Top Seven Reasons Your Eyes are Incredible
Our eyes are amazing examples of biological engineering. They provide a high-resolution view of the world and can adjust focus across a range of distances. We rely upon them the entire day, and expect clear vision at a moment’s notice when waking up for a midnight snack. Our eyes deserve all the recognition we can give them. So let’s take a minute to highlight seven incredible facts about the human eye.
- Your eyes are recognizable just six weeks after conception. This is even before your toes start to form – not that it’s a competition.
- The eyes can resolve objects down to about .04 mm wide, about the thickness of a fine strand of human hair. When it comes to eyes, though, size doesn’t matter. They can detect anything - even groups of particles - if they emit enough light.
- Scientists estimate that humans can perceive up to 1 million shades of color, though we’re limited to the ROYGBIV tones that fall within the visible spectrum.
- The most distant object visible to the naked eye is the Andromeda Galaxy, located 2.6 million light years away. That’s over 15,000,000,000,000,000,000 miles!
- Our eyes are extremely good at tracking objects. In fact, from the moment something moves, it takes only 200 milliseconds for your eyes to set their sights on it.
- The patterns in your iris are one-of-a-kind, and are likely determined by eye movements in the womb. Iris-recognition technology is one form of biometric identification. So, Minority Report-style iris tracking isn’t all that far-fetched, after all.
- Geneticists believe that blue eyes can be traced back to a single person who lived less than 10,000 years ago. That means people with blue eyes share a common ancestor, making the iris an incredible record of humanity’s genetic past.
- As amazing as they are, your eyes don’t come with a user manual. That’s why it’s important to schedule regular check-ups with an optometrist or ophthalmologist. Luckily, Eyeconic can help you find an eye doctor.
