Redness is a sign — not a diagnosis
Red or bloodshot eyes occur when the blood vessels on the surface of the eye become dilated or inflamed. The causes range widely — from something as simple as dry eye disease or screen fatigue to more urgent conditions like elevated eye pressure or corneal infection. Because so many conditions can look the same from the outside, a proper evaluation is the only way to know what you're actually dealing with.
Red eyes don't always have an obvious cause
Many people with chronically red eyes chalk it up to tiredness or allergies — and sometimes they're right. But other times, the underlying cause requires targeted treatment.
Dry eye & tear film issues
One of the most common causes of red eyes. When the eye surface lacks adequate lubrication, blood vessels dilate in response to irritation. Dry eye disease often presents alongside burning, grittiness, or fluctuating vision.
Allergies & environmental irritants
Seasonal pollen, pet dander, smoke, and certain contact lens solutions can trigger allergic conjunctivitis — causing bilateral redness, itching, and watery eyes. Often worse during allergy season or in dry, dusty environments.
Infection & more serious conditions
Pink eye, bacterial or viral infections, uveitis, and even acute glaucoma can all present with red eyes — some requiring urgent treatment. Pain, vision changes, or light sensitivity alongside redness are red flags.
Finding the cause — not just treating the symptom
When you come in for red eyes, we take a systematic approach to identify the root cause rather than guessing or defaulting to a single treatment.
Symptom & History Review
We start by understanding when redness occurs, how long it lasts, what makes it better or worse, and whether other symptoms are present — pain, itching, discharge, or vision changes.
Slit-Lamp Examination
A detailed look at the conjunctiva, cornea, eyelids, and anterior chamber lets us identify the location and nature of inflammation — and rule out serious conditions.
Targeted Treatment Plan
Treatment depends on the cause. That might mean lubricating drops for dry eye, antihistamine drops for allergies, prescription medication for infection, or referral for more complex conditions.
Common questions about red eyes

Some mild redness on waking is common — especially in dry environments or for contact lens wearers. If it clears quickly, it's usually not a concern. Persistent morning redness, crusting, or discharge is worth having evaluated.
Yes. Extended screen time significantly reduces blink rate, which allows the tear film to evaporate and the ocular surface to dry out. This triggers inflammation and redness. Taking regular screen breaks and using lubricating drops can help, but if redness is persistent, an evaluation for dry eye disease is worthwhile.
Seek prompt care if your red eyes are accompanied by pain, light sensitivity, sudden vision changes, or a cloudy or hazy appearance. These can indicate a more serious condition that needs same-day evaluation.
Red eyes in children are often caused by conjunctivitis (pink eye), which spreads easily in school settings. Bilateral itchy, watery eyes often point to allergies. It's worth having children evaluated promptly, especially if one eye is involved or symptoms are worsening.
In acute angle-closure glaucoma, sudden redness can accompany severe eye pain, nausea, and blurry vision. This is a medical emergency. If you experience this combination of symptoms, call us immediately or go to urgent care.
Don't ignore what your eyes are trying to tell you
Red eyes can have a simple fix — or point to something that needs attention. A quick evaluation puts you on the right path.
