Contact lenses are precision-engineered ophthalmic devices used for vision correction, cosmetic enhancement, and medical treatment. The development and manufacturing of high-quality contact lenses rely on advanced monomers, polymers, and cross-linking agents that determine key properties such as oxygen permeability, water content, modulus, UV resistance, and surface smoothness.
J&K Scientific provides a full range of high-purity monomers, cross-linkers, initiators, dyes, and solvents used in contact lens R&D and manufacturing, ensuring stability, biocompatibility, and reproducibility.
