Control myopia, not only control the degree! Our center fully controls the increase of myopia for school children. We measure the length of the pupils' eyes (eye axis), whether they have myopia or not, so that parents can better understand the development of myopia. After using the OK mirror, I believe that many parents want to know, has the degree of their children increased? You don't have to stop wearing glasses to know the results. Through the development of the eye axis, we know the control efficiency of the OK lens, which is more scientific and more careful! If you want to know more, please contact us at 2302-1898!
