If your eye prescription is 150 diopters longer than before, you need to change your eyeglasses. If your eye prescription is 150 degrees higher than before, it means that your refractive error is gradually deepening. One of the purposes of wearing eyeglasses, besides relieving eye fatigue and correcting refraction so that you can see objects clearly, another important role is to prevent the adjustment and collection functions of the eyes from losing balance. Therefore, after suffering from refractive error, if your eyes become more discerning, you need to change your eyeglasses in order to avoid further imbalance of the adjustment and collection functions of your eyes. If you change your glasses in time, you can avoid further aggravation of the refractive error and other problems such as strabismus. After wearing eyeglasses, it is still necessary to pay attention to eye hygiene and not to use the eyes excessively for a long period of time. After using your eyes for a period of time, you should pay attention to rest and relaxation, go to the ophthalmology department regularly to check your eyesight, and cooperate with the doctor for treatment if necessary.
