5 Causes of Red Eye
Red eyestypically occurs due to minor irritation of the white part of the eye that causes blood vessels to become inflamed. There are many possible causes of red eye, and it is important to identify the underlying cause to ensure proper treatment. Five of the most notable causes of red eye are infection, trauma, irritation, drugs, and inflammation.
Common causes of red eye
The five common causes of red eye listed below are still relatively broad. The following review highlights specific reasons why you may experience infection, trauma, irritation, or inflammation that leads to red eye, along with identifying certain medications that may increase the risk of red eyes developing.
There are certain eye-related infections that can cause red eye. These are typically a more serious concern that requires more extensive treatment, although treating an eye infection is a non-invasive process. The most notable types of eye infections that can cause red eye include:
- Conjunctiviits (pink eye)
- Corneal ulcers
Red eye may also be a symptom of the common cold, measles, and other common illnesses. It is important to seek professional assistance if the red eye may be caused by an infection or if the red eye exists along with other concerning symptoms such as eye discomfort, itching, and dryness.
Among other concerning symptoms, trauma can cause red eye. This can be in the form of more obvious trauma such as a blow to the eye during sports, or it can be more subtle such as scratches causes by wearing your contact lenses. If there are any incidents that may cause trauma to the eyes that subsequently lead to red eye, the issue should resolve itself once the issue causing the trauma is addressed. If it does not resolve itself, an optometrist may recommend a form of red eye treatment.
Certain irritants can also lead to vessels on the eye becoming inflamed. The most common type of irritant is dry air. This can cause dry eye which subsequently causes the vessels to become irritated and inflamed, leading to red eye. Other irritants include dust, excessive sun exposure, and allergens.
Red eye is a common side effect of certain prescribed and recreational drugs. One common example of a drug that leads to red eye is marijuana, which may be used to treat health issues such as glaucoma or could be consumed for recreational purposes. In any case, reviewing the side effects of any drugs you take is important for determining the cause of red eye.
