Red (Bloodshot) Eyes – Causes, Symptoms and Natural Remedies

Do you sometimes experience the unappealing red eye symptoms? When you look yourself in the mirror there it is: your eye is reddish and looks like it has blood in it. You may end up wondering why this happens and if the condition is serious.

What are bloodshot eyes?

Red eyes are nothing more than blood vessels that are dilated and swollen in your eyes. This condition usually is not serious, but may need your full attention.

When eyes need protection, sensitized mast cells start to release histamine that can cause redness and tearing. If this condition lasts for a while, it could cause long-term damage to surface of the eye.

What are the causes of red eyes?

There are many causes of red eyes. They can be divided into two major groups: external and internal.

External factors include:

  • Airborne allergens
  • Environmental irritants
  • Not having enough sleep
  • Viruses
  • Bacteria

Internal factors include more serious problems like:

  • Blepharitis
  • Conjunctivitis
  • Corneal ulcers
  • Scleritis
  • Acute glaucoma

Airborne allergens that could trigger bloodshot eyes include pollen, dust, animal dander, wind, dry air, sun, and many more. These allergens could make eyes not only red or bloodshot, but also itchy, burning, and watery. They even can cause swollen eyelids and produce a discharge.

Environmental irritants that can lead to bloodshot eyes include many chemicals such as most household detergents, swimming pool chlorine, pepper spray, etc.

How red eyes appear in the first place?

Sometimes our eyes needs protection from various irritants such as allergens and other environmental irritants. As mentioned earlier, small particles like pollen, dust, animal dander, wind, dry air, and sun can irritate eyes so they become red.

These external factors start to irritate eye cornea, which is the outer layer of the eye. Because of that in the eye cells start to produce and release histamine. Histamine is a monoamine that fights inflammation. But when it’s present for long time it could damage tissue.

What are the symptoms of red eyes?

There’re a lot of symptoms associated with red eyes. Depending on the underlying cause symptoms can be mild as just redness or serious like falling out of the eyelashes. Some of them include:

  • Burning sensation
  • Watery eyes
  • Itchy eyes
  • Itchy eyelids
  • Swollen eyelid
  • Thick or watery discharge
  • Foreign body sensation
  • Photophobia (light sensitivity)
  • Dermatitis (crusting or scaling of the eyelid skin)
  • Eyelashes falling out (typically associated with blepharitis)

How to get rid of red eyes?

In the majority of cases red eyes are not serious condition and will pass within days. Most people don’t need any medication for red eyes treatment. But in the case of serious condition that cause red eyes, visiting ophthalmologist is a smart thing to do.

Having said all that, it is important to relieve the discomfort and irritation that accompanies red eyes syndrome. There’re two medications that successfully resolve all these problems:

  • Eye drops that contain vasoconstrictors and
  • Artificial tears.

Vasoconstrictors are chemicals that temporarily constrict blood vessels of the eyes. However, once a patient discontinue use of vasoconstrictors, eyes may become even redder. So better solution is using artificial tears.

In cases where bacterial infection is cause of red eyes, for example with conjunctivitis, physician may prescribe antibiotics. You should give one to two weeks for the infection to pass when using antibiotics. Also, if you decide to take antibiotics, follow your doctor’s orders strictly and take the entire box in order to prevent bacterial resistance.

On the other hand, viral conjunctivitis are very contagious and harder to treat. Viral conjunctivitis is typically caused by adenovirus. The medicament that is good for treating viral conjunctivitis is topical ganciclovir. It is a combination of topical agent that contains betadine and low-dose dexamethasone.

Some other medication for red eye treatment include oral antihistamines, and pain relievers. Oral antihistamines prevent allergies. So they’re good choice for treating allergic conjunctivitis. In fact, antihistamines prevent histamine release. When there’s no histamine inflammation, irritation, and  red colour of the eye should vanish.

What are the natural ways for curing bloodshot eyes?

Warm compresses are very beneficial when treating bloodshot eye problems. Warmth is good for releasing pain, itching, and relax eye muscle. Although warmth dilates blood vessels and increase circulation and redness, it’s beneficial for removing other symptoms like burning sensation, itchy eyes, and itchy eyelids.

Also, dry compresses are beneficial for people with dry eyes and those who find their tears evaporate too quickly.

Moist warm compresses on the other hand are more suitable if you experience eye muscle pain.
