Functional lenses have some improvement effect on youth myopia, but the effect is relatively limited. Because functional lenses can adjust the visual perception with the environment, they can relieve eye fatigue. When patients use their eyes to watch the near place, they can reduce the adjustment force of their eyes, thus relaxing their eyes and avoiding the state of eye fatigue caused by long-term use of eyes, thus alleviating the deepening of the degree of myopia in adolescents due to eye fatigue. However, functional lenses are not a cure for myopia, and the suitability of functional lenses for a patient needs to be determined by the patient’s optometric screening. In addition to wearing functional lenses to relieve eye fatigue, patients also need to pay attention to eye hygiene, and if they use their eyes frequently, they can relieve eye discomfort through periocular massage, hot compresses and other ways. It is recommended that myopic patients consult a doctor in a timely manner to assess their condition and follow the doctor’s instructions for treatment.
