That prompts the lacrimal glands to produce so many tears that they overwhelm the eye's natural drainage system. Tear production tends to lessen with age, so dry eyes are more common in older adults. Some medical conditions and medications can also lead to dryness, as can a dry and windy environment. But the most common cause of dry eye syndrome is a chronic condition called keratoconjunctivitis sicca (KCS). People with this condition make tears, but the tears do not contain enough water. In addition to excessive tearing, symptoms of dry eye syndrome may include blurred vision, itchy eyes, or burning eyes.
