The vision of 0.5 is usually checked by an eye chart, while whether it is myopia and the exact degree of myopia need to be clarified by an optometry examination.
Visual acuity of 0.5 is generally lower than normal. There are many reasons for vision loss, including myopia, astigmatism, fundus diseases and other possibilities, which need to be examined.
If you want to know whether it is myopia and the specific degree, you should go to the hospital for an optometry examination to make it clear, and the first optometry usually needs to dilate the pupils to exclude the possibility of pseudomyopia.
If the vision of 0.5 is caused by myopia, it should be corrected in a timely manner according to the doctor’s advice, and after correction, attention should also be paid to maintaining good eye habits to prevent and control the progression of myopia.
