Tears play an important role in keeping our eyes healthy. It helps wash away particles that enter the eye. Failure to maintain a healthy tear film results in dry eye syndrome. The common factors that can cause the development of this eye ailment are dry environment and certain activities.
Environmental factors can have a drying effect on your eyes, causing your tears to evaporate. These include: sun, wind, dry climate, hot blowing air, high altitude. Certain activities can also contribute to dry eye syndrome, such as: reading, writing, working with a computer. People tend to blink less frequently during activities that require visual concentration. This means the tear film evaporates or drains away more quickly than it’s replenished.
Ceiling fans, air heating systems, and air conditioners decrease the humidity in a room and can speed up evaporation, causing dry eye symptoms to develop. Prolonged computer or cellphone use is also a common trigger to dry eye syndrome. Experts advise frequent blinking of the eyes. During pregnancy and menopause, women experience hormonal changes, which may increase their risk of having dry eyes.
For the treatment of this common eye ailment, you must consult your physician. However, artificial can be bought over the counter without any prescription. Other treatments may include taking antihistamines, wearing glasses, and increasing your omega-3 supplements.
Eye drops, or artificial tears, can bring you temporary relief. Keep in mind that some eye drops contain preservatives. These usually come in multidose vials and contain preservatives to prevent bacterial growth once a vial is opened. If your eyes react badly to drops with preservatives, or if you apply eye drops more than four times a day, you should use preservative-free drops. Preservative-free drops usually come in single dose vials. Ointments are thicker than drops and are designed to coat the eyeball and provide longer-term relief from dryness.
