Comprehensive Dry Eye Care
Understanding Dry Eye
Dry eye disease develops when your eyes do not produce enough tears or when the tear film does not stay balanced. Learning how the tear system works helps explain why symptoms appear and how treatment brings relief.
The tear film is a thin, three-layer coating that covers the front of the eye. It keeps the surface smooth, protects against irritants, and supports clear vision.
Produced by the meibomian glands, this layer slows evaporation and seals in moisture.
Formed in the lacrimal glands, the watery layer rinses away dust, allergens, and debris while delivering nutrients to the cornea.
Mucus from goblet cells helps the watery layer spread evenly and stick to the eye’s surface.
When any tear layer fails, the surface of the eye can become inflamed or damaged. This condition, called ocular surface disease, may lead to discomfort, blurry vision, and poor surgical outcomes if not treated.
Recognizing Dry Eye Symptoms
Dry eye can present in many ways. Knowing the signs helps you seek care before irritation escalates.
A constant feeling of dryness suggests the tear film is not providing enough hydration.
An unstable or thin oily layer lets tears evaporate quickly, leaving the surface exposed and irritated.
Inflamed blood vessels make the eyes look red when the tear film fails to protect delicate tissues.
Itching can stem from allergies, blocked oil glands, or inadequate tear production. Identifying the cause guides the right therapy.
- Allergies to pollen, dust, or pets
- Blepharitis or meibomian gland dysfunction
- Environmental irritants like smoke or wind
- Extended screen time that reduces blinking
A smooth tear film forms the first optical surface of the eye. Breaks in the film scatter light and blur vision until the next blink restores clarity.
Dry spots on the cornea scatter light, causing glare, halos, and discomfort in bright settings.
The eyes may flood with watery tears to compensate for dryness, yet these tears lack the oils needed for lasting moisture.
An imbalanced tear film can leave stringy discharge or morning crusting, often worsened by blepharitis.
Surgery and Dry Eye
A healthy tear film is vital before, during, and after eye surgery. Proper management improves comfort, healing, and visual results.
We evaluate tear quality, gland function, and inflammation to ensure accurate measurements and prepare the eyes for surgery.
- Comprehensive dry eye testing
- Treatments such as LipiFlow, intense pulsed light, or prescription drops
- Control of ocular surface inflammation
Surgical techniques and moisture shields protect the ocular surface and reduce trauma that can worsen dryness.
After surgery, nerves need time to recover, and tear production may dip. Ongoing care keeps the surface lubricated and supports clear vision.
- Preservative-free artificial tears and gels
- Punctal plugs or scleral lenses when needed
- Regular follow-up to adjust treatment
Who We Help
Dry eye affects people in different ways. Our specialists tailor care to each patient’s needs and lifestyle.
For persistent dryness that disrupts reading, computer work, or outdoor activities, we focus on restoring balance and comfort.
Blocked or inflamed glands speed tear evaporation. Targeted therapies clear blockages, reduce inflammation, and stabilize tears.
Rosacea around the eyes can intensify dryness. Treatments such as intense pulsed light reduce skin inflammation and improve tear quality.
Autoimmune disease, hormonal changes, thyroid disorders, diabetes, and other systemic issues can worsen dry eye. Coordinated care addresses both eye and overall health.
- Sjögren’s syndrome and other autoimmune diseases
- Hormonal shifts during pregnancy or menopause
- Thyroid eye changes
- Diabetes-related tear film changes
- Medications that lower tear production
Lenses can disrupt tear distribution and absorb moisture. Switching to lens materials designed for dry eye or adjusting wear time often brings relief.
Advanced Dry Eye Treatments
Our clinic combines proven therapies with modern technology to treat the root causes of dry eye and provide lasting comfort.
iLux gently warms and expresses the meibomian glands, melting thick oils and restoring a stable lipid layer.
Tiny plugs placed in the tear ducts slow drainage so natural tears stay on the eye longer, reducing dryness and irritation.
We build personalized plans that address every layer of the tear film and encourage healthy habits.
- Improve lipid layer function
- Enhance natural tear production
- Reduce surface inflammation
- Protect the cornea from damage
- Teach lifestyle changes that support eye comfort
Frequently Asked Questions
Below are answers to common questions our patients ask about dry eye care.
Severe or untreated dry eye can harm the cornea and blur vision, but early diagnosis and proper treatment prevent long-term damage.
Use preservative-free tears as directed by your eye doctor. Some patients need drops several times a day, while others may need them only during specific activities.
Symptoms often improve with treatment, but underlying causes like gland dysfunction or systemic disease usually need ongoing management.
Yes. Staring at screens reduces blink rate, which lets the tear film break up faster. Regular breaks and conscious blinking help keep eyes moist.

Dr. Simon and staff were helpful and professional. Tiny eye tubes were placed to treat my dry eye condition—after a short adjustment, it’s working, and I haven’t needed eye drops. Thanks, Dr. Simon!
Lissa Moy
My experience with Dr Ahmed Nasrullah treating cataracts in both eyes went very smoothly The pre and post operation was well done the two operations could not have gone better.

I had a wonderful experience getting LASIK! By the next morning, I was seeing 20/20. The doctor was kind and efficient, and the office made everything stress-free. Very happy with the results.

I classify as very elderly. I have been a patient at Dulles eye for approximately 8 years I have been completely satisfied, especially with Dr Dar. I recommend the entire practice with no reservation.
