Dry Eye Syndrome, termed keratoconjunctivitis (KCS) refers to dry eyes that irritate you constantly. This annoying condition is due to insufficient production of tears or a poor quality tear composition. When your eyes aren’t lubricated well, you’ll suffer from the sensations of scratchiness, burning, watery eyes, blurred vision and/or a feeling of something gritty stuck in your eyes. The particular cause of dry eyes varies from person to person, and effective dry eye treatment is therefore also highly individual – depending upon the cause.
