title: Spherical aberration of a hydrogel contact lens when measured in a wet cell.
abstract: A method is given for calculating the spherical aberration induced when the power of a hydrogel contact lense is measured in a wet cell. Application of the method to measurement of contact lenses with varying power over the entire optical zone is included.
