What are the common symptoms of dry eye?Everyone experiences dry eye differently because there are so many potential underlying causes.
Dry Eye Symptoms

​
What causes dry eye?There are many potential causes of dry eye.
In some cases, the cause is obvious, such as environmental irritants or short-term inflammation.
Some of the other causes of chronic dry eye problems include:
  • Disease of the meibomian glands
  • Blepharitis
  • Allergies
  • Defects that affect the eyelid or shape of the eye
  • Certain medications
  • Abnormal eye pressure
  • Deficiency of aqueous fluids
Because the underlying causes vary, treatment methods after diagnosis will also vary according to the patient. It is also not uncommon for there to be more than one cause for dry eye.
How is dry eye diagnosed and treated?Through imaging of the meibomian glands, measuring osmolarity of the tear film, and screening for certain conditions, we are able to diagnose and provide treatment for the condition.
Some of the typical treatments include:
  • Prescription eye drops to combat inflammation
  • Treating oil glands
  • Blinking exercises or proper eyelid hygiene
If an infection is causing the issue, low-dose antibiotics may also be prescribed.
Dry eyes are not only uncomfortable — they can also be bad for the health of your eyes.  Text us at 7816762020 at Lexington Eye Care to make an appointment with Dr Zhang.
