Myopia Control Lens Manufacturers

What Are the Principles of Myopia Control Lenses and How Do They Help Prevent Myopia in Children and Adolescents?

Myopia has become a common visual health issue among children and adolescents worldwide. With the widespread use of digital devices and reduced outdoor activities, the incidence of myopia is rising year by year. Jiangsu Green Stone Optical Co., Ltd., as a professional optical lens manufacturer integrating R&D, production, and sales, is committed to providing high-quality eyewear solutions for users of different ages. Among these, Myopia Control Lenses are one of our key research and production focuses, aiming to effectively slow down the progression of myopia in children and adolescents.

The core principle of myopia control lenses lies in Peripheral Defocus control and multifocal visual design. Traditional single vision lenses mainly correct central vision, while the peripheral retina of the eye may experience excessive focusing pressure during prolonged near work, stimulating axial elongation and accelerating myopia progression. Myopia control lenses are precisely designed on the front or back surface of the lens, so that the peripheral retina receives a mild "defocus signal," thereby inhibiting excessive axial growth. This scientific design not only ensures clear central vision but also effectively slows the progression of myopia, providing sustained protection for children and adolescents.

In terms of product types, Jiangsu Green Stone Optical Co., Ltd. offers various lens solutions suitable for myopia control, including multifocal single vision lenses, progressive lenses, and defocus-designed lenses specifically for children. Our lenses cover refractive indices of 1.499, 1.56, 1.60, 1.67, 1.70, and 1.74 and are treated with HC (Hard Coating), HMC (Multi-layer Coating), and SHMC (Super Hydrophobic Multi-layer Coating) to ensure scratch resistance, anti-reflection, and anti-smudge properties, enhancing wearing comfort and visual experience. Whether in outdoor activities or study environments, children wearing our myopia control lenses can achieve clear vision and scientifically regulated retinal focus.

Scientific research shows that myopia control lenses have a significant effect in slowing down the progression of myopia in children.
