Etafilcon a. Acuvue 2 contact lenses are made from a moistureloving material called etafilcon A, which allows Acuvue 2 contacts to have a 42percent water content This high water content helps keep the lens moist and comfortable on the eye from insertion to removal at the end of the day.

During the 1970s, Frontier developed a new material (etafilcon A), and the company began making soft lenses Frontier was among the first in the US to take this material, widely used in Europe, and combined it with the lathe cutting process to produce soft contact lenses In 1981, Frontier sold the company to Johnson & Johnson. The lens material (etafilcon A) is a copolymer of 2 hydroxyethyl methacrylate and methacrylic acid crosslinked with 1, 1, 1trimethylol propane trimethacrylate and ethylene glycol dimethacrylate. The etafilcon A control lens resulted in corneal deswelling throughout the day as did the SH lens types Limbal hyperemia and endothelial bleb formation with all lenses were negligible, and noninferiority assumptions were met between the lens types for all outcomes.
