Fiber Reinforced Polymer (FRP) is also known as glass reinforced polymer (GRP). Traditional GRP is composed of high strength E-glass fibers impregnated with a variety of specialized proprietary resins.

Since clinical trials began in 2016, this system has delivered correct-strength glasses to over 500,000 people in 67 countries. Trained, local ‘refractionists’, assist in this process, and it takes approximately 15 minutes to deliver prescription glasses for less than $5 per pair.

Offered long glass fiber thermoplastic with 3x the strength of incumbent short fiber material without a need for retooling Facilitated lightweighting with a 50% long glass fiber PA66 thermoplastic that matched the performance of the incumbent metal part
