There are many brands on the eyeglass mart that produce lenses for managing myopia in teenagers. The principle behind these lenses is simply to add defocusing lenses around the edges of the lens so that the degree of the lens is lower than that in the central area.

This allows the center of the line of sight to be corrected and accurately imaged on the retina, while the surrounding line of sight can also fall in front of the retina.

The child uses ray tracing technology to capture eye trajectories due to their ability to switch between horizontal and vertical fields of view. Improved kid's eyeglasses online wearing comfort, making it easier for children's eyes to adapt and more willing to wear for a long time, resulting in better prevention and control effects.

To select a suitable defocusing lens with a larger defocusing area and better myopia management effect. Based on multiple validations of retinal imaging and defocus theory, increasing the defocus area has been proven to be an effective way to control axial growth. Multi-point myopia defocus axis control technology, through dense design arrangement, greatly increases the defocus area and more effectively controls the growth of the eye axis.

Thinner kids eyeglasses online lenses make it easier for children to wear. At the same refractive index, the higher the degree of myopia, the thicker the lenses. Some children wear glasses with lenses as thick as the bottom of a beer bottle at a young age, causing their noses to be deformed and their ears to feel extremely uncomfortable.

However, increasing the refractive index can make the lens thinner and lighter. Especially for children with high myopia, ultra-thin lenses are naturally more comfortable to wear.
