Eye moisture is crucial to healthy eyes. Without adequate moisture, the eyes can experience a number of unwanted symptoms. One of the chief concerns of dry eyes is an increased risk of eye infection. The eyes’ natural tears prevent bacterial colonization. Removing the tears allows bacteria to grow unchecked. Common symptoms of dry eyes include itchiness, stinging, and burning. Your eyes can develop sensitivity to light and may become red. They may be watery more than normal, which is a response to dryness. You may also experience the feeling of a foreign object in your eye when there isn’t one.
