Red eyes are a common problem that is experienced by many people. It can happen because of various reasons, such as eye infections, allergies, or other underlying health issues.

In this article, we will discuss the causes, symptoms, and diagnosis of red eyes.

What are the Causes of Red Eyes?

There are several different causes of red eyes, which include:.

: Eye Infections

An eye infection can cause the eyes to become red. This is because the infection can cause inflammation, which makes the blood vessels in the eyes dilate, giving them a red appearance.

Some common eye infections that can cause red eyes include conjunctivitis and keratitis.

: Allergies

Allergies are another common cause of red eyes. When you come into contact with an allergen, such as pet dander, pollen, or dust mites, your eyes may become red, itchy, and watery.

This is because your body releases histamines to fight off the allergen, which can cause inflammation in the eyes.

: Dry Eyes

Dry eyes can also cause red eyes. Dry eyes occur when the eyes do not produce enough tears or when the tears evaporate too quickly. This can cause the eyes to become red, and they may feel irritated or gritty.

: Eye Strain

Eye strain can also cause red eyes. This can occur if you spend too much time looking at a computer screen or reading a book. Eye strain can cause the eyes to become dry and irritated, which can lead to redness.

: Other Underlying Health Issues

In some cases, red eyes can be a symptom of an underlying health issue. For example, high blood pressure, diabetes, or thyroid problems can cause the eyes to become red.

In these cases, it is important to seek medical attention to identify and treat the underlying health condition.

What are the Symptoms of Red Eyes?

The symptoms of red eyes can vary depending on the underlying cause. Some common symptoms may include:.

: Redness

The most noticeable symptom of red eyes is redness. The whites of the eyes may appear pink or red, and the blood vessels in the eyes may be more visible.

: Itching or Irritation

Red eyes may also feel itchy or irritated. This can be a symptom of allergies or dry eyes.

: Watery Eyes

If you have red eyes, you may also experience excessive tearing. This is a common symptom of eye infections and allergies.

: Sensitivity to Light

If your eyes are red, you may also experience sensitivity to light. This can be a symptom of certain eye infections.

How is Red Eyes Diagnosed?

If you are experiencing red eyes, you should visit an eye doctor for a proper diagnosis. During your appointment, your eye doctor may ask you about your symptoms and any underlying health conditions you may have.

They may also perform a physical exam, including an eye exam, to determine the underlying cause of your red eyes.
