Dolphins sleep with one eye open. Snakes have two sets of eyes- one set used to see and the other to detect heat and movement. A dragonfly has 30,000 lenses in its eyes , assisting them with motion detection and making them very difficult for predators to kill. Some people have a fear of eyes: its called ommatophobia .

9. Eyes are the second most complex organ after brain. Our eyes are made up of over 2 million working parts. While a fingerprints has 40 unique characteristics , an iris has 256 . This is why retina scans are increasingly being used for security purposes. When working at a computer , we should follow the 20-20-20 rule – look at something twenty feet away from our computer every twenty minutes for twenty seconds.
