The eye is the window of our mind and one of the most important organs of the human body. Once the eye has a problem, it will have a great impact on our lives, so we must take strict care of the eyes and keep them in a healthy state at all times. In order to help everyone find some eye diseases in time and achieve "early detection and early treatment", today Xiaoduo will provide you with several pictures that can quickly test eye diseases, through these pictures, it can help us make a preliminary judgment.
Myopia test chart
In the naked-eye state, do you see an old man with white hair, or a sexy woman? People who are not nearsighted see white-haired old men; nearsighted people see sexy women.
Considering the distance of the myopic person, the diopter is not the same as the diopter is not the same. When identifying this figure, people need to maintain a certain distance, computer users are recognized at a place of about one meter or so, and mobile phone users are recognized at a place of about 60 centimeters.
If your child sees a sexy woman within this distance, then Xiaoduo recommends that parents should pay attention to whether their child has recent symptoms of myopia, or take their child directly to the eye clinic for examination.
Astigmatism test plot
At a distance of 30 cm from the picture, cover one eye with your hand and gaze at the chart with the other eye in a naked eye state, and then repeat the above process, test the other eye, what are you looking at?
If it is A, it proves that there is no astigmatism; if it is B or C, there may be astigmatism, it is recommended to take the child to the doctor in time.
Color blindness test chart
In the picture above, what animal are you seeing? Is it a deer or a cow?
If it is a cow, it proves that you have normal vision; if it is a deer, it proves that you have red-green blindness. Although color blindness has no impact on health and vision, many majors cannot be studied, such as fine arts, textiles, printing and dyeing, chemical industry and other majors that require visual sensitivity. Children are at a critical moment in studying and choosing a major, and if the child is colorblind, parents should prepare early.
Of course, simply relying on pictures to test is not very accurate, plus there are many kinds of eye diseases, many eye diseases in the early stage without warning, once the onset of the disease may lead to blindness. Therefore, if you want your child's eyes to be healthy all the time, the best way is to take your child to an eye hospital or clinic after the child is three years old, and establish a special refractive development file.
The refractive development file is a file of the growth and development of the eye, which records the important parameters of the eye, such as visual acuity, diopter (myopia, hyperopia and astigmatism), corneal curvature, eye axis length, etc. After the establishment of refractive development files, doctors can not only find out whether the child has myopia, strabismus, amblyopia, cataracts and other eye diseases in time according to the changes in parameters, but also predict in advance whether the child has the possibility of suffering from myopia, and intervene in advance to prevent the occurrence of myopia.
