Those Tiny Teardrops: Why Are They So Important?

When you hear the word “tears,” what comes to mind? A sad or joyful time in your life? A song or movie that brought tears to your eyes (a tear-jerker)? But the fact is, our tears play an important role in our vision and the health of our eyes. Our ophthalmologist at Mountain View Eye Center, who specializes in protecting the health of these complex organs, wants you to know more about the precious fluid contained in our tears.

Where do our tears come from? Our tears are produced mostly by glands located above each eye. Glands found within the eyelids secrete oil that helps prevent tears from evaporating.

What do our tears contain? Water is the primary component of tears, but also contained within these drops are:

• Electrolytes like sodium, potassium, and chloride, which give tears that salty taste.
• Proteins Including an enzyme that fights bacterial infections, and antibodies that help protect the eye.
• Oils that help prevent tear evaporation and keep the surface of the eye smooth.
• Mucus that helps spread tears evenly across the surface of the eye,

Why are our tears important? 

• They lubricate the surface of the eye, which prevents dryness and irritation.
• They contain enzymes that fight infection and wash away dust, debris, and irritants.
• They carry essential nutrients to the cornea, the clear front surface of the eye.
• They create a smooth surface for light to pass through, supporting clear vision.

What happens if we don’t produce enough tears?

Symptoms include dryness, irritation, a burning or gritty sensation, redness, blurred vision, difficulty focusing, and sensitivity to light. Corneal abrasions (scratches on the surface of the eye) can also occur.
