Bloodshot eyes occur when the capillaries between the sclera, the white part of the eye, and the transparent layer on the surface of the eye dilate excessively and collect blood. This condition is often caused by environmental factors, lifestyle and certain health conditions. This condition can occur as a result of dilated or inflamed blood vessels in the eyes, but it can also occur for many other reasons.
Bloodshot eyes can usually be treated depending on the underlying cause and in some cases may go away on its own. However, it is important to consult an ophthalmologist in case of persistent or severe eye bleeding.
