Red eyes often cause discomfort and interfere with activities. This fairly common complaint can be caused by many things. So, what are the causes of red eyes and how to prevent them?
Red eye is a generally harmless condition. However, this condition can interfere with vision, especially when doing activities or communicating with other people.
Although it seems mild, you still need to be vigilant, especially if the red eyes are also accompanied by pain, soreness, itching, watering, pus (swelling), or swelling.
Causes of Red Eyes
Red eyes are caused by swelling or widening of the blood vessels at the base of the white membrane (sclera) of the eye. This condition occurs due to the entry of dust or foreign particles into the eye, infection, allergies, injury, sun exposure, or dry eye conditions.
Not only that, red eyes can also be caused by other things, such as:
Conjunctivitis is one of the most common causes of pink eye. This condition causes the blood vessels in the eye to swell, making the eye look red, and feel as though it feels tight.
Conjunctivitis can be caused by an infection, either viral or bacterial, or an allergic reaction and irritation of the eye. Conjunctivitis due to infection can be transmitted to other people, while conjunctivitis caused by allergies or irritation is not contagious.
Allergic conjunctivitis can cause symptoms, such as itchy, watery, and swollen eyes. If it is caused by a bacterial infection, the symptoms may be accompanied by pus (pus) in the eye, pain or itching, and redness and swelling.
Viral infections of the eyes also make the eyes red, itchy, and watery. To prevent this, avoid factors that can cause red and itchy eyes, such as dust, and avoid the habit of rubbing or scratching the eye area.
2. Dry eyes
Dry eye can occur when the tear glands don't produce enough tears or because too many tears evaporate into the air. This can make the eyes feel dry and irritated, making them look red.
Dry eyes can also be triggered by hot and dry or windy weather, continuous use of contact lenses, or inflammation of the eyelids due to certain diseases such as lupus, rheumatoid arthritis, and Sjögren's disease.
Too long working in front of the computer can make your eyes feel tired, dry, or even watery all the time. In fact, this condition is sometimes accompanied by headaches and extreme fatigue.
It should also be noted that the eyes blink less frequently when you are in front of a computer screen or television. This is what makes the eyes dry and red.
Make sure to take short breaks every few hours or apply eye drops if needed, to keep your eyes moisturized and he althy.
Injury to the eye, for example from an accident, exposure to foreign objects or chemicals, recent surgery, overexposure to ultraviolet light, or burns, can cause red eyes.
This happens because the blood vessels in the eye dilate to allow more blood to flow to the site of the injury. If the blood vessels in the eye are injured, bleeding will occur.
If a foreign object accidentally enters and injures the eye, see a doctor immediately so that it can be treated immediately.
In addition to the conditions above, pink eye can also be caused by inflammation of the deeper layers of the eye, for example in episcleritis, scleritis, and uveitis. In addition, red eyes can also be caused by exposure to chemicals, such as tear gas.
Tips to Prevent and Treat Red Eyes
It has been mentioned before that pink eye is not a serious condition that needs to be treated immediately. In many cases, this condition can be prevented by maintaining good hygiene and avoiding factors that can trigger red eye, such as dust.
Here are some tips to prevent red eye that you can try:
- Wash hands with soap and clean water after contact with people with eye infections.
- Stop rubbing or scratching your eyes.
- Reduce activities that make your eyes tired and stay away from substances or particles that can irritate your eyes.
- Clean your face after using make-up, especially in the eye area
- Avoid wearing contact lenses for longer than recommended. For contact lens users, clean the lenses and replace the lenses according to the instructions on the package or the doctor's instructions.Do not use contact lenses while sleeping, and avoid using contact lens products whose quality and safety are not clear.
- Wash your eyes with clean water if your eyes get dust or foreign particles.
- Use special glasses, especially if you often go outside to protect your eyes from exposure to sunlight and dust.
Using eye drops is one form of treatment to relieve red eyes. After treatment, usually the red eye condition will gradually improve.
In addition, the treatment of red eyes also needs to be adjusted to the cause. If it is caused by a bacterial infection, treatment is carried out through the administration of antibiotics by a doctor. These antibiotics can be in the form of eye drops, eye ointments, or medications that are taken by mouth.
Treatment of red eyes due to allergies can be done by avoiding allergy triggers and using allergy relievers, such as antihistamines.
For red eyes caused by dry eyes, the use of artificial tear drops is the right choice. This drug can be purchased over the counter without a doctor's prescription. Use every 2-3 hours according to the instructions and how to use it is stated on the package or as recommended by the doctor.
If the symptoms of red eye are accompanied by pain, nausea, severe headache, impaired vision, or sensitivity to light, consult a doctor immediately for proper treatment.
