Dry eyes are one of the common causes for red and bloodshot eyes. When your eyes are dry they become irritated and inflamed, and inflammation causes redness. Dr. Svetlana Fisher of Specs Appeal Optometry says that while dry eyes are often caused by a dry climate, they can also be caused by looking at a computer screen for too long. Dr. Fisher recommends using artificial tears to help with dry eyes. Also try these home remedies for dry and irritated eyes.
“Many people are not aware that their household pets can cause bloodshot eyes,” says Dr. Fisher. She says that getting them groomed often and keeping their hair short can help with preventing your eyes from getting itchy and inflamed. Other allergies that cause bloodshot eyes are seasonal allergies and dust. Always make sure to keep your house clean, especially during seasons where there is a lot of pollen in the air. Another tip that Dr. Fisher recommends is changing out your carpets for hardwood floors. Beyond inflammation, allergies can also cause you to have watery eyes. To help, try applying a cold compress to your eyes multiple times a day or eye drops specifically for allergies.
