Eyes - the windows of the soul, glasses are installed in the “window” on the glass, while glasses is the treatment of eye diseases, refractive correction of medical supplies, if the glasses failed what will happen? Unfavorable inferior glasses to people Have the following effects: ① eye fatigue, dizziness, wearing glasses time can not be too long; ② cause the regulation of eye muscle burden, especially when the refractive power of glasses and optometry prescription far more prominent, ③ prism effect caused spin, Nausea, poor balance, depending on the ground, uneven buildings, bending section discomfort; ④ unqualified vision, loss of correction, the purpose of treatment. Caused by the above symptoms and the relationship between the glasses as follows: ① glasses are not allowed to refraction, optometry prescription than the high or low belong to this category; ② optical prism produced by ultra-prism effect; ⑧
