What Are the Symptoms of Dry Eye?

Dry eye is one of the most common conditions eye doctors see — and one of the most misunderstood. Here's what's actually happening in your eyes, and how to recognize it early.

What Is Dry Eye?

Dry eyes are caused by a variety of factors that disrupt a healthy tear film. Your tear film is made up of three layers — fatty oils, aqueous fluid, and mucus — that work together to keep the surface of your eyes lubricated, smooth, and clear.

For some people, this process doesn't provide enough lubrication, and dry eye develops. The tears produced can be inadequate for many reasons, but the end result is the same: tear instability that leads to inflammation and damage of the eye's surface.

1
Lipid layer

The outermost, oily layer formed by the meibomian glands. It prevents tear overflow, slows evaporation, and lubricates the eyelids when you blink. Dysfunction here causes evaporative dry eye.

2
Aqueous layer

The middle layer and the bulk of the tear film, secreted by the lacrimal glands. When these glands don't secrete enough, dry eye follows.

3
Mucin layer

The innermost and thinnest layer, made of goblet and epithelial cells. It allows the aqueous layer to adhere evenly to the cornea's surface.

Common Symptoms

Dry eye symptoms are often easy to notice once you know what to look for:

Stinging or burning Light sensitivity Discharge or mucus Redness Watery, irritated eyes Blurred vision

Two Types of Dry Eye

Not all dry eye is the same — the two main types are caused by different breakdowns in the tear film.

Type 1
Evaporative dry eye

Tears evaporate too quickly, usually because the meibomian glands — the oil-producing glands of the eyelid — aren't working properly and can't slow tear evaporation the way they should.

Type 2
Aqueous-deficient dry eye

The lacrimal glands don't produce enough of the watery, aqueous component of tears — the layer that makes up the bulk of the tear film.

At-home prevention
  • Use over-the-counter eye drops
  • Take regular breaks during prolonged screen use
  • Avoid exposure to smoke
  • Use artificial tears regularly
  • Practice conscious, full blinking
  • Apply a warm compress to the eyes
