Vol.6 Why do eyes bleed?

Have you ever looked in the mirror and been surprised to see the whites of your eyes red and bloodshot? Why do our eyes become red and bloodshot when they are white? In this study, we introduced bloodshot eyes.
Conjunctival congestion
The thin membrane that covers the surface of the white eye is called the conjunctiva. Normally, the conjunctiva appears white but contains small blood vessels near its surface. Conjunctival redness is caused by the small blood vessels.

The cause is said to be “eye fatigue.” Prolonged exposure to TV or computer screens can cause tired eyes, which, in turn, causes blood vessels to swell, resulting in hyperemia. In such cases, it seems a good idea to rest with a tired eye. In addition, people with dry eyes or those who use contact lenses for long periods experience blood vessel dilation and hyperemia as the cornea attempts to absorb more oxygen.

However, if you experience symptoms such as itching or excessive eye discharge in addition to bloodshot eyes, you may experience inflammation, such as conjunctivitis, and should consult an ophthalmologist.

 

Subconjunctival hemorrhage
Unlike conjunctival hemorrhages, the white part of the eye may appear bright red. This condition is referred to as a subconjunctival hemorrhage. It is caused by the rupture of a blood vessel in the conjunctiva, resulting in bleeding that turns the eye bright red.

Irritation can be caused by hard blows or rubbing the eyes. However, there seems to be no concern, as it usually does not affect vision and heals on its own within a week or two. However, if symptoms such as eye discharge or pain occur, it is a good idea to have an eye doctor examine the eye.

Bloodshot eyes can make one look tired. We should be aware of resting our eyes after frequent use and keeping them clean and bloodshot-free.
