The term “bloodshot eyes” is used to describe eyes that appear red. It is a very common issue and while it may appear alarming, it is rarely due to a serious condition. Bloodshot eyes usually occur when the blood vessels in the surface of the eye become swollen or dilated. It can be caused by an infection, injury, illness, or various other causes.

Generally harmless, it responds well to home remedies and over-the-counter treatments. However, the presence of pain, headaches, blurry vision, and light sensitivity should prompt the patient to seek medical attention. In some cases, a proper diagnosis and prescription medication may be required. This article only highlights some of the common causes for bloodshot eyes. It is always best to check with a medical professional if symptoms persists.

1. Eye Strain

Eye strain, or asthenopia, occurs when you are concentrating on a task that requires constant focus from the eyes. Continuously focusing on a computer screen, phone, or book causes tightening of the ciliary muscles. This results in discomfort and irritation. Patients with eye strain may have bloodshot eyes, pain around or in the eyes, headaches, blurry vision, fatigue, and double vision.

Due to advancing technology, eye strain is becoming increasingly common. Treatment is generally not required. However, it can be prevented by allowing the eyes to focus on distant objects at least once an hour. As the activity continues, the eye strain may worsen as there is a buildup of fatigue in the eye muscles.
