What Are Allergic Shiners?

A symptom of allergies that appear as dark circles under the eyes is allergic shiners.

You might be allergic to pollen.

One symptom of allergies that appear as dark circles under the eyes is called allergic shiners. These are also known as periorbital venous congestion or allergic facies. So, what causes these to appear in the first place and how is it treated?


What are Allergic Shiners?

As mentioned above, allergic shiners appear as dark circles under the eyes. These shadowy and dark pigments somehow resemble bruises and are caused by a congestion of the sinuses and the nose. Unlike bruises that are caused by physical trauma, allergic shiners are caused by an allergy.



Apart from the purple or blue tint appearing under the eyes, other symptoms associated with this condition include the following.

  • Cough
  • Congestion of Nose and Sinuses
  • Itchy, Red, or Watery Eyes
  • Itchy Throat
  • Runny Nose
  • Sneezing
  • Tiredness

A lot of individuals often mistake allergic symptoms as the start of a sinus infection, flu, or cold. However, one must take note that the symptoms of an allergy persist for two weeks or longer. Also, unlike an allergy symptom, infections and colds rarely cause a fever and body aches. The symptoms of an allergy vary in severity and may come and go depending on the exposure of the allergen as well as the time of the year.



As mentioned, allergic shiners are a result of nasal and sinus congestion. The resulting congestion leads to restriction of blood draining from both areas that cause the veins under the eyes to pool with blood and widen. However, what causes such congestion in the nasal cavities and sinuses?

One common cause of nasal congestion is allergic rhinitis. It is also called nasal allergy and occurs when the body’s immune system reacts to a foreign body like pet dander or pollen. The body treats these foreign bodies as if they were dangerous. Some of the common allergens that lead to allergic shiners include the following.

  • Cockroach Feces
  • Dust Mites
  • Fungus and Mold
  • Pet Dander
  • Pollen

Aside from foreign bodies, some individuals may also be allergic to food. Such food that commonly results in an allergy includes wheat, nuts, eggs, and dairy. Environmental irritants can also lead to nasal congestion. These may also cause worsening of an allergic reaction, and such irritants include tobacco smoke, perfumes or other fragrances, and air pollution.

The time of year is another constituent that heightens the risk of developing allergic shiners. Individuals with seasonal allergies would quickly notice that some of their symptoms are active and present during a particular time of the year. Such an occurrence can help them pinpoint the actual allergen that is responsible for their allergic shiners.

For example, if the allergic symptoms worsen during the early spring, then it likely suggests an allergic reaction to tree pollen. On the other hand, allergic symptoms that manifest during the summer or late spring indicate an allergy to grass pollen. Furthermore, allergies triggered in the fall season is a result of ragweed.



Treating allergic shiners is similar to treating an allergy. The treatment methods primary goal is to reduce congestion in the sinus and nasal cavities. Some of the options are as follows.

1. Antihistamine Medicines

These include over-the-counter medications such as loratadine and diphenhydramine. Such drugs significantly reduce the symptoms of an allergy.

2. Decongestant Eye Drops

Such eye drops include tetrahydrozoline and naphazoline that relieve watery and itchy eyes. Much like decongestant nasal sprays, eye drops used more than three days may cause an allergic symptom to return.

3. Decongestant Nasal Sprays

These sprays lessen the pressure and the swelling in the nasal airways. Such sprays include neo-synephrine and oxymetazoline. Again, like the eye drops, these sprays must not be used for more than three days as it may result in allergic symptoms to return.

4. Prescription Medications

Doctors usually prescribe stronger medications if the treatment options mentioned above fail to address the allergic symptoms. An example of prescription medication is montelukast. The drug lessens the inflammation which is a result of exposure to an allergen.

Also, the treatment options mentioned above may help manage and reduce the symptoms. However, the best treatment is to avoid the allergen causing the allergic symptoms.
