Red eyes are a common problem and can happen for many different reasons. Sometimes the cause is minor, like irritation from lack of sleep or allergies. In other cases, redness may be a sign of an underlying eye condition that requires professional care.
Because red eyes can be linked to everything from dry eye to infections or inflammation, a comprehensive eye exam is often the best way to determine what’s causing your symptoms and how to treat them effectively.
At Plainfield Vision Care and Naperville Vision Care, we help patients identify the source of red, irritated eyes and recommend treatment options based on their individual needs. In this blog, we’ll cover some of the most common causes of red eyes, symptoms to watch for, and when it’s time to schedule an eye exam.
Why are my eyes red?
The white part of the eye contains tiny blood vessels that can expand or become irritated. When this happens, the eyes may appear pink or red.
Sometimes redness develops suddenly, while other times it gradually worsens throughout the day, depending on the underlying cause.
Common causes of red eyes
Red eyes can develop for a variety of reasons, ranging from temporary irritation to chronic eye conditions. Identifying the underlying cause is important because the right treatment depends on what is contributing to redness in the first place.
Dry eye disease
Dry eye is one of the most common causes of red, irritated eyes.
Your tears help keep your eyes lubricated, smooth, and comfortable. When tear production is reduced or tears evaporate too quickly, inflammation can develop on the surface of the eye.
Dry eye symptoms may include:
- Redness
- Burning or stinging
- Grittiness
- Blurry or fluctuating vision
- Watery eyes
- Eye fatigue
Many people notice dry eye symptoms worsen during screen use, reading, or driving.
Allergies
Environmental and seasonal allergies can make the eyes appear red, watery, and itchy. Pollen, pet dander, dust, and mold are common triggers.
Unlike some other causes of redness, allergies are often accompanied by significant itching.
Contact lens irritation
Contact lenses can sometimes cause redness if they become dry, accumulate deposits, or are worn longer than recommended.
Poor lens fit or overwearing lenses may also reduce oxygen reaching the cornea, leading to irritation and discomfort.
Eye infections
Both viral and bacterial eye infections can cause redness, irritation, discharge, and sensitivity.
Pink eye (conjunctivitis) is one of the most well-known causes of red eyes and may spread easily depending on the type of infection.
Digital eye strain
Long hours spent on computers, phones, and tablets can strain the eyes and contribute to redness. People tend to blink less during screen use, which can increase dryness and irritation over time.
Environmental irritants
Smoke, wind, chlorine, air pollution, and dry indoor air can irritate the eyes and cause redness.
When should you see an eye doctor for eye redness?
Occasional redness may resolve on its own, but some symptoms should not be ignored.
It’s important to schedule an eye exam if you experience:
- Persistent or recurring redness
- Eye pain or light sensitivity
- Blurry vision
- Swelling or discharge
- Redness in only one eye
- Symptoms that worsen instead of improving
How a comprehensive eye exam can help
A comprehensive eye exam can help uncover why your eyes are red, irritated, or uncomfortable. During the exam, your eye doctor will carefully evaluate the surface of your eyes, your tear quality, contact lens fit, and your overall eye health.
Rather than masking symptoms with over-the-counter drops, identifying the underlying cause allows treatment to be tailored to your specific needs.
Depending on what’s contributing to your symptoms, treatment recommendations may include:
- Lubricating eye drops
- Prescription medications
- Allergy management
- Dry eye treatment
- Contact lens adjustments
- Lifestyle or environmental changes
