More Info

---

Eye allergies, also known as allergic conjunctivitis, are a common condition that occurs when the eyes come into contact with allergens such as pollen, dust mites, pet dander, or mold. Understanding the causes, symptoms, and safety measures for contact lens wearers is crucial for managing this condition effectively.


Causes of Eye Allergies
Eye allergies can be triggered by various environmental factors. Common allergens include:
1. Pollen: Trees, grasses, and weeds release pollen into the air, which can cause seasonal allergies.

2. Dust Mites: These microscopic organisms thrive in bedding, carpets, and upholstered furniture.

3. Pet Dander: Proteins found in the skin flakes, urine, and saliva of furry pets can provoke allergic reactions.

4. Mold: Mold spores can be found indoors and outdoors, especially in damp areas.

5. Cosmetics and Eye Drops: Some individuals may be allergic to ingredients in makeup or eye medications.


Symptoms of Eye Allergies
The symptoms of eye allergies can vary in severity and may include:
- Itching and redness of the eyes
- Watery or teary eyes
- Swelling of the eyelids
- Sensitivity to light
- A gritty or burning sensation in the eyes

Contact Lens Safety
If you have a history of eye allergies, you may wonder whether you can continue wearing contact lenses. Here are some considerations:
1. Material Sensitivity: Some individuals may be allergic to the materials used in contact lenses or the solutions used to clean them. If you experience discomfort, consider switching to hypoallergenic lenses or solutions.


2. Hygiene Practices: Maintaining proper hygiene is essential. Always wash your hands before handling lenses and ensure that your lenses are cleaned and stored correctly.

3. Consultation with an Eye Care Professional: If you have eye allergies, it is advisable to consult with an optometrist or ophthalmologist. They can recommend suitable contact lenses, such as daily disposables, which may reduce the risk of allergic reactions.


Relationship Between Allergies and Other Conditions
You mentioned a history of urticaria (hives) and whether it relates to your eye allergies. While urticaria and eye allergies can both be manifestations of an allergic response, they do not always occur together. It is possible to experience eye allergies without having other allergic reactions.

Allergy Testing
If you suspect that your eye allergies are related to specific allergens, you can request allergy testing. Blood tests can help identify specific allergens that may be causing your symptoms. This information can guide you in avoiding triggers and managing your allergies more effectively.


Severe Symptoms and Complications
In severe cases, eye allergies can lead to complications such as:
- Chronic Allergic Conjunctivitis: Prolonged exposure to allergens can cause persistent symptoms and discomfort.

- Corneal Damage: Severe itching and rubbing of the eyes can lead to corneal abrasions or infections.

- Vision Problems: In rare cases, untreated allergic conjunctivitis can lead to complications that affect vision.


Conclusion
In summary, if you have eye allergies, it is essential to manage your symptoms effectively while considering the safety of wearing contact lenses. Consult with an eye care professional to determine the best course of action, including potential allergy testing and appropriate lens options. By understanding your triggers and symptoms, you can take proactive steps to maintain your eye health and comfort. If you experience severe symptoms or complications, seek medical attention promptly to prevent further issues.
