Red eyes are a common condition that causes the whites of the eyes to appear bloodshot and red. Several things, including dry eye, allergies, and irritation, can cause red eyes.
Red eyes may signify a more serious medical condition, such as conjunctivitis or glaucoma.
If you are experiencing red eyes and are concerned about your health, you must seek medical advice for proper treatment.
What Causes Red Eyes?
There are many possible causes of red eyes. Some common causes include:
- Allergies: Red eyes can be caused by allergies to pollen, dust, or animal dander.
- Infection: Bacterial or viral infections can cause redness and swell in the eyes.
- A dry eye occurs when the eyes don’t produce enough tears or evaporate too quickly.
- Eye strain: Prolonged use of computers or other electronic devices can cause eye strain, which can lead to red eyes.
- Environmental factors: Wind, dry air, and exposure to irritants like smoke or pollution can all cause redness in the eyes.
- Physical irritation: Foreign objects in the eye, such as a piece of dust or sand, can cause redness and irritation.
- Conjunctivitis (pink eye): Red eyes can be caused by infection or inflammation of the conjunctiva. If you have red eyes, you may feel burning and itching sensations and increased sensitivity to light.
- Uveitis: Red eyes can be a symptom of uveitis, an inflammation of the eye’s middle layer known as the uvea. Uveitis can often cause pain, blurred vision, floaters, and other visual disturbances. Prompt diagnosis and treatment are essential to help prevent long-term damage to the eye and vision loss.
- Scleritis: Red eyes are commonly a symptom of scleritis, which is an inflammation of the sclera. The sclera is the white part of our eye, which lies beneath the cornea and protects the delicate inner structures that form our vision. Scleritis tends to cause red swelling, eye pain, and irritation.
- Episcleritis: Red eyes can be a sign of episcleritis, an inflammation of the episclera, a thin tissue layer covering the sclera. Symptoms can include pain, itchiness, and redness in one or both eyes.
- Subconjunctival hemorrhage: This is a small blood vessel that breaks and bleeds under the conjunctiva, causing redness in the eye.
- Corneal abrasions: A scratch or injury to the cornea can cause redness and discomfort.
If you’re experiencing red eyes and are unsure what’s causing it, it’s a good idea to see a doctor or eye specialist for an evaluation. They can help determine the cause of your red eyes and recommend the appropriate treatment.
