Many people worldwide suffer from the condition called dry eyes. It is a syndrome which occurs when the eyes do not produce enough tears or simply when the tears evaporate too fast. This usually causes the eyes to dry out completely and become swollen, irritated and that is the moment when the discomfort hits, followed by pain and occasional blurry vision. It is like something is stuck in your eye all the time, every day. If you are a person who enjoys running or cycling, this syndrome can cause severe problems for you.
