain, light sensitivity, vision change or a painful red eye with contact lenses needs urgent eye assessment.

Viruses, bacteria and allergens commonly cause conjunctivitis. Viral and bacterial forms can spread between people, including through contaminated hands or shared items. Allergic conjunctivitis is not contagious. Symptoms overlap, so appearance alone does not establish the cause or a precise end to contagiousness. Wash hands and avoid sharing towels, eye makeup or drops. Follow clinician and school or workplace advice for return, especially when activities involve close contact. Do not assume 24 hours of any eye drop clears every case. Eye pain, light sensitivity, vision change or a painful red eye with contact lenses needs urgent eye assessment.
Duration depends on the cause. CDC says viral conjunctivitis often clears in 7–14 days, but it can take 2–3 weeks or longer. Mild bacterial disease may improve within 2–5 days without antibiotics yet take up to 2 weeks to clear completely. Allergic symptoms depend on the exposure and treatment. Those ranges do not replace an examination or guarantee when someone stops being contagious. Worsening symptoms, eye pain, light sensitivity or reduced vision needs assessment. If diagnosed bacterial pink eye does not improve after 24 hours of antibiotic use, contact the treating clinician. Newborn eye symptoms need immediate medical review.
Choose care according to the problem and how urgently you need help. Urgent care assesses non-emergency illnesses and minor injuries.
