Your eyes are a crucial feature in your anatomy because it enables the sense of sight. Sight enables us to absorb much more stimuli that any of our other four senses and that is why it is utilized in almost every activity that we perform with the exception of sleeping. If you as an individual were asked to pick one of the five senses in your body that you would like to have for life, we are sure that it would be sight, seeing as it is a detrimental attribute that is used constantly in ones day to day life. The eye allows one to not only see but also interpret various colors, shapes and dimensions based on the light reflection capacity of the said object. Even though the eyes detect bright and dim lights it is unable to function in complete darkness due to the complete absence of light. The anatomy of the eye is therefore a complex and beautiful part of the human body that is worth getting to know for the betterment of your life.
The process in which the eye functions is a truly beautiful aspect of nature in its full form of technological brilliance. For example imagine that there is an inanimate object in front of you. In order for you to see this it is important that a certain amount of light enters your eye through the cornea. The cornea is the clear round dome at the front of the eye. The light then flows through the cornea and in to the pupil which is the circular portion at the center of the colored iris which is the colored part of the eyeball. Changes in the amount of light correlates with the size of the pupil. The darker it is the larger the pupil gets in order to retain more information and the lighter it is the more constricted the pupil becomes because it is unnecessary for the pupil to take in an excessive amount of light as it is already present in the surroundings. This process is referred to as the pupillary light response.
When light enters the cornea in the initial stages, they are converged and then bent further by the crystalline lens which is located immediately behind the pupil to a nodal point that is located behind the inverted surface of the lens. Here the image focuses in a reversed manner and our brains turn the image the ‘right side up’ for us. It is therefore safe to say that we don’t see with our eyes but with our brains though our eyes are the instrument that enables the visual process to take place. The anatomy of the eye is therefore a truly beautiful process and we hope that this is motivation for you to ensure the absolute safety of your eyes because it is indeed a vital function for your system.
