Image is from Think About Your Eyes
Although we at times take it for granted, seeing is undoubtedly one of the most important functions of the human body. The role played by your eyes cannot be underestimated at all since the eyes are helpful in almost all the aspects of your life. In many cases, the eyes have been referred to as the camera of the body. They have been likened to a camera for reasons such as:
- Both devices perceive images
- After gathering light, they both focus and transmit it through the lens
- Both help in creation of images of the surrounding environment
Taking care of your eyes begins with knowing how important they are and the specific functions they have. Below is an outline of the importance of your eyes.
Color and Image Perception
As a sense organ, the eyes help in distinguishing different images and colors. The eye’s retina is a part that contains millions of light-sensing neurons called cones and rods. They are responsible for the perception of color details after which they convert the light into electrical impulses. The converted impulses are then sent to the brain for interpretation. The eyes give the vision needed for activities such as driving, reading and making decisions when you are required to choose from various things.
Production of Tears
Many people think that tears are only useful when they need to express their emotions like when they are happy or sad. Tears, however, have many other functions such as nourishment of the eyes, vision maintenance, washing away debris and lubrication. Your eyes have a tear system that involves three parts: the glands that form tears, the openings through which tears flow from the eyes and ducts that drain tears into the nose. The eyes are therefore very essential to the production of tears.
Keeping us safe
Sight is essential for safety and self-preservation. Life is full of dangerous obstacles, and the eyes help us avoid them. It would be very dangerous to walk around or do different things without the eyes. They are therefore very instrumental in ensuring your safety and provide awareness of any danger within our environment.
Connecting with the surrounding
You would never get to connect with the many things that happen in the immediate surroundings. Even if you hear about them, it would not be as good as it would be if you witnessed them occurring. Your eyes give you the ability to perceive movements as well as assess the intentions for different forms of motion. Eyes help in bringing out the beauty of the world around us. Most of our preferences depend on what we see. We like the things which are more appealing to our eyes.
Other than perceiving images, your eyes help in sensing. There are times when one of your senses could be missing. When you have a cold, for instance, you tend to lose the sense of taste and smell. It, therefore, becomes very different to detect rotten foodstuffs which upon consuming would cause digestion problems. In such a scenario, the eyes take over this work. The only way to distinguish what is edible from the inedible would be by carefully scrutinizing the foodstuffs to identify traces of molds or any other indication of food spoilage.
Due to this, it is important to take care of your eyes. The best way of looking after your eyes is by visiting an optician regularly to get checked. Through this it will be easy to detect any issues and correct them before it is too late, maintaining your quality of life.
