Practice good makeup hygiene. Makeup worn on and around the eyes, particularly mascara, can be a breeding ground for bacteria. If you want to ensure that your eyes stay clear and free from infection, take a few precautions. Mascara should be tossed after three months. In addition, avoid putting liner inside of the eyelash. This can block the oil glands necessary to keep your eyes protected.
See an optometrist. As you get older, your eyes do not work as well as they once did. You may not have needed glasses your entire life, but its a good idea to see an optometrist every year, the same as you see a dentist every few months. An optometrist will be able to tell you how your eyes are doing, and you can get glasses if necessary.
