The iris eye meaning refers to the muscular pigmented curtain closest to the front eye, between the lens and the cornea. Iris can be located in the human body and nearest to the lens, which is situated behind the cornea. The Iris is bathed behind and front by a liquid called aqueous humour. The Iris in the eyes has two layers of smooth muscles, such as contractions and dilation. With the muscles' help, pupils control the density of light that reaches one's retinas and sensory issues. The percentage of pigment controls the eye colour of any creature.
The ring-shaped membrane in the eyes is called the Iris that surrounds the opening of the pupils. Pupils are the openings or the black holes that are built in the centre of an Iris. Pupils are circles with tissues of the Iris. The relationship of pupils and the Iris are very dependable among each other. Sphincter Muscle in the Iris, which is a circular muscle that restricts the pupil in bright lights. Strength in the Iris is the dilator muscle that controls the opening and closing of the eye muscles. Iris is the muscle that controls the pupils' activities to make them change in more extensive and minor as per the situation.
Let us take a look at the structure of the pupil and iris of eye. Iris is an annular and thin structure in the human body responsible for managing the size and the diameter of pupils in the Human Eye. Human Iris also controls the percentage of light that reaches the retina and tissues of the human body. The colour of human Iris also depends on the genetics of the person.
Appearances of blue rings around the Iris occurs due to the storage of cholesterol in the human retina. The storage items in the retina are mostly yellowish or white, though it appears as blue. However, this is not at all a risk factor for the human eyes. It has been said by the researchers that from 20%-35% of the people tend to have an Iris blue look.
As per the scientific views, researchers have noticed that there are two types of eye colours that can be seen in Irises. The main reason behind these different colours of irises is because people have central heterochromia. Heterochromia can be of various types such as complete heterochromia, central heterochromia, Sectoral heterochromia and others. It is possible that people with Heterochromia can have two different colours of irises. One is black, and the other one is blue. Few reasons can cause heterochromia in the human body such as eye surgery, diabetes, eye injury, swelling of the Eye, and others can cause the disease that reflects by having different colours iris in the human body.
With the pupil's help, the term Iris Eye is responsible for controlling the lightning that reaches the human retina. This activity of the Iris Eye is essential as too little or too much light can cause harm to the eyes. With the help of the big Iris Eyes, the muscles of the eyes widen when the percentage of light is low, and they are narrowed whenever there is too much lighting. The Iris is structured with smooth muscle fibres and connective tissues. The possibilities of changing someone’s iris are meagre. Mostly the change in the eye colour happened due to the extreme effect of lighting and nearby colours.
There are many ways that the use of Iris in eyes has proven beneficial to the people. Iris protects the retinas from being hampered by the high radiation of lights and vice versa. Iris has muscles that are attached to it that helps the eyes to change their shape. Iris worked together with the pupils and helped people by making them see things.
It has been seen in researches that irises can be divided into six types such as blue, ombre, grey, brown, green, red or hazel. There are few types of irises, such as iris eye, flowers type iris eye, the shakers types iris eye and others. The Jewel types of iris eyes include irises that have brown dots or flecks in them.

In many cases, heterochromia can be genetic, and it can happen from a few diseases such as diabetes. Eye surgery and swelling in the eye can also cause heterochromia.
