What Causes Ocular Allergies?

Ocular allergies are adverse immune responses when the eyes interact with an irritating substance. These substances or allergens make the eyes red, watery, and itchy. The immune system mistakes allergens for bacteria and viruses.

It creates chemicals to fight the allergens, resulting in inflammation and numerous irritating symptoms. To avoid ocular allergies, you need to know what causes them; here are a few of those causes.

Dust

It is the most common cause of ocular allergies. It is everywhere and very hard to avoid. It is worse where there is a lot of traffic, gardening activities, or playing field sports. Protect your eyes and prevent allergens from triggering your eyes. Also, remember to wash your hands when you are through with your activity or when you remove your eyewear.

Mold

Mold is sometimes present in houses. However, it is common in gardens and areas with trees. If you are a gardener, you cannot avoid touching mold occasionally. But if you take a walk in the park, avoid mold. Also, wear sunglasses to avoid getting this allergen in your eyes. If you happen to touch it, do not touch your eyes and wash your hands as soon as possible.

Ragweed and Pollen

Ragweed may only last for a season, but it produces billions of pollen. It is present during field sports, construction, and gardening. These can stir up some pollen from ragweed. In other seasons, pollen may come from other plants.

To avoid irritation, remove the clothes you are wearing and clean up immediately once you get home. Make sure you do not put your clothes on the bed as some allergens may get on your pillow. When they do this, they will irritate your eyes as you sleep.

Smoke

This allergen affects almost anyone who encounters it. It causes tears, redness, and irritation of the eyes. If you know you may interact with smoke, wear eye protection. If you come by it without preparation, be careful it does not get into your eyes.

Medication, Cosmetics, and Perfume

Medication can cause ocular allergies when you ingest it. Cosmetics and perfume may contain chemicals that may cause ocular allergies when you inhale or apply them. If you notice any reaction with these substances, discontinue their use immediately and seek medical attention.

Some eye drops may also irritate your eyes due to the preservatives in them. It is why you need to seek medical attention first if you react to any substance before self-medicating.

Insect Bites or Stings

Sometimes, insect bites or stings may cause a reaction in your body that affects your eyes. When this happens, try and note which insect it is even as you seek medical attention. Knowing the type of insect will help the medic. For example, bee stings are acidic, while wasp stings are alkaline. This informs them which first aid to administer.

There are many other causes of ocular allergies. These include food, dust mites, and even household chemicals. If you know you have allergies, set a plan to mitigate them.
