A subjective refractor apparatus for astigmatism testing allowing observation along an optical observation axis with an optical vision correction of variable power. The apparatus allows a patient’s use of a tactile input device to control the rotary movement of rotatable optical elements with cylindrical power, varying the angular position of the optical elements to adjust the total cylindrical power and orientation of the cylinder axis of the resulting optical system. The tactile input device is capable of receiving input in two or more dimensions, with each dimension of input controlling the rotary movement of a single cylindrical optical element to adjust the combined cylindrical optical power of the two optical elements. The optical elements position readings may be sensed by rotational position sensors and sent to an operationally connected microprocessor for interpretation and display.

A portable intelligent multi-function phoropter is disclosed. The phoropter comprises a casing, a plurality of control elements, two adjustable eyepiece modules, a plurality of micro motors, a liquid crystal display module, a control module and a power supply module. The casing of the present invention is small so that the overall volume is small, and it is convenient to carry and use. The present invention has many test patterns, so different vision tests can be performed. With the combination of convex lens and concave lens and the application of existing electronic components, the overall price is reduced. The invention satisfies the market demand for the phoropter.

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.
