5 Iris Facts

The iris is one of the most interesting parts of the human eye. In fact, many people ask their eye doctors in Miami about this portion of their eye because they want to know about the unique color they were born with. The iris is responsible for more than just the way a person appears, though, it does have a practical function that allows people to see as easily as they do. When patients ask their Miami eye doctor about this portion of their eye, they are likely going to be given the known facts about it that most people are going to find interesting and may not know.

What You May Not Know About the Iris

Your eye doctor may tell you some interesting things about your iris if you ask them how and why it functions on your next visit. There are also some interesting studies about the iris colors and how they are related to personality traits that you may find out about as well.

● The iris is the portion of the eye that’s responsible for restricting how much light gets passed into the retina. When it’s bright outside, the iris contracts and allows less light in the eye, and vice versa at night.

● The color of an eye is determined by how much melanin, or pigment, is present in the eye. When lots of melanin is present, the eye color will be darker. Less, and the eye will be lighter.

● Heterochromia is an eye condition that’s distinguished by having two different colors, one in each eye.

● Iridology is the study of the iris and how changes in its appearance over time are linked to health issues.

● There are actual procedures people can have to change the color of their eye. However, this is most commonly done for functional purposes, not just for looks. People with extremely light eyes often have them surgically changed to a darker color so they aren’t as sensitive to light.

Know Your Iris

The iris is probably the most interesting part of the eye because it’s what is first seen when people look at each other. The colored portion of the eye is most noticeable and it’s very distinct on some. People often wonder if wearing eyeglasses in Miami Beach is going to affect the way their iris functions, but this is not usually the case. The amount of light that passes into the eye is the same, regardless of whether someone is wearing refractive lenses or not. The next time you look in the mirror, take a moment to appreciate the color and function of your iris.
