The colored part of your eye is called the “iris”. This part of your eye is pigmented depending on your genetics, which will determine what eye color you have. Many babies have blue eyes when they are born and for most of their first year of life. However, that might not be the eye color that they will always have, as pigmentation in the eye can change over time.

Your retina is one of the most important parts of your eye and one that is vital for clear vision. The seeing process is very complex and involves many parts of the eyes working together correctly. The retina is key for interpreting light and telling your brain what you are seeing.

New research has led scientists to believe that people may not see all the same colors when they look at the same things. It comes down to color perception. Although most of us would agree that red is the color of tomatoes, strawberries and stop signs, scientists now think that one person's red could be another person's blue.

Color blindness affects more than 3 million Americans each year. Men are more prone to this condition than women. Even though millions of Americans are affected by it, not many know what it actually is. This condition is also known as “specific color vision deficiency (CVD)”, because there are different types of blindness when it comes to seeing colors.
