5 Surprising Facts About Your Eyes

Posted by Eye Specialists of Louisiana on Mon, Jul 15, 2019 @ 04:50 PM

5 surprising factsThey come in many shapes, sizes, and colors and have been deemed the “windows to the soul”.  They are among the first facial features that others notice, and they can determine how attractive or even trustworthy you seem.  Undoubtedly, the eyes play a vital role in our day-to-day lives and interactions, but they are responsible for so much more than simply seeing all that surrounds us.  The eyes are constantly at work and sending signals to the brain that can instantly impact the rest of the body.  If your eyes detect a threat, for instance, it can trigger an entire chain of events that produces your natural fight or flight process, and this is just one example.  There are so many different functions of the eyes of which most are unaware.  So, let’s take a moment to appreciate them and explore a few of the most surprising facts about our amazing eyes!

The Seeing Process Involves About Half of the Brain

The area of the human brain responsible for all visual information is known as the visual cortex.  It is the largest system within the brain, with each hemisphere containing a visual cortex.  The visual cortex located in the right hemisphere receives information from the left visual field, and the one located in the left hemisphere receives information from the right visual field. 

Eye Muscles are Among the Strongest in the Body

The external muscles of the eye are among the strongest in the human body for what they have to do.  When considering their size, these muscles are often said to be 100 times stronger than is necessary.  They make constant coordinated movements to support and adjust the eye.  Even when we sleep, our eye muscles continue to work through rapid eye movement.

Every Eye has a Blind Spot

There is a point, where the optic nerve meets the retina, where the human eye contains no photoreceptors.  This spot has no response to light stimulation and results in a blind spot.  You don’t notice this spot, because your eyes work together to fill it in.

Eyes are Always Ready to Function at 100% Capacity

The eye is the only part of the human body that is constantly on its “A game.”  The eyelid and external muscles of the eye need rest, and the lubrication for your eyes needs to be replenished.  However, your eyes themselves are able to function at 100% any time of the day or night.

Your Eyes Have Over 2 Million Working Parts

After the brain, eyes are the most complex organs in the human body.  It takes over 2 million working parts for them to function properly.  These parts enable the eyes to do some incredible things, such as process 36,000 pieces of information every hour and focus on about 50 different things each second.

Keeping Your Eyes Healthy

Despite their incredible resilience and many amazing feats, the eyes require regular care to ensure that their job may be done well.  Regular eye exams are key to keeping vision and the eyes themselves healthy and strong.  In Baton Rouge, Eye Specialists of Louisiana offers a wide range of ophthalmologic services at our new, state-of-the-art office.  To learn more about our services or to request an appointment with one of our physicians, click the button below.
