Dry Eye Syndrome

Dry eye syndrome occurs due to an imbalance in the eye's tear film. The tear fluid is made up of three things: oil, water, and mucous substances. Every time we blink, the tear fluid is distributed across the cornea, forming a film on the surface of the eye. This film moisturizes the eye, ensuring clear vision, protecting against dirt and infections, and providing nutrients to the eye's surface. When there is either too little water or the tear film composition is incorrect, it causes dry eye syndrome. This condition is typically due to either reduced tear production or increased tear film evaporation. In summary, dry eye syndrome negatively impacts the eye's tear film.

Dry eye problems can have various causes, but the most common one is age. As people get older, tear production decreases, and the composition of tears changes. Other factors that may cause dry eyes include indoor climate, such as air conditioning and computer use. When using screens, people tend to blink less, which can cause dry eyes. Certain types of medication, for example, blood pressure medication, antihistamines, and anti-depressants can also cause dry eyes. Health conditions like diabetes, arthritis, connective tissue diseases, and vitamin deficiencies can also lead to dry eyes. Women, especially during hormonal changes like menopause, may be more susceptible to dry eyes. Regardless of the reason, dry eye syndrome is a significant concern for those affected by it.
