For most eye infections, your first stop should be your primary care doctor or an optometrist. Either can diagnose common infections like pink eye, prescribe antibiotic drops if needed, and refer you to a specialist if something more serious is going on. You don’t usually need an emergency room unless you’re experiencing severe pain, sudden vision loss, or extreme sensitivity to light.
The right provider depends on how bad your symptoms are, how quickly they came on, and whether you wear contact lenses. Here’s how to figure out where you need to be.
Start With Your Primary Care Doctor or Optometrist
A primary care doctor can handle the most common eye infection: conjunctivitis, or pink eye. Bacterial pink eye often clears up on its own in 2 to 5 days, though it can linger for up to two weeks. Antibiotics can shorten that timeline and reduce the chance of spreading it to others. Viral pink eye, which is more common, typically resolves in 7 to 14 days without treatment, though stubborn cases can take two to three weeks.
An optometrist is another solid option and may actually be better equipped than a general doctor for eye-specific problems. Optometrists have specialized training in eye conditions and can prescribe medications for infections in most states. They also have the instruments to look closely at your cornea and the front of your eye, which matters if the infection is anything beyond garden-variety pink eye. If your symptoms are straightforward (redness, discharge, crustiness overnight, a gritty feeling), either a primary care doctor or optometrist will get you sorted.
When You Need an Ophthalmologist
An ophthalmologist is a medical doctor who specializes in eyes. They can perform surgery, treat complex diseases, and handle infections that are beyond what a general doctor or optometrist would manage. You probably won’t book directly with an ophthalmologist as your first step. Instead, your primary care doctor or optometrist will refer you if they spot something concerning.
The American Academy of Ophthalmology recommends a prompt referral for any significant eye pain, vision loss, inflammation of the eye itself, or opacities (cloudy spots) in the normally clear parts of your eye. If you wear contact lenses and develop pain, light sensitivity, and tearing, you could have keratitis, an infection of the cornea. This is one situation where getting to an eye specialist quickly matters a lot. With aggressive bacteria, corneal damage can become severe within 24 to 48 hours.
When to Go to the Emergency Room
Most eye infections don’t require an ER visit. But certain symptoms signal that something more dangerous than pink eye is happening, and those need immediate attention:
- Sudden decrease in vision that doesn’t clear with blinking
- Moderate to severe eye pain, especially pain that worsens with eye movement
- Sensitivity to light so intense that even normal indoor lighting is uncomfortable
- Eye pain combined with nausea, vomiting, or headache
- Swollen, red eyelids with fever, which could indicate orbital cellulitis
These symptoms overlap with conditions like corneal ulcers, uveitis (inflammation inside the eye), and acute glaucoma, all of which can threaten your vision permanently. The ER can stabilize you and connect you with an ophthalmologist on call. If your vision in the affected eye is severely reduced, you may need emergency intervention the same day.
Urgent Care: A Reasonable Middle Ground
If your regular doctor can’t see you today and your symptoms feel like more than mild irritation, an urgent care clinic is a practical option. Most urgent care providers can diagnose pink eye and prescribe drops. They’re a good fit for symptoms that aren’t emergencies but also shouldn’t wait several days for a scheduled appointment: moderate redness, worsening discharge, or an infection that hasn’t improved after a few days of home care.
What urgent care can’t do well is examine the deeper structures of your eye. If they suspect something beyond a surface-level infection, they’ll send you to a specialist or the ER.
What About Children?
For kids, start with their pediatrician. Pink eye is extremely common in children, and a pediatrician can diagnose and treat it in a standard office visit. Nationwide Children’s Hospital recommends seeing the doctor right away if you suspect conjunctivitis, partly because bacterial cases are contagious and schools often require treatment before a child can return.
Call back or seek further care if your child shows no improvement after three days on prescribed medication, develops eye pain or light sensitivity, has blurred vision that doesn’t clear with blinking, or if another family member starts showing symptoms. Painful eye movement in a child always warrants a same-day call to the pediatrician.
How to Tell What You’re Dealing With
The type of infection you have influences how urgently you need to be seen. Here’s a quick comparison of the most common ones:
Conjunctivitis (pink eye) causes redness, discharge that may be watery or pus-like, itchiness, and a gritty sensation. You might wake up with your eyelids crusted shut. It’s uncomfortable but rarely dangerous, and it’s the infection most people are dealing with when they search for help.
Keratitis affects the cornea and is more serious. Symptoms include pain, light sensitivity, tearing, blurry vision, and a feeling like something is stuck in your eye. Contact lens wearers are at higher risk. This needs prompt treatment, ideally from an optometrist or ophthalmologist rather than a general doctor.
Orbital cellulitis is an infection of the tissue around the eye. It causes swelling of the eyelids and surrounding skin, pain with eye movement, and sometimes fever. This is a medical emergency, especially in children, and requires an ER visit.
Insurance and What to Expect
An eye infection is a medical problem, not a vision problem. That means it’s covered under your medical insurance, not your vision plan. This is true even if you see an optometrist. The visit will be billed as a medical exam, so your regular copay and deductible apply. You don’t need a separate vision insurance policy to get an eye infection treated.
Before your appointment, it helps to note a few things so you can give your provider a clear picture: when your symptoms started, whether you wear contact lenses (and when you last wore them), what your discharge looks like (watery, thick, yellow, or green), whether light bothers you, whether your vision seems different, and whether anyone around you has similar symptoms. If you’ve already tried over-the-counter drops, mention those too. These details help your provider distinguish between a viral infection that just needs time and a bacterial one that needs medication.
