London, UK (PRWEB UK) 15 August 2012
A leading contact lens retailer in the UK has published an infographic – 7 amazing facts about your eyes – in order to engage and educate people about what many consider to be the most essential organs in the body.
The infographic includes facts identified through recent scientific studies, as well as some more quirky facts.
It highlights recent scientific research which provides evidence that every person with blue eyes can be traced back to a common ancestor who lived thousands of years ago. It also provides more detail on how this came about, and what determines a person’s eye colour.
One area researched by Lenstore (http://www.lenstore.co.uk) for the creation of the infographic was eye colour. A fact which many people are unaware of is that a pigment called melanin determines the colour of a person’s eyes. Melanin is a dark brown colour, which controls eye, hair and skin colour. Because of this, the higher the concentration of melanin in the iris, the darker the eye colour. In contrast, lighter eyes have less melanin, allowing another substance called collagen to be more visible. Collagen is blue, which is why some people have blue eyes.
Until a few thousand years ago, nobody had blue eyes. Recent scientific research provided evidence that everyone with blue eyes can trace their lineage back to a single person who lived six to ten thousand years ago. This one person was born with a mutated gene, which resulted in a lower level of melanin being produced in the iris. Because this mutation didn’t put the individual at a disadvantage in terms of survival, the gene has been passed on over thousands of years.
Another fact highlighted by Lenstore’s infographic is that it is the brain which processes information and translates it into images which people can see. As a result of this, if someone was to wear a pair of glasses which flipped images upside-down, the brain would adapt to this over time so that the person saw things correctly again. However, taking off the glasses would again turn the world upside down and the brain would have to correct itself once more.
The infographic looks at promoting a range of additional interesting facts, and will no doubt be interesting to people with an interest in anatomy, biology or just a curiosity regarding random facts.
