How does dry eye affect our eyesight?
Our eyes need tears to stay healthy and comfortable. Each time we blink, a protective coating of tears is spread like a film on the surface of our eyes.
Tear films has 4 important purposes:
- Protects and lubricates the eyes
- Reduces chances of eye infection
- Washes away foreign particles
- Smoothens the surface of our eyes to maintain clear vision
If we don’t blink enough or fail to produce a stable and good quality tear film, dry spots will develop on the surface of our eyes and cause discomfort and blurry vision. Airborne harmful particles or bacteria can easily stick onto our eye and potentially lead to irritation or inflammation.
