Abstract: in recent years, the incidence rate of myopia has been increasing in adolescents. However, many parents have misunderstandings in adolescent eye care and optometry. Ophthalmologists remind that children with myopia should wear glasses in time and develop good living habits to avoid deepening the degree., Many nearsighted patients often feel tired after wearing glasses. In addition to the factors of inaccurate glasses, ignoring the correction of astigmatism is also an important reason., Myopia and astigmatism are not the same thing, but often many myopia patients suffer from a certain degree of astigmatism at the same time. Astigmatism leads to ghosting when looking at things. If there is no good correction, the eyes will constantly adjust to seek the best focus, resulting in blurred vision, descent, eye fatigue, torticollis, etc., Some myopia patients like to add astigmatism degree to myopia degree, such as three Baidu myopia and one hundred degree astigmatism. In order to “save trouble”, some patients often directly buy a pair of four Baidu myopia glasses, especially when buying contact lenses with poor astigmatism correction, many people choose this superposition method or simply correct myopia degree., With glasses astigmatism “width =” 400 “height =” 300 “SRC =” / / img should never be ignored jianke. com/article/201509/2015090817201745. Jpg “/ >, in fact, whether it is to correct myopia or astigmatism, it is necessary to match appropriate glasses through medical optometry. Through medical optometry, it is not easy to have “over correction”, and the glasses are most suitable for ordinary needs. The correction of astigmatism is more complex. Only knowing the degree is not advisable to buy glasses in the optical shop according to the degree. Accurate optometry should be carried out to obtain specific astigmatism types and parameters, so that the glasses can effectively correct astigmatism and avoid visual fatigue caused by astigmatism., Rigid contact lenses that can only be checked and matched in ophthalmic hospitals are contact lenses that can correct astigmatism, especially high astigmatism, which can also be effectively corrected by RGP., How to judge that you have astigmatism?

many myopia patients often feel easy to see fatigue after wearing glasses. In addition to the factors of inaccurate glasses, ignoring the correction of astigmatism is also an important reason.
myopia and astigmatism are not the same thing, but often many myopia patients suffer from a certain degree of astigmatism at the same time. Astigmatism leads to ghosting when looking at things. If there is no good correction, the eyes will constantly adjust to seek the best focus, resulting in blurred vision, decline, eye fatigue, torticollis, etc.

are hard contact lenses that can only be checked and matched in eye hospitals. RGP is a contact lens that can correct astigmatism, especially high astigmatism, which can also be effectively corrected by RGP. How can
and
judge that they have astigmatism? The following characteristics can be used as the basis for self-examination of astigmatism. Of course, it is best to conduct medical optometry in an ophthalmic hospital to obtain accurate refraction:
1. When looking at things, you often feel blurred or have double shadows.
2. Often half close your eyes and narrow them into gaps. It seems that you can see more clearly in this way.
3. Eyes are easy to fatigue.
4. You will feel headache after reading for a long time.
5. The vision at night is worse than that during the day.
