Considering that 80% of our learning is done through our vision, it’s about time we paused to appreciate the beautiful wonder that is the human eye.

Made up of 200 MILLION working parts, the eye is the second most complex organ in our body after the brain. This prototype of the camera functions in similar but much more complicated ways than its manmade copy, be it a Canon DSLR or the one installed in your fancy iPhone.

Your retina actually perceives the world as upside-down images and your brain synchronizes immediately to flip the images so that you perceive things correctly. If you try on a pair of prism glasses, you’ll get an idea of how the world actually looks like to your eye.

All babies are born with blue eyes. The colour pigmentation changes within days and weeks of birth. Though your ears and nose grow as you become older, the size of your eye remains almost the same as it was at birth.

The cornea of the eye, the transparent layer covering the front, is the only tissue in the human body that does not have any blood vessels.

Ever wondered why retina scans are such an integral part of security checks now? It’s because compared to a fingerprint, which has 40 unique characteristics exclusive to you, the iris of your eye has 256.

The muscle that controls blinking is the fastest in the human body. On average, we blink once every 5 seconds; that means an astounding 6.5 million times in a year.

It may have something to do with ‘seen it all, done it all’ psychological cynicism, but it’s a medical fact that the older we get, the less tears we shed. According to research, adolescence is the time our tear production is at its peak. Small wonder.

A final, eye-opening reminder — don’t take the blessing of your eyesight for granted. Across the world, there are 39 million people who are blind, and six times that many are suffering from some kind of visual impairment.
