We welcome Dr. Han to our blog with his first post on allergies and your eyes.
It’s the time of the year when the sun is out and just about everything is in full bloom. It’s also a great time to be outdoors. Why shouldn’t we take advantage of what nature has to offer? For many of you, the answer is simple: allergies.
A stroll through the park or a bike ride down the street is a great way to enjoy the sunshine. Unfortunately, even a walk down the driveway is often all it takes to encounter pollen and other allergens. To fully enjoy the outdoors during this time of year, you must first understand how our body responds to allergens and learn how to properly prepare ourselves for outdoor activities.
Within the skin and soft tissue around the eyes are mast cells. Mast cells contain many smaller histamine cells. When mast cells detect something they don’t like or recognize, they burst and release the histamine cells. These cells bind to receptors in the skin, which triggers itching, redness and swelling—an allergic reaction. Many common allergy medications are histamine blockers that prevent this reaction from occurring. You can purchase these over the counter from your pharmacist. Other, more effective allergy medications have a mast cell stabilizing capability in addition to histamine blockers. These are the prescription medications that your optometrist can prescribe to you.
