Outcome results
Spherical Aberration Measurement
Spherical aberration (SA) occurs when light rays entering at different points of a spherical lens are not focused to the same point of the optical axis.
Time frame: 60 minutes
Population: 30 eyes wore the +3D, 0D, -3D, -6D, and -9D contact lenses. 26 eyes wore the +6D contact lenses.
