If you want to know whether you have myopia or not, you must go to the hospital for formal optometry. Because we know that myopia is not only true myopia, but also pseudomyopia. After the optometry examination to determine whether there is true myopia, the specific myopia is how many degrees. If it is determined to be true myopia, it is recommended to wear a pair of appropriate glasses, or wear a pair of appropriate corneal reshaping lenses, which can obviously achieve the effect of alleviating the growth of myopia. However, when comparing the two, the corneal reshaping lenses are more effective, with the disadvantage that they are more expensive. In case of pseudomyopia, more outdoor activities, good eye habits and eye hygiene, and the use of eye drops to relieve fatigue can restore the state of non-myopia.
