“In the blink of an eye” means lightening quick! An interesting fact, humans blink from 15 to 20 times per minute, and a single blink lasts from one-tenth to four-tenths of a second. Those short moments are what keep eyes healthy and clean. When something goes wrong with tear production, the results can be dry, irritated eyes and blurry vision. Many Triangle residents have found help through Park Ophthalmology’s Dry Eye Clinic. Ophthalmologist Dr. Beth R. Friedland developed the clinic to help Triangle area patients who don’t produce enough natural tears.
These four interesting facts from Park Ophthalmology help patients understand the links between tears, blinking and their vision:
- Types of tears: Humans actually produce three different kind of tears: basal, emotional and reflex. A basal tear is the liquid that keeps eyes lubricated and clean. The cornea is flushed with fluid each time a person blinks, washing away bacteria and creating a smooth surface on the cornea. That smooth surface provides clearer vision and the lubricating quality of the tear prevents friction between the eyelid and cornea.
- Tear composition: Tears are composed of water, fats, sugars and proteins, but tears produced for lubrication and cleansing are different from those produced for emotional crying. In fact, emotional tears contain stress hormones that are released through crying, allowing the person to feel calmer afterward.
- Onions and tears: Cutting an onion often causes people to produce reflex tears. This is because the onion vapor is irritating and the body is attempting to remove the irritant. Tear gas, pepper spray, dust and allergens can have the same affect.
- Help for dry eyes: Anyone suffering from dry eyes knows the irritation and soreness the condition creates. Over-the-counter artificial tears may help short term and wearing glasses or sunglasses could help reduce symptoms. However, Beth R. Friedland M.D. can provide a longer-term solution.
