Dry Eyes: Causes, Symptoms, and Effective Treatments

Dry eyes are a very common ocular problem affecting people of all ages. They occur when the eyes do not produce enough tears or when tears evaporate too quickly, causing discomfort such as itchy eyes, stinging, irritated eyes, or a feeling of eye strain.
Fortunately, there are effective treatments and dry eye drops that help relieve symptoms and improve daily eye comfort.

What are dry eyes and why do they occur?

Dry eye syndrome occurs when the tear film fails to keep the ocular surface properly lubricated. This can be due to either a decrease in tear production or excessive evaporation, leading to persistent discomfort.

Causes and risk factors for dry eye

Lack of tear production

One of the most common causes of dry eyes is insufficient tear production, which can be related to various factors.

Aging and hormonal changes

With age, tear production naturally decreases. In women, hormonal changes associated with menopause can favor the appearance of dry and irritated eyes.

Autoimmune diseases

Conditions such as Sjögren's syndrome or other systemic diseases can directly affect the lacrimal glands, causing chronic dry eye.

Medication

The use of antihistamines, antidepressants, or blood pressure medications can reduce tear production and increase the sensation of tired or dry eyes.

Excessive tear evaporation

Meibomian gland dysfunction

These glands produce the lipid layer of tears. When they don't function properly, tears evaporate more quickly, causing stinging eyes and irritation.

Environmental factors

Air conditioning, heating, wind, or dry environments favor tear evaporation and worsen the symptoms of irritated eyes.

Other associated factors

  • Prolonged screen use

  • Continuous contact lens wear

  • Previous eye surgeries

  • Blepharitis or eyelid abnormalities

Most common symptoms of dry eye

People with dry eyes may experience various symptoms, which vary in intensity:

  • Persistent itchy eyes

  • Burning or stinging eyes

  • Gritty sensation

  • Red and irritated eyes

  • Tired eyes, especially at the end of the day

  • Intermittent blurred vision

In some cases, excessive tearing may occur as a reflex response, although this usually does not relieve dryness.

How to effectively relieve dry eyes

Treatment for dry eyes depends on the cause and intensity of symptoms. In most cases, the first step is to use dry eye drops to help hydrate and stabilize the tear film.
