  • Basic information

Overview

Made from plant-derived materials, this lens is designed to create a smaller carbon footprint than conventional petroleum-derived products.

Properties

Plant-derived materials

Based on LCA (Life Cycle Assessment), this material reduces greenhouse gas emissions by 14 % compared to conventional products based on petroleum-derived materials.*1
The resulting products are JORA- and USDA-certified biomass products.*2*3

Superior Optical Properties

This material allows the production of high-quality lenses with less distortion, with optical performance levels comparable to conventional products made from petroleum-derived materials.

Ultra-High Refractive Index

The extremely high refractive index of 1.74 allows the manufacture of much thinner and lighter lenses, even lenses with high corrective power.

*1 Based on our Life Cycle Assessment (LCA) procedure

*2 JORA certification: Biomass mark indicating certification by the Japan Organic Recycling Association of environmental products recycled from bio-based resources (biomass), which satisfies applicable quality regulations, standards, and criteria

*3 USDA certification: Biomass mark indicating certification by the United States Department of Agriculture of plant-derived products (USDA BioPreferred®)
