Medical Video: How Different Animals See The World
Maybe you know, the ability of the eye as a sense of vision will decrease with age. Not surprisingly, many people experience decreased vision to blindness in their age. But wait a minute. The sharpness of eye vision does not immediately stop at productive age and continues to decline afterwards.In fact, the ability of the human sense of sight will continue to grow until it reaches middle age. Do not believe? See the following explanation.
At what age will the eye's ability as the sense of sight be best?
Many consider that the development of seeing abilities only occurs in the first five years of life and will stop completely afterwards. However, the facts found by experts from McMaster University are different. In a study published in the Journal of Neuroscience, it was found that the quality of the human sense of sight did not stop there.
Of the 30 study participants consisting of 12 women and 18 men, the researchers concluded that parts of the brain that play a role in perfecting the ability to see, proved to continue to develop and ripen themselves after undergoing brain tissue examination. As a result, the sharpness of the eyes to see will continue to grow until the age of 40 years. What is the reason?
The sharpness of the eye to see is determined by brain development
The sharpness of the sense of sight which turns out to continue until the age of 40 is related to the development of areas of the brain that regulate the ability of the eye to see. The part of the brain that plays a role in the development of the ability to see someone is the primary visual cortex. This part of the brain belongs to the area of the rear cortex of the brain, where all the information obtained by the eye will be processed by this part of the brain.
So simply, when you see something, the eye nerve sends a signal to the part of the primary visual cortex and then that part of the brain will interpret the transmitted signal, so you know what object or event you saw at that time. So, if this part of the brain develops, the ability to see humans can increase.
The link between the development of the senses of vision and the treatment of lazy eyes
In this study it is known that the primary visual cortex continues to develop until a person is 36 years old. Not only the fact that was able to surprise the researchers, was also found the process of primary visual cortex brain development that occurs in humans.
There are five stages of development that occur in the primary visual cortex until finally this part of the brain stops.Therefore, these findings are considered to help patients suffering from amblypobia or lazy eyes.
Previously, experts considered that children who have passed the age of 5 years or adults who experience lazy eyes, cannot be treated completely. Usually, handling is only by using lenses - glasses or contact lenses - to help the ability to see normal.In fact, when viewed from the results of this study, there is still hope for adults who experience amblypobia. However, this still needs to be studied and further investigated.
