What is a peripheral defocus lens?

Peripheral defocus lens is a lens worn by multifocal glasses, which is used for patients with hyperopia and esotropia. The lens with stable degree and defocus can change hyperopia around retina into myopia defocus, thus inhibiting axial growth.

Two things with different concepts, one is bifocal lens and the other is multifocal glasses, but the principle is not much different.

Two things with different concepts, one is bifocal lens and the other is multifocal glasses, but the principle is not much different. For most patients, the effect is average, and this kind of glasses is only suitable for patients with excessive aggregation and esotropia. In real life, such customers are rare, accounting for less than 10% of all myopia patients.

Extended data:
