Eyes have complex anatomy and amazing physiological functioning. Although much is known about the function of eyes, yet various myths are prevalent among the people. For better care of the eyes, these myths should be debunked.
Our eye is one of the most fascinating sensory organs. The working of the eye is complex. Eyes are the perfect example of the integration of physical, chemical, and neuronal interaction. Because of this complexity, there were various unproven facts prevalent about the eyes. Some are myths as they are disapproved through scientific theories. The following are some of the common myths that are not backed up by any scientific evidence and even disapproved.
Myth Buster: During the eye examination, the pupil is dilated. This allows the doctor to see deep into the eyes during the examination. The pupil regulates the amount of light entering into the eyes. Before the ocular examination, the doctor administers eye drop to dilate the pupil which remains dilated for a few hours till its effect wears off. Once the examination is over, you should wear sunglasses as the increased entry of light in the eyes causes discomfort and strain to the eyes.
Myth Buster: Many people think that blinking is under their control.
But it is not so. Our eyes are controlled by various muscle and reflexes. This is the reason why we can see the danger coming from our side even when we are looking straight.
Myth Buster: The eyelids are an important part to protect the eyes and ensure tear spread. Blinking of eyes is an involuntary process and is a part of human natural reflex. Whenever the eyes get dry, the eyelids blink automatically.
Myth Buster: Many people think that the makeup used for eyes does not have an expiry date. It is not so. Makeup is chemicals and like other chemicals, they also deteriorate. Using the makeup beyond expiry date on the eyes may increase the risk of infections and allergic reaction.
Myth Buster: Sunglasses are used to prevent the damaging effect of solar UV radiation on eyes. People think that sunglasses protect the eyes from UV radiation only on bright sunny days. However, it is to be noted that even on a cloudy day, eyes are getting exposed to solar radiation. So next time when you go out on a cloudy day, do not forget to carry sunglasses.
Myth Buster: There is no change in the physiological functioning of eyes due to wearing glasses and contact lens. Thus, the vision does not deteriorate. However, the brain prefers a clearer vision that can be achieved through wearing glasses and contact lens.
Myth Buster: It is a common myth that looking into computers for a long time may deteriorate your vision. However, it is not true. Prolonged working on computers may lead to computer vision syndrome which may lead to dry eyes, which is manageable and does not cause any permanent change in your vision.
Myth Buster: People believe that eating more carrots may improve their vision. Carrots contain beta-carotene which is converted to vitamin A in the body. Vitamin A is important for vision. However, eating carrots will benefit only those patients who have a deficiency of vitamin A. People with sufficient Vitamin A level may not be benefitted from eating carrots.
