The child's eye health is very important, because it is related to future vision problems, many parents will fool the vision report, and many people directly can't understand it.
If the vision is not up to standard, as far as possible to the doctor on the rash, vision report includes vision and diopter two parts of the results, the standard is to measure the distance in 5 meters, whether you can see the ability to distinguish the shape and size of the object, of which 1.0 is the standard vision, but the report is expressed in 5.0.
For different ages, the vision standard is different, generally 1-year-old children's vision can reach 0.2, 2 years old just reached 0.4 and above, 3 years old can reach 0.5 and above, 6 years old is 1.0 and above, not up to the standard indicates that there is a problem with vision, and further reasons need to be found.
The diopter is more complex, including three parts, spherical mirror, column mirror and axis position. Spherical mirror, is the degree of myopia and farsightedness, myopia is expressed by negative numbers, farsightedness is expressed by positive numbers, column mirror is the degree of astigmatism, generally expressed by negative numbers, -2.25 is astigmatism 225 degrees. Axis positions only indicate direction, there is no distinction between sizes.
Under normal circumstances, people are born with farsightedness, with age, eyeball development, farsightedness will be reduced, about 10 to 12 years old to 0 ~ 50 degrees to achieve positive vision, when the child's diopter test results are not in the above range, it is necessary to pay attention to, generally within 50 degrees of astigmatism has no obvious impact on vision, no special treatment, do not worry, when the astigmatism exceeds 75 degrees, vision may be affected.
For the sake of children's vision health, please pay attention to protecting your eyes.
