The Human Eye: Facts you may never have known!

The eye is a powerful organ for vision. It is capable of doing some remarkable things such as blinking within milliseconds, and heals with agility.

INFRARED SIGHT
Prior to now, it was generally believed that the eye can only view rays in the visible spectrum. But recently some researchers from Washington University in St. Louis discovered that the human eye is in fact capable of seeing infrared light-- but only under certain conditions. This is a big milestone that may alter the way we have traditional viewed the eye.

ACTIVE MUSCLES
The eye muscles are constantly contracting or relaxing when you are looking around or focusing on an object, near or distant, or even in some deep dreams. I also learnt that just in one hour of reading a book, the eyes makes up to 10,000 coordinating movements. The ability to repeat precise motions in the eye is also very strong. And just as you do sit ups for your abdominal muscles, you can do eye stretches to make your eye movements more fluid and to reduce tension in your eye muscles.

EYE LENS IS QUICKER THAN CAMERAS
The camera and it's components (including the lens) was built with the human eyes in mind. But the eye lens focus on object in split second whereas a camera lens tends to take a bit longer to focus. This allows you to look anywhere without feeling sick, or having blurred vision.

HEALING POWERS
Provided it's not a deep abrasion, the eye has very unique healing powers, with healing occuring in 48 hours after a corneal scratch.

BLINKING MOTION
On the average, a normal person blinks up to 15,000 times every day which is about 10 percent of our waking hours. The blinking action of the eye ensures that any form of tiny particle, dust or debris on the surface of the eyes, is cleared away. Blinking also keeps the eye surface wet to avoid corneal dryness, that may complicate the function of the eye.
