David Bowie's eyes
Man of different personalities and probably the most amazing artist ever, David Bowie's most unique traits were his eyes. But contrary to the popular belief, he was not born like that nor he ever had different color eyes. At first glance, and probably what many people think, his eyes had different colors but after a better look we would realize that his pupils were just of different sizes, and that is a condition not so uncommon called “Anisocoria” (having different color eyes is called “Heterochromia”).
The fun fact is how David got this condition. It was 1962 and the then known as David Jones was a 15 years old teenager in love with the same girl as his friend George Underwood. Both friends got into a fight and at some point George hit David's eye, damaging it forever and thus marking one of the most characteristic features of rock history. If you wonder about the relationship between the two friends, it remained intact until the day of David's death in January 2016. Proof of this is that George years after the famous fight would design the album covers “Hunky Dory” (1971) and “The rise and fall of Ziggy Stardust and the Spiders from Mars” (1972).
