Watery eyes/tearing are usually due to allergies, infections and/or dry eye. Allergies can cause your eyes to appear inflamed and red (sometimes confused with ‘pink eye’) which can result in excessive watering and itching. Similarly, viral infections can also cause watery eyes/tearing whilst the infection is active. Surprisingly, dry eye can also cause watery eyes/tearing due to an unstable tear film. This can trigger your eyes to produce more tears to compensate but often the instability in the tear film prevents a proper equilibrium from occurring, thus leading to continuous watery eyes/tearing. If you are experiencing watery eyes/tearing, visit an optometrist for a proper dry eye diagnosis and treatment.
