Red Eyes: Causes and Treatments
What Are Red Eyes?
Red eyes, also known as bloodshot eyes, occur when the tiny blood vessels on the surface of the whites of your eyes expand. This can be caused by a variety of factors, including:
- Eye irritation (e.g., from allergies, smoke, or dust)
- Eye injury
- Infection (e.g., conjunctivitis)
- Dry eyes
- Lack of sleep
- Alcohol consumption
- Certain medications
When to Seek Medical Attention
In most cases, red eyes are not a serious condition and will resolve on their own within a few days. However, it is important to seek medical attention if you experience any of the following symptoms:
- Severe pain
- Loss of vision
- Eye discharge that is thick, yellow, or green
- Light sensitivity
- Swelling or redness around the eye
Treatment Options
The treatment for red eyes will depend on the underlying cause. In most cases, simple home remedies, such as applying a cold compress or using artificial tears, can help to relieve symptoms. However, if the redness is caused by an underlying medical condition, your doctor may prescribe medication or other treatment options.
