My eyes are red and bloodshot.

We all know that human eyes are very important to people, so many people often do some eye exercises to protect their eyes. But sometimes they have to stay up late because of work and do not have proper rest. When they wake up the next morning, there will be a lot of red bloodshot eyes, which look like they are about to burst. It is very harmful to the eyes. So what should you do if your eyes have red bloodshot eyes that look like they are about to burst?

Normally, we have a clear distinction between black and white. The outermost part of our black eyeball is the cornea (of course, ignoring the tear film on the cornea), but the cornea is colorless and transparent. Why is it black? This is because there is a structure behind our cornea called the iris, which is rich in pigments, and the pigments contained in different races may be different. We Chinese are generally dark brown, which looks like black eyeballs.

What is the white of the eyeball? It is called the sclera. It is the tough wall of the entire eyeball that supports the eyeball. It is opaque and porcelain white, commonly known as the white of the eye, and has very few blood vessels.

This is because the surface of the sclera is covered with a thin layer of tissue - the conjunctiva. It is soft, smooth and transparent, and contains abundant capillaries. Under normal circumstances, they are not visible to the naked eye. We can understand that these blood vessels are in a dormant state, but once stimulated, such as infection, injury, excessive fatigue, etc., the "dormant" blood vessels will expand and become congested, and this is the bloodshot we see.

Of course, some people are born with thicker eye blood vessels than others, and when our eyes are over-tired or infected, the blood vessels can rupture and cause retinal hemorrhage.

Therefore, friends who have bloodshot eyes need to pay attention, because bloodshot eyes definitely mean that the eyes are in a sub-healthy state. A normal person's eyes have clear black and white.

Possible causes of red bloodshot eyes

1. Overuse of eyes

For office workers, this may be the norm: looking at the computer and reading documents at work, watching TV and playing with the phone after get off work, and lowering the head to continue browsing on the phone when bored on the way. However, if you do not pay attention to resting your eyes, it will cause excessive strain on your eyes, which will cause red bloodshot eyes.

2 Local infection

Rubbing your eyes with your hands or foreign objects entering your eyes may cause bacteria or viruses to invade your eyes, causing local infection of the eyes and the appearance of red bloodshot.

3. Abuse of cosmetics

Nowadays, many women who love beauty like to put on eye makeup. However, long-term heavy makeup may irritate the eyes, damage the skin around the eyes, destroy the skin's stratum corneum, and weaken the elasticity of capillaries, causing them to rupture or dilate, thereby causing red blood streaks. Therefore, you should pay attention to protecting your eyes when using cosmetics or removing makeup.

4. Wearing contact lenses

If first-time wearers cannot wear and care for the lenses correctly, red bloodshot eyes are likely to appear; wearing the lenses for too long may cause corneal hypoxia and redness; if the contact lenses press too tightly on the eyeballs or the lenses have poor oxygen permeability, red bloodshot eyes may also appear; some people are allergic to certain chemicals in the solutions used to clean or soak and maintain contact lenses, which can also cause red eyes.
