Prevention and control lenses have a certain scientific basis and clinical effects, but they also need to be selected based on the specific situation of children and the advice of doctors.

Generally speaking, preventive lenses are more expensive than regular lenses and require more frequent replacement and inspection. Therefore, when choosing prevention and control lenses, comprehensive consideration should be given to factors such as children's visual needs, economic ability, personal preferences, and regular professional optometry and matching with childrens eyeglasses.

At the same time as visual correction, a peripheral defocusing effect is generated, which forms a relative hyperopia state in the peripheral area of the eyeball and inhibits the growth of the eye axis.

Different astigmatism/axial positions are used for far and near use, making the lenses more in line with the physiological characteristics of the eyes and the geometric optical requirements of far and near, ensuring a significant improvement in the visual effect of children's glasses. It also has an eye protection mode, which can effectively reduce harmful light damage and improve visual contrast in dark environments.

It can only slow down but cannot prevent the development of myopia. It is suitable for children who do not need money or have rapid myopia development and cannot develop good eye habits.

Corneal plastic lenses are a type of rigid, breathable contact lens that can be worn at night to change the curvature of the central area of the cornea and temporarily reduce myopia. They are a reversible non-surgical physical corrective treatment method. After removal during the day, it can temporarily provide clear vision and a wide field of view. Although corneal reshaping lenses can temporarily correct myopia, they cannot cure myopia. After discontinuation, the cornea will return to its original state.
