Dry eye is a disorder of the tear film that compromises the lubrication and protection of the eye surface. The causes may be related to insufficient production or excessive evaporation of tears.
How it manifests itself
Symptoms include dryness, burning, itching, redness, reflex tearing and intermittent blurred vision. They often worsen in dry environments or with prolonged use of screens.
Why it occurs
It can result from environmental or hormonal factors, the use of contact lenses, or certain medications. Inflammation of the Meibomian glands also plays a significant role.
The role of the tear film
The tear film nourishes, lubricates and protects the surface of the eye. When it is unstable, the surface becomes irritated and discomfort occurs.
When to see a specialist
A consultation is useful if symptoms are persistent or affect your quality of life.
