Abstract
Disclosed embodiments include means and methods of automatically measuring numerous characteristics of an optical system, such as an eye. Measured or displayed optical properties may include but are not limited to. spherical power, cylinder and axis for astigmatism. Higher order optical aberrations may also be measured. Disclosed embodiments may be used to measure refraction for creating corrective lenses for eyeglasses and contact lenses. Measurements of higher order aberrations of an eye may be used for measuring enhanced correction, accommodation state and range.
