Do teenagers need to wear glasses often? First, mild myopia (-3.00D or less) patients to see the distance (such as classes, watching TV) need to wear glasses. They may not wear them when they are near. Two, medium and high myopia is usually accompanied by astigmatism, need to wear glasses to see far and near. Patients with astigmatism (+1.00D or above) should, in principle, often wear lenses. Fourth, farsighted patients need to wear glasses regardless of distance and near. Some myopic friends are worried that myopia will deepen after wearing glasses, and they can’t take off their glasses later, this concern is not based on science. The deepening of myopia after wearing glasses is mainly related to the lack of attention to eye hygiene, the anterior and posterior diameters of the eyeball become longer and thicker, and has little to do with the frequent wearing of glasses. After adulthood, the refractive error state is gradually stabilized, and the degree of change will be very small or no longer deepen. With the continuous development of medical science and technology, excimer laser surgery can be performed in adulthood to remove eyeglasses.
