Frequency contact lenses cover all basic types of contact lenses for different eyes. Our selection of Frequency contact lenses includes various monthly replacements, and this includes the standard Frequency 55 and 38 contact lenses. For specific eye conditions, we have Frequency 55 toric contact lenses, as well as multifocal and aspheric lenses. As the latter type of lens suggests, Frequency aspheric lenses aren’t rounded contact lenses but, instead, flatter and thinner lenses. For the wearer, this often means more comfort in wearing the lenses and the lenses distort the appearance of the eye, giving the pupils a larger appearance.
