Understanding dry eyes

Dry eye affects a lot of people. To better understand, let's see its causes, definition and why the Tear film is important for our eyes.

Dry eyes happen when our eyes don't make enough tears or when they evaporate quickly. This can cause discomfort, red eyes, and blurred vision. Approximately 30% of Canadians have this problem, which shows its importance.

Composition of the tear film

The Tear film is crucial for our eyes. It has three layers:

• Lipid layer: protects against evaporation
• Watery layer: moisturizes and nourishes the eye
• Mucinic layer: helps to distribute tears evenly

Importance of tears for eye health

Les lacrimal glands produce tears that are essential for our eyes. They lubricate, protect against infections and moisturize the cornea. Tears contain water, salt, oil, glucose, and protein. The blinking of the eyelids distributes these elements evenly.

A good functioning lacrimal system is crucial. This helps to avoid dry eyes and ensures clear and comfortable vision.

Prevalence and impact of dry eye

Dry eye affects more than one in three Canadians. This is a major reason for consultation in optometry and ophthalmology. Women, especially after menopause, are more affected.

Age and gender factors

Aging is a major factor in dry eyes. With age, tear production decreases, increasing the risk of dryness. Women, especially after menopause, are at greater risk due to hormonal changes.

Environmental conditions

The environment can strongly influence the eye health. Air conditioned spaces, windy areas, and air pollution are risk factors. These conditions accelerate the evaporation of tears, disrupting the natural balance of the eye.

Modern lifestyles

Our current lifestyles play a role in dry eyes. Prolonged use of screens reduces the frequency of blinking, promoting the evaporation of tears. Wearing contact lenses can also interfere with the natural tear layer.

Diseases and medical conditions

Certain autoimmune conditions, such as Gougerot-Sjögren syndrome, cause dry eyes. Antidepressants or antihistamines may also reduce tear production. Laser refractive surgery can cause temporary or permanent dry eyes.

Understand these risk factors is essential for taking care of your eyes. A consultation with an ophthalmologist can help identify specific causes and develop an appropriate treatment plan.

Types of dry eyes

Dry eye is a complex problem with many forms. It is important to understand these types in order to better deal with them.

This type of dryness is characterized by insufficient tear production. Les lacrimal glands do not produce enough liquid. This causes burning and irritation.

Lipid layer deficiency

The lipid layer deficiency comes from the Meibomian glands. These glands don't produce enough lipids. These lipids prevent the rapid evaporation of tears. Without them, the eyes dry up quickly, even with normal tear production.

Mixed type

The mixed type combines the previous two. It is the most common form of dry eye. It is characterized by insufficient tear production and excessive evaporation. This type often requires more complex treatment.

Each type of dry eye requires a specific treatment. An accurate diagnosis is crucial in choosing the best treatment. It helps to relieve symptoms effectively.

Aggravating risk factors
