Our eyes are not only the windows of the soul but they are also the windows to the world around us in terms of helping us to perceive information in our environment and in our surroundings. Here are some interesting facts about the human eye that you will find intriguing. Blinking cleanses the surface of the eyes by removing debris from our eyes and it accomplishes this purpose by spraying tears all over our eye's surface. These tears serve various functions related to the protection of our vision health. They stimulate the production of natural tears and moisture in the eyes that have a lubricating effect on the eyes. These tears also have antibacterial properties and protect the eyes from eye infections, germs and viruses.
Here are some additional interesting facts about the eyes. Dogs are the only animals with the ability to communicate non-verbally with humans via the process of certain visual cues with other people.The pupil in your eyes expends as much as 45% when you are looking at someone you love. With regard to eye anatomy the second layer of the eye is called the choroid. It consist of the cornea which is the front surface of the eye through which light reflected from objects is let in. The Choroid also consists of the iris which is a layer of colored tissue. The small dark circle in the center of the eye is called the pupil. Therefore, here is some information relating to the function of the pupil in eye anatomy:
The pupil is surrounded by 2 sets of muscle fibers that are inside of the colored part of the eyes called the iris. Whenever the pupil is exposed to light it contracts and if there is little light the pupil dilates in order to allow more light into the eyes. The biological action associated with the constriction of the pupil is controlled by an inner layer of ring like muscle fibers that surround the iris. Additionally, there is a second layer of spoke like muscle fibers located on the outer part of the iris. Therefore, the main function of the pupil in eye anatomy is the regulation of light that enters the eyes.
The pupil is one of the parts of the eye that is located in the middle layer of the eye
which is called the choroid. It is the small dark circle located in the center of the eyes. A person's pupil becomes smaller in size when an individual is exposed to bright light and the pupil becomes larger or expands when there is little light. Therefore, the primary function of the pupil is to control the amount of light that is allowed into the eyes.
