Understanding the Cause of Red Eyes

Occasional eye redness is common and may result from fatigue, environmental irritation, or dryness. However, persistent or severe redness may indicate inflammation, infection, or another eye condition and should be evaluated by an eye care professional.

At Richlin Eye, our doctors diagnose and offer red eye treatment in Los Angeles and Beverly Hills. Through comprehensive eye examinations and advanced diagnostic tools, we identify the underlying issue and recommend treatment to restore comfort and protect eye health.

Understanding Red Eyes

Red eyes occur when the small blood vessels on the surface of the eye become enlarged or irritated. It may cause the white portion of the eye to appear pink, red, or inflamed.

The redness may affect one or both eyes and may occur suddenly or develop gradually. While some cases are temporary and resolve on their own, others may signal conditions such as infection, inflammation, allergies, or dryness that require treatment.

What Causes Red Eyes?

Red eyes can develop for many reasons. Minor irritation may occur from environmental factors such as wind, smoke, dust, or prolonged screen use. Allergies are also a common cause and may trigger redness along with itching and tearing. More serious causes may include eye infections, inflammation of the eye’s surface, corneal injuries, or conditions affecting the eyelids or tear film.

Contact lens irritation, dry eye syndrome, and blocked oil glands may also contribute to redness. Because many different conditions can cause red eyes, an accurate diagnosis is important for effective treatment.

How Red Eyes Are Diagnosed

Diagnosing the cause of red eyes begins with a comprehensive eye examination. During the visit, the doctor evaluates the surface of the eye, eyelids, and tear film to determine what is causing the inflammation. The diagnostic process may include:

    Symptom and Medical History Review

    The doctor discusses the onset of redness, associated symptoms, and potential environmental triggers.

    External Eye Examination

    The eyelids, conjunctiva, and cornea are examined for signs of irritation, infection, or injury.

    Ocular Surface Evaluation

    The surface of the eye is assessed for dryness, inflammation, or allergic reactions.

    Additional Testing if Needed

    Specialized tests may be used to rule out infection or other eye conditions. These evaluations help determine the cause of redness and guide appropriate treatment.

    Treatment Options for Red Eyes

    Treatment for red eyes depends on the underlying cause. Mild irritation may improve with lubricating eye drops and avoiding environmental triggers. If redness is caused by allergies, medicated eye drops may help reduce inflammation and itching.

    In cases of infection or inflammation, prescription medications may be recommended to treat the condition and relieve symptoms. Our doctors tailor every red eye treatment in Beverly Hills to the specific causes of redness to ensure the most effective care.

    When to See an Eye Doctor

    Occasional redness may resolve on its own, but an eye care professional should evaluate persistent or severe symptoms. You should schedule an eye exam if you experience:

    • Persistent redness lasting more than a few days
    • Eye pain or pressure
    • Sensitivity to light
    • Blurred or decreased vision
    • Discharge from the eye
    • Redness following an eye injury

    Prompt evaluation helps identify the cause and prevent complications.
