Prefix and South township Dahua Village elementary school students in agriculture have ear, a pair of wonderful eyes
######y lingerie, the pupil is blue, blue-light irradiation is also given the green light. Moreover, he has an amazing ability, pitch-dark place, able to clearly read and write, and the same day. As the villagers said, he is like a long This in the end is how the case?
inherently magical pair of the same. Finally, his father took him to the county hospital seen, when the doctor said it does not matter, so after growing up, slowly enough.
farmers grew up with ear
lace corset top, the eyes are still blue, without any changes, but neither pain nor itch, nothing uncomfortable performance, visual acuity are also normal, and gradually people are not home care of.
instant agriculture has ear length to 8 years old, the elementary school. The first day of school, he attracted the attention of class teachers. At first, the teacher thought something wrong with his eyes, afraid of him to see the blackboard, specially arranged for him to sit in the front row. However, farmers do not like sitting in the front row with Spike, he found the teacher, offering to change to the back.
farmers have ear lively personality, likes and small partners to play together, and we do not feel any different. However, a long time, head teacher or found in his different. If you are outside, the sun a bit stronger in this respect, we see things are normal, but farmers have been narrowed eyes spike a crack, blurred vision, to see clearly. Teachers find it strange that the child at night, vision what? Results farmers should catch the ear with the students at the cricket, everyone with a flashlight, only he did not take, he said he could not see the torch. Students use a flashlight as he could not help are afraid, and have said that his eyes are cat's eye. Gradually, we all began to feel a spike in the eyes of farmers is different.
father began to pay attention to agricultural official Chinese children. He found that farmers have always liked to spike usually dark corner, or a dimly lit place, but still see things clearly, and issued a coldness in his eyes, do a bit of the pool. Moreover, children like to go out at night, Shino dark, pitch-dark, rugged mountain, he ran fast and never afraid of falling.
village people talking about this matter, a superstition that quietly spread: this child is a cat to be reborn, so only a pair of eyes for so long.
do, farmers are really cat ear, a magical night vision capabilities?
night vision has been tested
from that time
bandage dress, farmers have the ear
nocturnal cats, cats with the same tiger, lion, leopard, like the, there is a striking characteristic, that is the eye: the night depending on the material as light as day, but also shining , as the gem. Cat's eyes, there is a layer of reflective film, composed by the zinc metal elements, like the side of the reflective mirror, even if very faint light, can also be captured and re-reflected to the retina, and more to improve night vision capability, which cat eyes glow is the main reason.
of Veterinary Medicine, China Agricultural University, said Professor She Ruiping: cats more developed rod cells can reach the million, just over a hundred human beings. Therefore, the light in the dark, cats can see objects, depending on the material capacity is relatively strong. And human, although in the faint light can also see some things, but the basic outline is very fuzzy.
, however, why the farmers are different from normal eyes, ear, depending on the material in the dark it?
this time went with Dr. Song Jiang tell their own judgments: completely dark because no light, he can not see the words on paper. And when the roof a little faint light get through, he can see the words on paper.
But Dr. Song Jiang was acknowledged that the child's dark adaptation is particularly high, far beyond the average person. usually people from the day suddenly into a dark room inside, you will find not see anything, but after a few minutes spent on the inside, will gradually see the surrounding outline of some objects, called dark adaptation. such a person in a dark cell for long-term relations, he will greatly enhance the ability of dark adaptation. There is something called light adaptation. For example, in the earthquake, and was buried the wounded carried out to be blindfolded, and that is because they already have dark adaptation, the pupil is also more freely large, fierce glare of a received stimulation, ranging from short-term blindness, whole body paralysis, while in permanent blindness.
So, farmers should spike in the end it is a situation to which they belong?
experts expose lack of pigment cells on the iris, the pupil so that he looks blue. Western blue-eyed white iris pigment cells is relatively small, and farmers have ear eyes, not only the lack of iris pigment cells, and even on the back of the retina pigment cells are not. Farmers have felt spike in outdoor glare during the day is for this reason.
under the fundus image, the experts confirmed that farmers are suffering from a spike is a type of congenital ocular albinism.
Lu Linde director
corset lingeries, said: lack of pigment cells occurs only in the eye, the rest of the body are not. adapt faster, more comfortable and sensitive, but should not increase the dark vision. In order to confirm their own judgments, he arranged to have ear farmers do vision tests. First, clear vision, the results of a spike of agricultural vision 1.0. and then, off off light, in complete dark room, dark visual inspection and found that farmers are difficult to properly identify ear.
But Lu Linde also said that farmers should be more accustomed ear dim light, as the objects, and more than ordinary ability to adapt to these, so in the dark to see the ability to do something stronger than average.
according to people on the cats and other nocturnal animal studies, these animals act in the dark, in fact, need some trace of light. their special retina can turn the light brought together, to improve the utilization of light to increase the night vision capability. This is very similar with the farmers should spike.
just that, farmers have a special ear Mask is a doctor that is a congenital genetic defect, the present no effective medical treatment, only to wear sunglasses in bright light, avoid direct light stimulation. But let farmers have ear comfort the father is The sick will not have the ear of farmers adversely affect growth and development. (According to key：
