GM Advance 58

Filcon II 2 / Acofilcon A – water-60%

GM Advance is a refined blend of purified monomers that helps achieve high manufacturing yields. Its durability guarantees patient satisfaction and low lens breakage levels, while also having great on-eye stability and water retention.

GM Advance 49 has a lower modulus, higher tensile strength, and higher elongation-to- break than other GMA based materials. It has unique material blends to ensure superior lens surfaces and edges and resists dehydration longer and rehydrates faster than comparable materials.
