San Antonio is known for allergens at different seasons of the year. One common concern that we typically see revolves around cedar and oak, typically in the winter months. In the springtime, pollen, ragweed, and certain flowers can wreak havoc on our eyes. Our immune system is triggered by mold, pollen, and even pet dander. This results in red, watery, itchy eyes. Therapeutic relief can come from prescribed medication to control your eye allergies.
