Tears are a mixture of water, mucus, and, oil, and serve an important purpose in eye health and function. Tears keep your eyes lubricated, protect them against infections, and wash away dirt and debris so you can enjoy clear vision.
Without quality tears, your eyes may burn or sting, get red and itchy, or feel gritty or fatigued. These are common symptoms of dry eye. Dry eye can blur your vision or make your eyes more sensitive to light and glare. You may find it difficult to read, watch TV, sit at your computer, or wear contacts for any length of time.
Although dry eye is more common in seniors, it can occur in anyone at any age, especially people who overuse or don’t take proper care of their eyes.
