7 Common Causes of Dry Eye
- Holding Back the TearsWe all have natural tears that help keep our eyes smooth and clear, and protect them from infection. But when you have dry eye, you don’t have enough quality tears to lubricate the eye and keep it healthy. Either you don’t produce enough tears, your tears evaporate too quickly, or you have a problem or imbalance in the makeup of your tears, which includes layers of oil, water and mucus. It’s a chronic problem for many people, and there are a variety of common causes.
- 1. AgeA decline in the water (aqueous) component of tear production is a natural part of the aging process. By the age of 50, most people begin to experience some symptoms of dry eye.
- 2. Your EnvironmentWindy or smoky environments, as well as dry climates, can lead to tear evaporation and increase your chances of developing dry eye. Also, staring at a screen, such as a phone or computer, for a long period of time can cause symptoms because you tend to blink less often. Seasonal allergies may also contribute to dry eye.
- 3. Medications
- 6. MakeupSome ingredients in your makeup can be irritating to the eyes or aggravate already-dry eyes. These include ingredients that act as preservatives, stabilizers or anti-caking agents, as well as color additives, such as kohl. And the way you apply your makeup is also important. For example, applying eyeliner to the inside of your eyelid can block the oil glands that protect the cornea. Sleeping in your makeup, especially mascara, can also clog oil glands, so make sure to wash your face before bed to keep your skin and eyes healthy.
- 7. Vision ProblemsIf you wear contact lenses, you may also develop dry eye, especially after using contacts for a long period of time. Also, refractive eye surgeries, such as LASIK, can decrease tear production and lead to dry eye symptoms, though these are usually temporary.
