When you think of the word “windshield,” you probably focus on automobiles. If so, you might want to expand your definition of the word to include sunglasses that block the wind, especially if you suffer from dry eyes. The fact is that very nearly half (48%) of American adults, including 52% of women, suffer from occasional dry eye symptoms. Chronic dry eye (dry eye syndrome) affects 7.8% of women over age 50. If left untreated, dry eye syndrome can lead to infection and even loss of vision. To avoid these problems, it is important to augment and preserve the oily substance (meibum, produced by 30-40 meibomian glands on the rim of each eyelid) that prevents tears from evaporating. If your eyes do not produce enough tears, you may experience stinging, scratchiness, or excessive eye irritation from smoke or wind. As with any vision problem, early detection and treatment of dry eyes can help prevent infection. Without sunglasses to protect the eyes from oncoming wind, tears evaporate faster while also reducing tear production and increasing inflammation.
