Q1: Which factory produces Uno lenses? How is your strength?
A: Uno Multi Point Defocus Lens is independently developed and produced by Jiangsu Dongbao Optics Co., Ltd. The factory was established in 1995 and has been deeply involved in PC lenses for nearly 30 years. It covers an area of 6000 square meters and is a professional manufacturer integrating PC lens research and development, production, and sales.

The annual production capacity of the factory can reach 6 million pairs of PC lenses, and since 2007, it has maintained stable cooperation with VE, a professional lens manufacturer in the United States with a history of 150 years; Through ISO9001:2015 quality management system certification, the product meets the dual standards of EU CE and US FDA, as well as export grade quality standards.



Q2: What is the difference between PC lenses and regular resin lenses? What are the advantages of Dongbao PC raw materials?
A: Ordinary resin lenses have weak impact resistance, are prone to yellowing, and have poor UV blocking ability;
Our company's PC lenses use imported first-class optical PC raw materials:
Lightweight texture, extremely strong impact resistance, higher safety, and more protective for teenagers to wear;
The raw material is naturally resistant to UV380 ultraviolet rays, providing long-lasting sun protection and preventing oxidation and yellowing;
Less impurities in the lens and excellent basic transparency performance;
Paired with imported molds, the lens has uniform curvature and no internal stress, and there will be no appearance defects such as orange peel or pockmarks.



Q3: How does the Uno multifocal lens control the deepening of myopia?

A: The lens adopts a biomimetic youth eye curvature design, with 534 multi-point microlenses on the surface and a defocusing amount of+400 non spherical design:
The central area of the light forms a normal image on the retina, ensuring clear daily vision;
The light in the microstructure area is focused in front of the retina, forming a stable competitive myopic defocus;
The gradient on the back surface of the lens increases the peripheral defocus, which can also maintain effective defocus when reading or writing at close range;
Even if the eye rotates, the micro lenses in any area of the lens can continue to work, delaying axial growth and slowing down the rate of myopia progression.



Q4: What do 534 microlenses represent? Is the defocusing effect guaranteed?

A: 534 uniformly distributed micro lenses cover the entire visible area, which is different from sparse micro lens lenses. Whether looking far, close, or turning the eye left or right, it can continuously form effective myopia defocus without defocusing discontinuity, and the myopia management effect is more stable and balanced.
