A wetness-retaining ophthalmic lens material comprises an organic monomer, a cross-linking agent, an initiator, a salt, and a solvent. The salt dissolves in the water dissociates a plurality of anions and cations, which bind to water molecules and retard the evaporation of the water molecules, the ophthalmic lens material thus can keep wet for a long time. An ophthalmic lens made of the ophthalmic lens material is also provided.

Also provided are methods of inhibiting APOL1 and methods of treating an APOL1-mediated disease, disorder, or condition in an individual.

Certain phosphonic acid salts heated at temperatures over 200 C. generate thermally stable, highly efficient flame retardant materials well suited for use as flame retardant additives in polymers. Various methods for preparing flame retardant materials from more than one phosphonic acid salts are provided, wherein each method can generate different flame retardant materials from the same mixture of starting phosphonic acids. The flame retardants of the invention can be used as the sole flame retardant in a composition or in combination with other flame retardants, synergists or adjuvants.
