5 Critical Eye Functions that Make the Difference, from Park Ophthalmology

As 2018 approaches, Triangle residents are enjoying the holiday season, viewing festive decorations and recording their memories on smartphones and tablets. The desire to keep a visual record of the season demonstrates the large role vision plays in human life. Vision is the main sense that tells people about the world. Dr. Beth R. Friedland has devoted her career with Park Ophthalmology to give patients the best vision possible so they can enjoy the colorful, wonderful world around them. It’s easy to take vision for granted, but it plays a major role in everything from eating to falling in love.

Five important jobs done by the human eye as we head to 2018:

  • Experience and memory: Vision accounts for about 80 percent of humans’ input about the world. Visuals such as photos and videos provide the main archives of life events and easily bring those memories to mind.
  • Location: A dark room offers many hazards, especially in unfamiliar surroundings. Humans use their visual sense to navigate the world. Those with night blindness know too well how difficult it can be to drive in low light conditions.
  • Eating: Humans can only distinguish five flavors of food, so they use their eyes to help them decide what to eat. Vision is used to determine whether something looks fresh and wholesome or old and moldy. Brightly colored vegetables and fruits draw the eye, enticing humans to make good food choices.
  • Romance: Scientists have discovered that the eyes’ pupils will involuntarily dilate when a man or woman sees someone attractive. Several studies have found that men are more attracted to women with larger pupils. Maybe “love at first sight” is a real phenomenon.
  • Balance: Most people know the inner ear plays a primary role in maintaining balance, but vision contributes important information too. Vision helps people know where they are in their environment and what obstacles are in their way. Researchers report that poor vision contributes to balance problems and a risk of falling.
