Why Dry Eye Isn't Always About a Lack of Tears

When people hear the term dry eye, they often assume their eyes simply aren't producing enough tears.

But dry eye disease can be more complicated than that.

Some people with dry eye actually experience excessive watering. Others have tears that evaporate too quickly, leaving their eyes feeling uncomfortable even though they appear watery.

Understanding why this happens is an important part of managing dry eye effectively.

Your tears do more than keep your eyes wet

A healthy tear film helps maintain a smooth, comfortable surface over the eye.

It contains different components that work together to protect and lubricate the ocular surface.

One important component is the oily layer produced by glands in the eyelids, known as the meibomian glands. This layer helps slow tear evaporation.

When these glands aren't functioning properly, the tear film may become unstable, contributing to irritation, fluctuating vision and other dry eye symptoms.

Why eye drops don't always solve the problem

Lubricating eye drops can provide useful relief, but they may not address every factor contributing to a person's symptoms.

For example, if tear evaporation is a major contributor, management may also need to consider eyelid health and meibomian gland function.

Other factors, including medications, environmental conditions and certain health conditions, may also play a role.

Different causes require different approaches

Two patients can describe very similar symptoms but have different clinical findings.

That's why we believe it is important to investigate the possible contributing factors rather than assume every patient needs the same treatment.

At Eyecare Plus Mermaid Beach, our approach is to listen carefully, assess the ocular surface and discuss management options based on each patient's needs.

The importance of understanding your eyes

If you've been using eye drops without lasting relief, it doesn't necessarily mean nothing else can be done.

A comprehensive assessment may help identify contributing factors and guide appropriate management.

Our goal is to help patients understand their eye health and make informed decisions about their care.
