Allergic Shiners: A Not-so-shiny Sight
A dark circle under the eye is usually a sign of exhaustion or a fight. However, this is also a symptom of allergies. Allergic shiners are also called allergic facies or periorbital venous congestion/periorbital hyperpigmentation. While the discoloration is harmless, having it or seeing it on someone can be very worrisome.
What causes allergic shiners?
Allergic shiners are caused by the pooling of blood under the eyes, due to the swelling of the tissue in the nasal cavities. When the sinuses are blocked, nothing around the face drains well. Therefore, when there is congestion, the blood that usually flows freely through the capillaries under the eyes to the heart, pools, creating dark circles and sometimes puffiness. This combined with itchiness caused by allergies could make your eyes look so irritated.
Common allergens that can cause allergic shiners include dust mites, pet dander, mold and fungus, pollen, and cockroach feces.
Differences to black eye
- With allergic shiners, the blood has difficulty draining from the facial veins due to swelling
- Black eyes are due to trauma and involve bleeding under the skin caused by damaged capillaries
- Allergic shiners are usually accompanied by other nasal allergy symptoms
Other causes of dark circles under the eyes include lack of sleep, dehydration, too much salty food, iron deficiency, aging, and eczema, among others. People may also inherit genes that cause the skin under their eyes to appear darker.
Treating allergic shiners
The key to not getting allergic shiners is to reduce congestion in the nasal and sinus cavities. There are also many over-the-counter treatments to treat allergies that cause allergic shiners which include antihistamines, decongestants, nasal steroid sprays, and anti-inflammatory eye drops. Never take medications that are not prescribed by the doctor.
