What Is A Defocus Lens ?

Defocus, or out of focus, is when it should be in focus on the retina, but it's not. Focusing behind the retina is called faropic defocus, while focusing in front of the retina is called myopic defocus. Defocus is an important visual feedback signal that can alter the way the developing eyeball grows. If defocus is stimulated by wearing a lens during eye development, the eye will develop towards the position of the defocus signal to achieve ememification. Defocus glasses are a frame lens designed on the defocus principle of peripheral myopia. After wearing this lens, the object will form the defocus of peripheral retina in the eye. The defocus image can be used to control the axial growth of the eye and delay the deepening of myopia, which is one of the effective means to control the deepening of myopia that has been proved clinically.
