With the rapid development of modern technology, the problem of myopia in children is becoming increasingly prominent. Faced with a wide variety of children's eyeglasses products on the market, as well as defocus lenses, which serve as a defense in the lens industry, parents often struggle: should they choose regular glasses or defocus lenses for their children?

Regarding myopia, from a physiological perspective, what changes have occurred in our eyeballs from normal to myopia? Simply put, the main cause of myopia in children or adolescents is an increase in axial length.

Ordinary childrens eyeglasses, as the name suggests, are traditional glasses used to correct vision. It improves vision problems by changing the angle of refraction of light, allowing it to accurately focus on the retina. So, its main function is to correct vision, allowing people to see clearly after wearing it.

Defocus lenses belong to functional lenses. Through special optical design, defocus lenses not only project images from the central vision onto the retina but also project their periphery onto or in front of the retina, forming peripheral myopic defocus. By using defocus images, axial growth is suppressed and myopia deepening is delayed.

The biggest difference between defocus glasses and regular glasses is that regular lenses correct myopia, while defocus lenses not only correct myopia but also control the development of myopia and delay the progression of myopia.

Wearing lenses provides high comfort, which is why children are willing to wear children's eyeglasses frequently. Only when children persist in wearing them can they achieve better myopia management results.

Adopting a shell-shaped central visual area design, this design is more in line with children's eye habits of horizontal switching and less up and down rotation. Compared with the cylindrical central area design of the lens, the design improves wearing comfort.
