Our Lens Quality

Many customers around the world have praised our products, noting that both finished and semi-finished lenses match the specifications in our catalog.

While it may seem straightforward for lenses to align with the catalog, producing plastic lenses with precise base curves through the cooling and heating of monomer is quite challenging.

As a pioneer in the field, we boast extensive experience and a wealth of knowledge in manufacturing Plastic High Index lenses.

Our fundamental mission is to enhance people’s vision through our lenses, thereby contributing to a better quality of life worldwide.
