One of the most common reasons for watery eyes is conjunctivitis. This is an irritation or infection of the conjunctiva, or the white area of the eye. In such occasions, a typical symptom besides watery eyes is a very visible red coloration. Doctors differentiate between infectious and non-infectious variants. Infectious conjunctivitis is caused by a virus or bacterium, while causes of the non-infectious conjunctivitis include allergies, irritation from very bright light, foreign particles or chemicals. In both cases you are advised to contact an eye care professional urgently and describe the symptoms. Since the illness is infectious, you should receive an appointment quickly.
Antibiotics help with bacterial infections. Otherwise, it is usually sufficient to avoid the triggers. An extra tip: in order to dry your watery eyes, you should use tissues. It is also advisable to wash your hands regularly. In this way, you can prevent the infection from being transmitted. In addition, people who have been infected should avoid wearing contact lenses; they should instead wear their glasses.
Another common cause of watery eyes is a poorly corrected vision problem, which causes the eye to work much harder in order to be able to see properly. Optimal and individually customized prescription eyeglass lenses, such as the ZEISS Progressive Individual 2 lenses, can be very helpful.
Watery eyes are also sometimes caused by a poor composition of the tear fluid. In addition to a large amount of water, our tears are also composed of proteins and a protective lipid layer on the upper layer of the tear film. The result is that the tear film does not adhere properly to the surface of the eye and drains off downwards. In such a case, your eye care professional can help with special drops.
Other possible causes for watery eyes are injuries to the surface of the cornea from foreign particles or scratches. The body responds to such injuries by producing significantly more tears. Also, some people’s eyelids may be improperly positioned. Experts speak then of an entropium, a downward-turning eyelid, or an ectropium, an upward-turning eyelid. Depending on the severity of the problem, a corrective operation may be required.
