4 Fascinating Facts about the Human Eye from Park Ophthalmology

park-09-05-16-stockimages-id-100218537From the time most people across Raleigh and Durham get up in the morning, until they turn off the lights at night, their eyes are constantly taking in the world around them. Dr. Beth R. Friedland of Park Ophthalmology in the Triangle enjoys sharing helpful information about vision with her patients. Understanding how the eyes work can help patients understand how important sight is and how fragile it can be. In this informational post, we hope our readers, friends and patients learn some interesting facts about eyes and vision.

Park Ophthalmology offers four little known and interesting facts about the human eye and our vision:

  • Eyes work hard: Doing 100 sits ups feels like a good workout, but the muscles that control the eyes are the most active muscles in the human body. They are always “on.” Consider that even during sleep, humans have REM (rapid eye movement), during which the eyes move quickly behind closed lids. Some scientists speculate the movements may be connected to dreaming.
  • Eyes clean themselves: People blink about 12 times a minute. Each blink is only one-tenth of a second, but that tiny bit of time is critically important to eye health. A blink spreads a film of tear liquid to both clean and lubricate the eyes. Unfortunately, Dry Eye Disease affects eye health for many in the Triangle. Park Ophthalmology has a Dry Eye Clinic to accurately diagnose dry eye conditions.
  • Eye color may not match: Babies have a six in 1,000 chance of being born with eyes that are different colors; however the difference is usually slight and not noticeable. Called heterochromia, this trait also is seen in dogs, cats and horses. Celebrities with heterochromia include Jane Seymour, Dan Aykroyd, Max Scherzer and Demi Moore.
  • Eyes have natural guardians: Human eyes have multiple built-in protectors. Lids shield the eyes from flying particles and bright light. Eyebrows keep sweat from getting into the eyes; and the eyelashes help keep out dirt. Located in recessed eye sockets, the skull provides even more protection.

These interesting facts are just a few of the surprises about eyes.
