Zeal Optics launches plant-based lens

Zeal Optics has released what it described as the world's first plant-based lens.

The new e-llume lens, which uses a plant-based bonding agent instead of a petroleum-based bonder, was said to uphold the highest of optical standards for quality and clarity, while minimising the impact on the environment.

With the release of the new lens, the manufacturer said it had bolstered its green credentials. It currently manufactures all of its sunglass frames with Z-resin, a plant-based material that uses castor oil which eliminates harmful crude oil from the manufacturing process. The release of the new lens removes the use of crude oil completely.
