Farsightedness of 600 degrees is high hyperopia, which usually causes amblyopia. First of all, put drops of ciliary muscle paralyzing agent, dilate the pupil for optometry and then wear suitable hyperopic glasses. If the difference in vision between the two eyes is not much, cover both eyes alternately and strengthen vision training. You can do visual stimulator training and fine training, such as tracing red, tracing pictures, threading needles and beads, etc. In case of paracentral gaze, the Heidinger brush method or posterior image therapy, red filter method, etc. can be used to convert it to central gaze and then masking therapy. For patients over 4 years old, when binocular vision is equal and greater than or equal to 0.6, training of binocular vision is performed to consolidate the training of amblyopia.
