An eye exam is a comprehensive eye exam designed to comprehensively assess the various functions of the eye. It is not limited to checking eyesight, but also includes a range of other tests of visual function. These tests cover a wide range of areas, from simple vision tests to more complex visual field and color examinations.
Yang Ming Vision is here to answer your questions, children's vision development is a complex and delicate process, which gradually improves with age. The functioning of the nervous system plays a crucial role in this process. As children grow, their nervous system matures and their ability to perceive and regulate light improves.
The process of visual development is slow in childhood, and visual function is gradually developed and perfected by external stimuli. 0-6 years old is the first period of vision development. Vision development is basically fixed by the age of six or seven, so vision care in early childhood is very important and must not be ignored. The eye chart can be used to check the eyesight, and only by checking the vision frequently can the changes in vision be detected in time, and interventions can be taken as early as possible.
At present, the international standard eye chart is generally used for eye examinations
1. In the eye examination, it is very important to ensure that the person being examined keeps an appropriate distance from the eye chart. Usually, the eye chart should be placed at a distance of 5 meters from the person being examined. However, if the space in the room is limited and this requirement cannot be met, we can take another approach, which is to be opposite the eye chart2A flat mirror is placed at 5 meters. In this way, the examinee can see the eye chart from the mirror, thus achieving the same effect as a direct eye chart.
2. The light source of the eye chart should be fixed to avoid affecting the test results due to changes in the light source. Finally, the brightness should be constant artificial lighting to ensure the stability and consistency of the test environment.
3. When performing an eye examination, both eyes are usually examined separately. First, we will examine the right eye, then the left eye. At the same time, we will cover the contralateral eye with the concave side of the eye barrier to ensure the accuracy and objectivity of the examination.
Emphasis is placed on vision screening for preschoolers
When babies are born, most of them are farsighted. At birth, the eyeball is not fully developed, and most of the eye axes are short, so most babies born are farsighted. As we age, our eyeballs are also gradually changing. As the eyeball grows larger, the axis of the eye becomes longer, just like the rest of our body matures. And in the process, our farsightedness is also gradually decreasing, which means that our eyes are gradually developing from farsightedness to emmetropia. The process of emmetropia is completed around adolescence. During this period, our bodies are undergoing many changes, including the development of height, weight, muscles, and bones, among others. The completion of emmetropia also means that our eyes have matured and are better able to adapt to different visual needs.
However, it is important to note that while emmetropia is a natural physiological process, any problems or abnormalities present during development** can lead to vision problems or other health problems. Therefore, we should maintain a healthy diet and good lifestyle Xi while having regular eye exams to ensure our eye health and prevent any potential problems.
