The Real Problem
Most people with chronic dry eye have been told to use artificial tears and blink more. That advice is not wrong, but it is incomplete. Roughly 86 percent of chronic dry eye is evaporative — meaning the tear film cannot stay on the surface of the eye because the oil layer (which prevents evaporation) is thin or missing. Without a healthy oil layer, no amount of artificial tears will stay on the eye long enough to make a difference. You end up putting drops in every 30 minutes and still feeling the burn by late afternoon.
The oil layer comes from the meibomian glands in your eyelids. Every time you blink, these glands release a thin layer of oil that caps the tear film and prevents evaporation. When the glands are clogged, inflamed, or atrophied — a condition called meibomian gland dysfunction (MGD) — tears evaporate quickly and chronic dry eye follows. The fix is to treat the glands, not just flood the eye with saline. At PersonalEyes, Dr. Patel uses meibography (infrared imaging of the meibomian glands) to actually see the condition of your glands, tear film breakup time to measure how fast your tears evaporate, and a full ocular surface evaluation to identify every contributing factor.
For Lewisville patients specifically, the profile we see most often is: 30 to 50 years old, long commute to Dallas or Irving, office job with 8+ hours of screen work, worsening eye fatigue by mid-afternoon, relief when you get home and rest, and years of increasingly desperate use of artificial tears. Sound familiar? The good news: this is a very treatable pattern once we identify which components are driving it.
Stop guessing. A 45-minute dry eye evaluation will tell you exactly what is causing your symptoms and what treatment will actually work. You can't fix a problem you haven't measured.
What We Look For
Dry eye is almost always multi-factor. A real evaluation identifies every driver — then treats each one.
The oil-producing glands in your eyelids become clogged or stop working. The most common cause of chronic dry eye — responsible for about 86 percent of cases.
Office workers, commuters, and screen users blink up to 60 percent less when focused on a screen, allowing the tear film to evaporate between blinks.
Car AC, office HVAC, and Texas summers strip humidity from the air and accelerate tear evaporation. Lewisville commuters get this exposure in cars and offices both ways.
Sjögren's syndrome, rheumatoid arthritis, thyroid disease, and rosacea all contribute to dry eye. We screen for these and coordinate with your primary care provider when needed.
Antihistamines, antidepressants, blood pressure medications, and hormone therapies can all reduce tear production. We review your full medication list as part of the evaluation.
Poorly fit or older-generation lens materials can contribute to chronic dry eye. We evaluate both the lens and the tear film during the workup.
Book a dedicated dry eye evaluation. We will identify exactly what is causing your symptoms and build a treatment plan that actually works.

Frequently Asked Questions
Artificial tears treat the symptom, not the cause. About 86 percent of dry eye is actually caused by meibomian gland dysfunction (MGD) — the oil-producing glands in your eyelids are clogged or underperforming, so your tears evaporate too fast no matter how many drops you put in. The fix is treating the glands, not endlessly replacing the tear film. At PersonalEyes, Dr. Patel uses meibography imaging to actually see the condition of your glands, then builds a treatment plan that addresses whichever combination of problems is driving your dry eye. Many Lewisville patients who have been 'doing drops for years' see real improvement within a few weeks of the right treatment.
Modern work life is essentially a dry eye factory. Long commutes with car AC blowing directly at the face, 8 or more hours of computer work in HVAC-regulated offices (where humidity is typically 30 to 40 percent), reduced blinking during screen use (you blink about 60 percent less when focused on a screen), and evening screen time for entertainment — all compound into chronic tear film instability. Lewisville residents who commute to Dallas, Irving, or Fort Worth are especially vulnerable because they get this exposure twice a day. The solution is not just 'blink more' — it is addressing the underlying gland health and tear chemistry with real treatment.
A real dry eye workup is much more than asking 'do your eyes feel dry?' We use the Topcon Myah for meibography (infrared imaging of the meibomian glands to see gland structure and dropout), tear film breakup time measurement, tear osmolarity testing, lid margin evaluation, corneal staining, and a detailed symptom questionnaire. We also look for underlying causes — autoimmune conditions like Sjögren's syndrome, medications that cause dry eye as a side effect, rosacea or blepharitis affecting the lids, and contact lens wear. Dr. Patel then creates a targeted treatment plan based on the actual findings, not a generic protocol.
Yes — and it is an underrecognized occupational issue. Teachers talk for hours at a time, which reduces blink rate and dries the ocular surface. They use smart boards, laptops, and projectors throughout the day, further reducing blinks. Many classrooms have aggressive HVAC systems. And teachers often power through mild dry eye symptoms because they can't stop teaching to take care of their eyes. Multiple Lewisville ISD teachers are in our dry eye program and many report significant improvement once they get past the 'just use drops' phase and into real treatment.
It depends on the cause and severity. Simple meibomian gland expression combined with warm compresses and omega-3 supplementation often shows improvement within 2 to 4 weeks. More severe cases involving significant gland dropout or inflammation may require 8 to 12 weeks of consistent treatment to see meaningful relief. Dr. Patel sets realistic expectations at the first visit and follows up to adjust the plan if it is not working fast enough. Dry eye is a chronic condition in most cases — it can almost always be managed, but it usually requires ongoing attention rather than a one-time fix.
Yes. Contact lens-related dry eye is one of the most common reasons Lewisville patients come to us. Many lens wearers assume discomfort, fluctuating vision, and end-of-day burning are 'just part of wearing contacts' — they are not. We evaluate your tear film, your current lens material and fit, and your meibomian gland health, then adjust whatever is needed. Sometimes the fix is a different lens material or a daily disposable; sometimes it is dry eye treatment; often it is both. Many patients who had been told they could not wear contacts comfortably end up happy in their lenses after real treatment.
