Dry eyes: the role of tears
Dry eye is usually the result of a tear film abnormality. Tear production may be insufficient, its evacuation disrupted or its composition altered. However, tears play a fundamental role in the good health of your eyes.
Tears are composed mainly of water, but they also contain nutrients, mineral salts, enzymes, proteins, antibacterials and a lipid film which protect them from evaporation.
Your cornea is transparent. It is not vascularized. As a result, it is oxygenated and nourished by the elements dissolved in tears.
In addition to its nourishing role, the tear film also provides lubrication, immunity, prevents irritation and contributes to the optical properties of your eyes.
Tears play an essential role in maintaining a healthy ocular surface.
Dry eye: the causes
Why are there no tears?
Dry eye can have various causes, and it is important to know them to better prevent and treat this problem. The main causes are:
Age: The tear glands tend to atrophy over time, reducing tear production. Hormonal fluctuations, such as menopause or andropause, can also contribute to dryness.
The screens : the time spent in front of a screen is constantly increasing, especially among younger people. Fixation would reduce blinking by 30 to 50%, thus promoting the evaporation of tears.
The environment : atmospheric pollution, air conditioning or heating, pollen, tobacco smoke, etc.
Contact lenses: hydrophilic soft lenses absorb tears, much like a sponge, and can promote dehydration.
Certain diseases and certain treatments: this is why any feeling of dry eye should be reported to your GP or ophthalmologist.
