Eye colour is a manifestation of the pigment that is present in the iris. Brown eyes are rich in melanin deposits, and blue eyes indicate a lack of melanin. The melanocytes of the iris rest in a richly innervated psuedosyncytium, which is necessary to maintain eye colour.

The instance of a person having two differently colored eyes is pretty uncommon, just 11 out of every 1,000 Americans. This uncanny trait is caused by several factors, and can actually develop over time.

The important part of a human eye

The average blink lasts for about 1/10th of a second.While it takes some time for most parts of your body to warm up to their full potential, your eyes are on their “A game” 24/7.Eyes heal quickly. With proper care, it only takes about 48 hours for the eye to repair a corneal scratch.Seeing is such a big part of everyday life that it requires about half of the brain to get involved.Newborns don’t produce tears. They make crying sounds, but the tears don’t start flowing until they are about 4-13 weeks old.Around the world, about 39 million people are blind and roughly 6 times that many have some kind of vision impairment.Doctors have yet to find a way to transplant an eyeball. The optic nerve that connects the eye to the brain is too sensitive to reconstruct successfully.The cells in your eye come in different shapes. Rod-shaped cells allow you to see shapes, and cone-shaped cells allow you to see color.You blink about 12 times every minute.Your eyes are about 1 inch across and weigh about 0.25 ounce.Some people are born with two differently colored eyes. This condition is heterochromia.Even if no one in the past few generations of your family had blue or green eyes, these recessive traits can still appear in later generations.Each of your eyes has a small blind spot in the back of the retina where the optic nerve attaches. You don’t notice the hole in your vision because your eyes work together to fill in each other’s blind spot.Out of all the muscles in your body, the muscles that control your eyes are the most active.80% of vision problems worldwide are avoidable or even curable.

Photoreceptors contain chemicals that change when they are hit by light. This causes an electrical signal, which is then sent to the brain along the optic nerve. Different types of photoreceptor allow us to see an enormous range of light: from starlight to full sunshine, and all the colours of the rainbow.

The most common form of 'colour blindness' is red-green colour deficiency, which affects 7-10% of people. This is not actually blindness, but a difficulty in distinguishing shades between red and green. It is caused by a change to or loss of the light responsive chemical in certain photoreceptors. Total absence of colour vision, where everything is seen in shades of black and grey, is very rare, and is usually caused by brain damage.

When you look at an object, the light from it enters your eye through the pupil. The iris changes the size of the pupil, depending on how bright the light is. The lens focuses the light onto the back of the eye: the retina. The retina is a mass of light-sensitive neurons, called photoreceptors, which change light signals into electrical ones.
