Allergies are a problem for lots of people, close to 50% of the U.S. population suffers from allergies. To compound this, up to 60% of allergy sufferers experience eye symptoms as well. That means 80-100 million people have red, itchy eyes for part or all of the year. In warmer, southern climates like Texas, allergy season isn’t a season, it’s a way of life. Temperatures are generally warm enough year round to allow the growth of some kind of allergen.
Your genetics can predispose you to allergies. Those with relatives who are sensitive to things like ragweed and pet dander are more likely to suffer themselves. Some allergies are developed over time and gradually reach a point where they are bothersome. A move to a different climate can expose you to a new allergen, or just more of one that hits a threshold to bother you.
Redness and watering can be symptoms of other eye conditions such as conjunctivitis, dry eye or contact lens irritation. Itching is the main symptom that can help differentiate the cause of the irritation. Allergies cause a release of histamine that leads to itching and swelling of blood vessels (redness).
Steps to reduce allergies:
- Avoid the offending substance – This is often easier said than done. Be sure to keep your living space clean and free of dust and pet dander. Feline dander (fel d1) is present in 99% of homes, even in homes that do not have a cat.
- Use beauty products that are hypoallergenic and free of scents. This is especially true of cosmetics that are used around the eye.
- It could be your contact lens solution – Some people are allergic to the preservatives used in contact lens solutions. Try switching to a different brand. Even if you have used the same solution for years it is possible to develop an allergy over time.
- The same goes for eye drops – most commercially available eye drops contain preservatives that may be causing your reaction. It is important to speak with your eye doctor to help narrow down what may be the cause. Try using non preserved artificial tears (NPAT).
- Clean your contacts regularly – Contact lenses can shield your eyes from dust and pollen, but they also trap the particles and can make them harder to wash away. Certain lens materials attract more debris and form deposits easier. Make sure to clean your contacts regularly and replace them according to the schedule your doctor has recommended.
