Abstract

The invention relates to cylindrical tunable fluidic lenses. The cylindrical optical power of the lenses may be continuously tuned within at least ±10 diopters, without inducing any significant spherical aberration, or any other significant aberrations. The lenses feature a geometry that produces minimal or no spherical defocus. These cylindrical tunable fluidic lenses could be used to induce and/or correct cylindrical optical aberrations in adaptive optical systems, particularly in ophthalmologic applications related to objective and automatic assessment of the refractive error of the eye, without the need of receiving feedback from the subjects.
