Contact lenses, also known as corneal contact lenses, are ophthalmic repair equipment used for vision correction, beauty, treatment, etc. They are usually made from silicone hydrogel, water and polymers (methacrylates).
The development and manufacturing of contact lenses relies on new high-quality monomers, polymers and other reagents. Monomer selection can affect contact lens properties such as modulus, permeability, surface finish, UV absorption, resistance to tearing, and surface defects.
J&K Scientific offers a variety of high-purity monomers and polymers, as well as a full range of initiators, cross-linkers, dyes and solvents. High-quality products, a wide selection, and excellent service help contact lens manufacturers develop new products quickly and successfully.
