It is a disease of tears and ocular surface of the eye. Tears are the main source of nourishment to the ocular surface of the eye. Tears are made of compounds that keep the eye moist and clean. If the production of tears in the eye is less or if the chemical composition of the tears are altered so that they evaporate quickly, leads to dry eye syndrome
Causes Of Dry Eye Syndrome

- Medicines like certain antihypertensive, Parkinson’s disease medication, antidepressants may cause lesser production of tears
- Living condition e.g. if you live in dry and humid climate or your office or home has dry heating systems
- Insufficient blinking. This can occur when person works for longer hours on computer Wearing contact lenses for longer period

Symptoms Of Dry Eyes

- Sometimes watery eyes can also result since dry eyes causes overstimulation of tear glands that leads to overproduction of tears

Treatment Of Dry Eyes
- The dry eye syndrome is an ongoing condition and is generally not completely curable. However the symptoms of the conditions can be treated
