What Are Eye Allergies
Eye allergies, also known as allergic conjunctivitis, happen when the eyes react to matter that irritate them. These substances are known as allergens, and it causes an allergic reaction, when the body responds to them.
This kind of allergic reaction causes, itchy, watery and red eyes. These symptoms can also occur along with skin allergies (eczema) and asthma.
Allergic conjunctivitis is unlike conjunctivitis, which is provoked by viruses and bacteria.
An eye allergy, also known as allergic conjunctivitis, is an unfavorable immune response that happens when the eye comes into contact with an irritating body. This substance is called as an allergen. Allergens may include dust, smoke or pollen.
The immune system generally protects the body against injurious invaders, such as bacteria and viruses, to keep off illnesses. In individuals with eye allergies, however, the immune system misunderstands an allergen for a dangerous substance. Even though it is harmless, this causes the immune system to create chemicals that fight against the allergens. The response leads to many irritating symptoms, such as watery, itchy, and red eyes. In some individuals, eye allergies may also be connected to asthma and eczema.
Medications you buy without a prescription can usually help relieve eye allergy symptoms, but individuals with critical allergies may need additional treatment.
What are the symptoms of eye allergies?
Symptoms of eye allergies may involve:
Itchy or burning eyes
Red or pink eyes
Scaling around the eyes
Swollen or puffy eyelids, especially in the morning
One eye or both eyes may be impacted. In some cases, these symptoms might be accompanied by congestion, sneezing or a runny nose.
What causes eye allergies?
Eye allergies are caused by a harmful immune reaction to precise allergens. Most reactions are activated by allergens in the atmosphere, like:
Generally, the immune system aids chemical changes in the body that help fight off injurious invaders, such as bacteria and viruses. However, in individuals with eye allergies, the immune system mistakenly recognizes a harmless allergen as a harmful intruder and begins to fight against it. When the eyes come into contact with an allergen, a substance called histamine is released. Histamine causes many unbearable symptoms, such as watery and itchy eyes. It can also cause a sneezing, coughing and runny nose.
An eye allergy may occur at any time of year. However, it is especially frequent during the fall months when trees, grasses, and plants are in bloom, summer and spring. Such reactions can also happen when a sensitive individual comes into contact with an allergen and rubs their eyes. eye allergy symptoms may also be caused due to food allergies.
Diagnosis of eye allergies
Eye allergies are best detected by an allergist, or someone who is an expert in diagnosing and treating allergies. Seeking an allergist is specifically crucial if you have other allergy-related symptoms, such as eczema or asthma.
The specialist will first enquire about your symptoms and medical history, including when they started and how long they have continued. They will then do a skin prick test to discover the suppressed cause of your symptoms. A skin prick test includes pricking the skin and putting small amounts of suspected allergens to see if there is a harmful reaction. A swollen, red bulge will signify an allergic reaction. This helps the allergist determine which allergens you are most sensitive to, allowing them to identify the best course of treatment.
