If you’ve been buying artificial tears at the drugstore for six months and your eyes still burn by mid-afternoon, you don’t have a tear deficiency. You have an inflammation problem, a meibomian gland problem, a screen-time problem, an Omega-3 problem, or some combination of all four. Chronic dry eye is one of the most under-diagnosed conditions in eye care — and the over-the-counter aisle is the wrong place to solve it.
What is actually dry?
Your tear film has three layers: a mucin layer (which sticks to the eye), a watery layer (which carries oxygen and nutrients), and an oil layer (which keeps the watery layer from evaporating). Most chronic dry eye is not a deficiency of the watery layer — it’s a deficiency of the oil layer, secreted by the meibomian glands along your eyelid margin. Drops replace the watery layer. They don’t fix the oil. That’s why they wear off in twenty minutes.
The dry eye workup.
A real dry eye evaluation at Glimpse takes about 45 minutes and looks for the root cause:
- Tear breakup time (TBUT). We measure how long your tear film stays intact between blinks. Under 10 seconds is diagnostic.
- Meibography. We image the meibomian glands along your eyelid — you can see them on a screen. Atrophied glands tell us the oil is the problem.
- Osmolarity testing. A drop of tear film tells us how concentrated (and inflamed) your tears are.
- Lid hygiene assessment. Demodex, blepharitis, and lid-margin debris all drive dry eye — we look for all three.
What actually works.
Once we know which layer is failing, the menu opens up significantly:
- EyePromise EZ Tears — an oral supplement with eight anti-inflammatory ingredients that addresses systemic inflammation rather than topical symptoms. Relief in 1–2 weeks for most patients.
- Optase Dry Eye Intense Drops — preservative-free hyaluronic acid drops with significantly longer dwell time than the drugstore brands.
- Heyedrate Hypochlorous Spray — a daily eyelid mist that targets demodex and blepharitis at the lid margin.
- OPTASE Heat Masks — warm compress therapy to express the meibomian glands.
- Prescription Restasis or Xiidra — long-term anti-inflammatory drops we prescribe when the workup justifies them.
- Low Light Therapy — our in-office photobiomodulation device specifically targets meibomian gland dysfunction.
What to do this week.
If you’ve been using artificial tears for more than 90 days and you’re still symptomatic, stop buying drops at the drugstore and schedule a dry eye evaluation. We’ll look at the actual cause, build a plan, and almost always get you to relief within a month. Drops have their place — but they’re a treatment, not a diagnosis.
