Defects of Adolescent Progressive Lenses
Long-term use of progressive lenses will cause a deficiency of binocular physiological regulation in adolescents. Long-term use of progressive lens may lead to ocular muscle imbalance in both eyes of adolescents. After wearing a progressive lens, part of the field of vision is not clear, which will affect the activities of young people. After wearing the progressive lens, when walking downstairs, riding a bicycle, and doing various sports, you need to see through the near area under the lens to see far, which will affect your activities due to blurring. It is not comfortable to wear a progressive lens to look at an upright screen such as a computer, and the refractive power of a progressive lens in these parts is different. To see the screen clearly, it is necessary to adjust repeatedly, which is easy to cause adjustment disorders and visual fatigue, even dizziness, and eye pain.

Aspheric lenses are different from spherical lenses.
Spherical lenses: The higher the strength of spherical lenses, the worse the visual experience, because the spherical lenses do not eliminate aberrations. Aspheric lens: it can greatly reduce the deformation of things and make people see more clearly and vividly. Besides, the eyes are not easy to get tired and the appearance is beautiful. It reduces the aberration of the lens and ensures a clearer field of vision.
When the parameters of the lens are normal, the optical center of the myopic lens is the clearest, and the peripheral part of the lens will be slightly deformed. So now the lens is designed with an aspheric surface. Under normal circumstances, the mainstream aspheric lens in the market has a reduced edge design, which is about 5 to degrees lower. The opposite edge of a spherical lens is higher.
