Why are there bloodshot eyes_What is the reason for bloodshot eyes

Many people have experienced red bloodshot eyes in their lives. When this happens, they feel scared. The main reason for the appearance of red bloodshot eyes is excessive eye fatigue. Of course, the appearance of red bloodshot eyes is also related to the environment, temperature and other external stimuli. No matter what the cause of the red bloodshot phenomenon is, the symptoms must be relieved in time.

1. Excessive liver fire

According to traditional Chinese medicine, the liver opens up to the eyes, and red, bloodshot eyes are often a sign of liver fire. Especially people with excessive liver fire are prone to symptoms of red bloodshot eyes. In addition, drunk people often have red faces and eyes, and their eyes are full of red bloodshot. This is because alcohol is very hot and damages the liver, causing a large amount of blood to rush to the head and body. As a result, the liver blood will be overdrawn, the liver fire will be hyperactive, and red bloodshot eyes will appear.

Countermeasures: Excessive liver fire is mainly caused by irregular life and depressed mood, so you should pay attention to a regular life, regulate your emotions and keep a good mood.

2. Lack of sleep

If you stay up late for a long time and lack of sleep, the blood vessels in your eyes will become congested and the red bloodshot will be very obvious. In addition, since people who stay up late need to overdraw liver fire to maintain energy, which leads to excessive liver fire, and the liver opens up to the eyes, there are many bloodshot eyes after staying up late.

Countermeasures: Be sure to avoid staying up late and ensure 8 hours of sleep every day. Adequate sleep helps moisturize the eyes and reduce bloodshot eyes.

3. Wearing contact lenses for a long time

Contact lenses are in direct contact with the cornea. If worn for a long time, the eyes will be isolated from the air, causing corneal hypoxia and chronic conjunctival inflammation, which will lead to dilation of conjunctival blood vessels and cause red bloodshot eyes. Moreover, contact lenses easily absorb bacteria. If you do not pay attention to regular care and cleaning, or wear contact lenses with dirty hands, it will cause eye infection and inflammation, and red bloodshot.

Countermeasures: It is best not to wear contact lenses and choose frame glasses. If you need to wear contact lenses, it should not exceed 8 hours a day. Pay attention to cleanliness and hygiene, and use professional tools to wear contact lenses.

4. Excessive eye fatigue

Many times we often work overtime or face the screen for a long time, or read in an environment with too strong or too dark light. These can cause great harm to the eyes, make the eyes overly tired, cause blood vessels to dilate, and cause red bloodshot eyes.
