Dry eye... but why?

What exactly is dry eye? It’s more than just the symptoms that you feel. It’s an underlying condition that can be caused by different things, and could mean you need a long-term treatment.

What’s causing your dry eye symptoms?

Do your dry eyes still feel gritty, rough, or tired no matter what you do? Do you experience vision that changes throughout the day?

There are 2 types of dry eye:

Too much tear evaporation

which contributes to dry eye in about 9 out of 10 people.

Not making enough tears

which is a less common type of dry eye.

Sometimes, you can have a combination of both types of dry eye.

With too much tear evaporation, it’s common to experience:

  • Closed eye icon

    Needing to blink to clear your vision

  • Blue question mark

    Vision that fluctuates

  • Clock icon

    Symptoms that get worse throughout the day

Why do my dry eyes feel watery?

Adding eye drops to eyes that are already watery may seem strange. But that watery feeling is a common symptom of dry eye. It can be a sign that your tears are evaporating too quickly, leaving your eyes without enough lasting moisture.

Dry eye disease

Expand all

  • Dry eye is more than just the symptoms that you feel. It’s an underlying condition that can be caused by different things. There are 2 types of dry eye. The first type involves your eyes not producing enough tears. This is called aqueous-deficient dry eye. The second type is when your tears evaporate too quickly. This is called evaporative dry eye. Too much tear evaporation is a leading cause of dry eye in about 9 out of 10 people with dry eye. In both types, these conditions can potentially result in symptoms that make your eyes feel tired, scratchy, gritty, rough, or dry. Evaporative dry eye can be driven by factors in our modern lifestyle, like screen time. Sometimes, you can have a combination of both types. MIEBO is the only prescription dry eye drop that directly targets too much tear evaporation to treat signs and symptoms of dry eye disease. No other water-based or water-free prescription drops directly target tear evaporation.

  • No, not all dry eye is the same. There are 2 types of dry eye:
    • Evaporative, or “too much tear evaporation,” which contributes to dry eye in about 9 out of 10 people.
    • Aqueous deficient, or “not making enough tears,” which is a less common type of dry eye.
    • Some people may have a combination of both types.
