What causes eye color

Inflammation of the eyes

Conjunctivitis is one of the most common eye diseases: Children in particular are often affected. But this is only one form of eye inflammation, because the eye consists of various components that can become infected. Depending on which eye component is inflamed, different forms of eye inflammation can be distinguished. The cause of this unpleasant eye problem are mostly viruses and bacteria, but also allergies or diseases such as rheumatism.

Eye inflammation: symptoms

The symptoms of eye infection are similar to those of dry eyes. These include:

  • Redness of the eyes
  • itching
  • Burn
  • Foreign body sensation
  • Increased flow of tears
  • Conjunctival swelling
  • Small bulges of the conjunctiva (follicle) (especially in viral or bacterial conjunctivitis)
  • Photophobia

Possible causes of an eye infection

  • Viruses, bacteria, fungi
  • Dry eyes
  • Foreign body in the eye
  • Contaminated or damaged contact lenses
  • Allergies (e.g. hay fever, animal hair)
  • Diseases (e.g. rheumatism)

Eye infections can have a variety of causes, but the main ones are clearly bacteria, viruses, and fungi. Our eyes are exposed to these pathogens and environmental stimuli every day. If the eye's defenses are overloaded, the viruses and bacteria gain the upper hand: Then an eye infection develops. Unlike conjunctivitis, which is caused by an allergic reaction, infectious conjunctivitis is contagious.

Dry eyes are particularly prone to eye infections. This is because the tear film is disturbed when the eyes are dry. Then the immune defense of the eye only functions to a limited extent. The result: pathogens get into the eye more easily and cause unpleasant inflammation.

Aside from viruses, bacteria or dry eyes, allergic reactions such as dust mites, pollen or animal hair can also trigger eye infections. Other causes of eye inflammation are also environmental stimuli such as drafts, sunlight or dust particles. Mechanical stimuli such as an eyelash that has grown into the eye or other foreign bodies can also inflame the eye.

Inflammation can affect many parts of the eye. You can find the most common ones below.

Inflamed eyelids


Skin bacteria spread particularly quickly in the eyelids and often lead to painful inflammation in the eyelid. If you rub your eyes constantly - for example due to unpleasant dust particles or pollen - it makes it easier for bacteria to get into the corresponding eye area and spread there. Once the eyelids are inflamed, the eyelid is often reddened or swollen.

Do you have a painful, red lump on your eyelid? Then it may be a so-called one Barley grain (hordoleum). This is a bacterial inflammation on the eyelid or the eyelid gland. That too Hailstone (chalazion) is one of the eyelid inflammation. The hailstone is caused by a blockage of the meibomian gland.

With regular and correct eyelid margin care, you can avoid eye problems such as inflamed eyelids, stye and hailstones, or at least alleviate their symptoms.

Inflamed conjunctiva (conjunctivitis)


The most common form of eye inflammation is inflamed conjunctiva. The conjunctiva is most frequently affected, especially in the context of bacterial eye infections. The conjunctiva can also become inflamed due to viruses, germs or allergies. External stimuli such as chlorine or dust can also cause conjunctivitis.

An inflamed conjunctiva usually manifests itself with reddened and watery eyes. In addition, the eyes can be festering and sticky. If the conjunctivitis is caused by adenoviruses, it is called eye flu. Characteristically, there are also flu-like symptoms such as fever, headache and body aches.

Inflamed iris


The iris, also called the iris, is the part of the eye that determines our eye color. Affected one Irisitis(Anterior uveitis) mostly suffer from dull pain around the eyes and forehead. Just like conjunctivitis, the iris can become inflamed due to bacteria and viruses.

Inflamed outer skin of the eye


The outer skin of the eye includes both the cornea and the dermis. Both can catch fire. A Inflammation of the cornea (keratitis) in most cases caused by bacteria; Viruses and fungi are extremely rarely the trigger for corneal inflammation. Contact lens wearers in particular have an increased risk of corneal inflammation. The Dermatitis(Scleritis) is usually limited to only a small part of the dermis. This is mostly triggered by stress and manifests itself with reddening of the eyes.

Treatment of eye inflammation: what helps?

Moisturizing eye drops or ointments help regenerate the eyes. If your eyes are inflamed, Similasan can help. Compresses can also relieve the symptoms of eye inflammation.

Avoid - if possible - contact lenses and cosmetics in the eye area so as not to irritate the eyes even more.

Similasan advises against douching or compresses with chamomile tea, otherwise there is a risk of an allergic reaction. In addition, the eyes can be irritated by the fine hairs of the chamomile flowers.
