What is Your Most Valuable Tool?

What is Your Most Valuable Tool?

I have had a few jobs in my lifetime. It does not matter where you are in life or what you do for a living, one of the most important things is that you are able to see what you are doing. That’s right, your eye sight, might be the most valuable tool you have.

How much do you know about how we see this world in which we live? I am no expert at all, but at a certain age I have started feeling the effects of vision problems. While doing some research on this topic I found a few interesting facts.


  • We do not see through our eyes, but instead our Brain
  • Light enters the eye through the cornea, a clear domed shape surface that covers the eye , it refracts or bends the light
  • The Iris adjusts the size of the pupil which regulates the amount of light that enters the eye
  • The Lens is behind the pupil, it further focuses light onto the Retina
  • The Retina is a thin, delicate, photosensitive tissue that contains the special “photoreceptor” cells that convert light into electrical signals.
  • The eye is basically a very complex camera lens that sends electrical signals
  • These signals travel from the Retina to the Brain via the Optical nerve through about a million nerve fibers
  • Our eyes collect visual information and begin this complex process

This information and more is readily available on the National Eye Institute website.

Tips for healthier vision:

  • Schedule a comprehensive dilated eye exam
  • Wear proper eyewear with a UV-A and UV-B protection
  • Give your eyes a rest if you work on a computer for long periods of time ,the 20-20-20 rule is easy to remember Every 20 minutes , look away from your computer focus on something about 20 feet away from you, for about 20 seconds
  • For contact lens users , clean your hands and contacts properly
  • Eat a diet rich in fruits and vegetables, especially dark greens such as spinach, kale, or collard greens, and fish high in omega-3 fatty acids, such as salmon, tuna, and halibut
  • Maintain a healthy weight and BMI
  • And lastly no smoking, research has linked smoking to an increased risk of developing age-related macular degeneration, cataracts and optic nerve damage, all of which can lead to blindness

We all take our bodies for granted from one time or another . Going about our business and never thinking beyond the fact that this amazing body seems to run on auto pilot day in and day out. Being able to see your work is an ability that almost everyone takes for granted. Simply be thankful for your eyes and understanding of how they work for you in your everyday life.

What are the things you can enjoy without your sight? How are you seeing these days? When was your last eye doctor check up? Don’t delay to get this most valuable tool checked and calibrated for its best results.
