Jiangsu Dongbao Optical Co., Ltd.
SINCE 1995
Jiangsu Dongbao Optics Co., Ltd. was founded in 1995 and is located in the Development Zone of Danyang City, Jiangsu Province, covering an area of 6000 square meters. It is a professional manufacturing enterprise with nearly 30 years of history in China that integrates research, development, production, and sales of PC lenses. There are various products available, including myopia, presbyopia, high dispersion, dome dual light, 70mm diameter presbyopia, semi-finished products, anti blue light lenses, progressive lenses, polarizers, etc.
Our company has passed the IS09001:2015 quality management system certification, and our products comply with the European Community C. Our company has a complete set of advanced thermoplastic PC lens production lines, and the raw materials used are Japanese origin PC materials. The product is light in weight, strong in impact resistance, of good quality, with few impurities, and the material properties are resistant to UV380. It effectively resists UV rays, is not prone to yellowing, and has good light transmittance. Since 2007, we have been cooperating with VE, a 150 year old lens manufacturer in the United States, and 80% of our products are sold to the North American market. Annual production of 6 million pairs of PC lenses.

Dongbao PC Lens Core Advantages
Polycarbonate material | Safe and high-performance optical lenses
High quality imported raw materials
The raw materials used are imported first-class optical PC materials from abroad. The products produced are light in weight, strong in impact resistance, low in impurities, and have UV380 resistant material properties. They effectively resist UV rays, are not prone to yellowing, and have good light transmittance.
Imported precision molds
Our company's molds are imported from abroad, and the products produced have good appearance quality, stable curvature, no internal stress, and will not have any problems; Orange peel; Appearance defects such as pockmarks.
Patent hardening process
The lens hardening technology adopts patented technology, and the unique hardening technology makes the product highly wear-resistant, scratch resistant, high-definition, dust-free, and easy to clean. The fully automatic hardening production line ensures the stability of the product.
Solid coating process
The lens coating process ensures that one surface is coated for 30 minutes, and after boiling test, the film layer is firm and does not fall off. The ultra waterproof film increases wear resistance while being dust-free, clean and transparent, and anti fog and anti fouling.

Advantages of Full Chain Process
Our company excels in raw materials, molds, cleaning and hardening, optical indicators, and coating processes compared to other similar products, overcoming the long-standing problem of lens quality in the domestic and international PC lens processing and manufacturing industry, and bringing more business opportunities.
Principle of multi-point defocusing lens technology
Multi point defocusing characteristics | Principle of cross-sectional optical imaging
Multi point defocus characteristic
- The concept design of biomimetic management for the unique curvature and center defocus of adolescent eyeballs.
- All 10mm focal area light falls well onto the retina, achieving visual delay and ensuring clear imaging.
- 534 multi-point microlenses effectively slow down axial growth and reduce myopia progression. The defocus amount+400 non spherical design lens hardening technology adopts patented technology, which is wear-resistant and anti scratch, making the lens more durable and hard.
- The front surface of the lens adopts a microstructure design, which enables the light passing through the microstructure to focus and image in front of the retina, forming competitive defocus. The back surface of the lens gradually increases the defocus amount, forming peripheral defocus and improving the defocus amount when viewing objects at close range.
Principle of cross-sectional imaging
- The surface of the multi-point micro lens defocusing lens adopts a 534 point micro lens defocusing design, which can form a clear image on the retina while continuously creating a special optical state of myopia defocusing in the eye.
- When the wearer's eyes turn to different areas on the lens, the micro lenses in this area will come into play, allowing the lens to continuously provide myopia defocus without being affected by eye rotation.
