Eye allergy is a fairly common eye disease, especially in the hot and humid climate in our country. The right treatment will help you improve the allergy in your eyes.

1. Allergic skin around the eyes

Allergies to the skin around the eyes, conjunctiva, also known as blepharitis, allergic conjunctivitis, occur when the eyes react to irritants. These substances are called allergens, and when the body reacts to them, it causes an allergic reaction.
The immune system protects the body against harmful external factors such as viruses and bacteria, helping the body not to get sick.
However, when the immune system overreacts, it causes immune reactions to substances it considers dangerous in people with eye allergies. The immune system produces chemicals that fight the allergen, even though these substances are harmless.
Allergic reactions lead to many unpleasant symptoms such as itchy eyes, red and watery eyes, no discharge, eyelid edema, conjunctival edema. In some people, eye allergies can also be linked to eczema and asthma.

2. Eye allergy treatment

The key to the treatment of eye allergies is to avoid or limit exposure to the allergen, and the patient must often know what to avoid. If necessary, an allergist can perform skin tests or blood tests to help identify specific allergens.
2.1 Avoiding allergens If pollen is an allergen for you, avoid going outside as much as possible when pollen counts are highest (usually between morning and evening) and when the wind is blowing pollen around around. When you're outdoors, sunglasses or eyeglasses can help prevent pollen from getting into your eyes.
To help reduce your exposure to pollen and other irritants while you're inside, close your doors and use air conditioning - both in your car and home. Do not use exhaust fans, as they draw pollen and other allergens inside. Keep air conditioning units clean so they don't cycle allergens inside.

If dust in your home is causing your allergic conjunctivitis, try to limit your exposure to dust, especially in your bedroom. Cover your bed with allergens - especially your pillow - to keep dust from coming into contact with your skin. Wash your bedding regularly, using hot water that is at least 60 degrees Celsius. When cleaning your floors, instead of using a broom or dry duster, use a damp rag or towel to prevent substances. cause allergies.
If pets are a source of allergies for you, try to keep animals outside of the house as much as possible. Keeping pets out of the bedroom so you can sleep in an allergen-free room is especially important. Consider hardwood or tile floors instead of carpet, to prevent pet dander. Always wash your hands after touching a pet and wash clothing that has been in contact with the pet.
