Abstract: Provided are ophthalmic components (e.g., eyeglass lenses and contact lenses) that include a two dimensional crystalline solid material dispersed in a matrix material. The disclosed components can selectively filter light of selected wavelengths, thereby making the components suitable for use by individuals who may suffer from color vision deficiency conditions. The two dimensional crystalline solid material comprises at least one layer comprising a substantially two-dimensional array of crystal cells; each crystal cell having an empirical formula of M(n+1)X(n), such that each X is positioned within an array of M, wherein M is at least one Group IIIB, IVB, VB, VIB or VIIB metal, and wherein X is C and/or N.
