Dry Eye Diagnosis 101

All About Eyes Protecting Your Eyes

What Your Optometrist Is Really Looking For

What Is Dry Eye Disease?

Dry eye disease happens when your eyes don’t produce enough tears, or when your tears evaporate too quickly, resulting in a dry, irritated, sometimes watery eye surface that doesn’t feel or function the way it should.

There are two main types:

  • Evaporative dry eye: Most common. Caused by blocked oil glands (called meibomian gland dysfunction or MGD) that prevent your tears from staying on the eye.
  • Aqueous-deficient dry eye: Your tear glands aren’t producing enough fluid to keep your eyes moist.

This condition affects millions of adults and can worsen with age, excessive screen time, or contact lens use.

How Is Dry Eye Diagnosed?

There’s no single “yes or no” test for dry eye. Your optometrist uses a combination of tools to assess your symptoms and tear film health.

Common tests include:

  • Tear Break-Up Time (TBUT): Measures how quickly your tears evaporate.
  • Schirmer’s Test: Gauges how much fluid your eyes produce.
  • Ocular Staining: Special dyes highlight dry or damaged spots on the eye.
  • Meibography: Imaging to view the structure and function of your oil glands.
  • Tear Osmolarity: Measures how “salty” your tears are — too much salt signals instability.
  • Inflammation Marker Tests (MMP-9): Detects inflammation in the tear film.
  • Symptom Surveys: Questionnaires help track how dry eye affects your comfort and daily life.

What Is Your Optometrist Looking For?

Your doctor is trying to pinpoint three key things:

  1. What type of dry eye do you have? (Evaporative, aqueous-deficient, or both)
  2. How severe is it?
  3. What’s causing it? (Blocked glands? Inflammation? Medication side effects?)

This combination helps build a personalized treatment plan.

How Is Dry Eye Treated?

Dry eye therapy is often a multi-step treatment. You may start with basic care at home and progress to prescription drops or in-office procedures, depending on the severity.

  1. At-Home Basics
  • Artificial Tears: Choose preservative-free options if you plan to use them multiple times daily
  • Warm Compresses: Help loosen blocked oils in your eyelids
  • Eyelid Cleansing: Use wipes or foams to reduce debris and bacteria
  • Environment Adjustments: Use a humidifier, avoid ceiling fans, and take screen breaks
  1. Prescription Therapies
  • Anti-inflammatory drops: Like Restasis, Cequa, or Xiidra
  • Nasal spray (Tyrvaya): Stimulates natural tear production
  • Oral meds: Like doxycycline for MGD or omega-3 supplements.
  1. In-Office Procedures
    • LipiFlow®: A 12-minute treatment using heat and gentle pressure to clear meibomian gland blockages.
    • IPL (Intense Pulsed Light): Reduces eyelid inflammation and improves gland function. Often done in a four-part series 
    • Trilift and Microneedling: TriLift uses Dynamic Muscle Stimulation and Radio Frequency to tighten the eyelid and facial structures for better blinking and lid closure while sleeping, microneedling restructures the tissue as well as addresses fine lines and wrinkles.
    • ZEST: Specialized antimicrobial solution to eliminate demodex mites, reduce inflammation, and relieve the itching and irritation of demodex blepharitis.
    • Rinsada: Irrigating lid retractor that delivers a pressurized sterile flush to cleanse the inner eyelid tissues, removing irritants and biofilm to provide immediate and lasting relief from dry eye and other ocular surface conditions.
  • Mibo Flo: A handheld thermoelectric device that delivers consistent, therapeutic heat to the eyelids to gently liquefy hardened meibum and improve meibomian gland flow. Performed with manual expression to restore natural oil production and stabilize the tear film.
  • Low-Level Light Therapy(LLLT): Uses controlled LED light energy to reduce inflammation, improve cellular function, and support healing of the eyelids and ocular surface. Often combined with other dry eye treatments to enhance gland performance and long-term symptom relief.
  1. Advanced Therapies
  • Scleral Lenses: Custom lenses that hold moisture against the eye — ideal for severe dry eye or autoimmune conditions.
  • Autologous Serum Drops: Made from your own blood — used for severe cases when other treatments fail.
