Red Eye Causes

What is Red Eye?

CSI Dry Eye Software

Red eyes and dry eyes are similar in that they can both cause extreme discomfort to the eyes. While there is some overlap in the symptoms, technically speaking, both are symptoms of deeper issues. Red eyes are often associated with pain, irritation, burning, itching, dryness, discharge, watery eyes, blurry vision, and sometimes, sensitivity to light. A red or bloodshot appearance is the manifestation of these symptoms and is the result when the blood vessels in your eyes become swollen due to irritation, environmental factors, or an infection. Depending on the causes of red eyes, the symptoms can be mild or severe. They can also be a manifestation of dry eye disease.

Causes of Red Eye

Associated Conditions

The causes of red-eye can be environmental or the result of an internal condition or infection. When caused by airborne allergens, smoke, dryness, or another environmental factor, red eye is typically not severe and can be treated with over-the-counter eye drops. If symptoms persist, the cause may be related to something slightly more severe such as allergies, dry eye disease, or pink eye. While these conditions may require consultation with a doctor, they are still treatable. Red eyes become a concern when caused by an eye infection, trauma, or a disease, such as glaucoma or uveitis. Certain lifestyle factors may also result in the symptoms of red eyes. For example, excessive alcohol consumption, marijuana, and insufficient sleep may require lifestyle changes to reverse the symptoms.

Determining the causes of red eyes

Your doctor will be best able to determine the reasons for your red eyes. Though red-eye is typically easy to treat either through over-the-counter or prescription medication or simple lifestyle changes, allowing the symptoms to worsen without seeking proper care can lead to further complications.
