Dry Eye
What is dry eye?
Some people do not produce enough tears to keep the eye
healthy and comfortable. This is known as dry eye.
Tears are produced by two different methods. One method
produces tears at a slow, steady rate and is responsible
for normal eye lubrication. The other method produces large
quantities of tears in response to eye irritation or emotions.
Tears that lubricate are constantly produced by a healthy
eye. Excessive tears occur when the eye is irritated by
a foreign body, dryness or when a person cries.
