What is Dry Eye ?
Millions of people around the world suffer from dry eyes. Many of those who experience the symptoms of dry eyes don’t realize the cause.

b. Low quality of tears.
What are the Symptoms of Dry Eye?

- persistent dryness, a sensation of having something like a grain of sand stuck in your eye,
- a feeling of pressure behind the eye,
- eye redness,
- sensitivity to light,
- blurred vision at the end of the day
Dry, windy, or dusty environments usually exacerbate these symptoms. Dry eye causes discomfort and leads to irritated eyes.
Visit your eye care provider if you experience any of the above symptoms.
Contact Lenses & Dry Eyes
Long-term use of contact lenses causes dry eyes because they decrease the sensitivity of the corneal nerves within the eye. This causes less tears to be produced. Attention: This effect is usually temporary.
Selecting the right contact lenses is crucial :
