Abstract: The present invention relates to technology for, among other things, administering, and analyzing the results of, ophthalmic examinations. The technology involves generating a display on a display device to enable a first ophthalmic exam to be administered, receiving a request for results of a second ophthalmic exam, requesting the results of the second ophthalmic exam from a data source, receiving the results of the second ophthalmic exam from the data source, displaying the results of the second ophthalmic exam on the display device and enabling annotation or modification of the results displayed on the display device.

Abstract: An ophthalmic dial advancement system for vision testing apparatuses, such as ophthalmic refractors of the type which utilize a single dial sphere control for advancing the lens power of at least one of the lenses positioned within the lens housing. A rotation element is positioned adjacent a portion of the engagement surface of the single dial sphere control so as to facilitate a controlled and sensitive advancement of the single dial sphere control and, in turn, the lenses which are being rotated thereby. A rotation disengagement member is operably attached to a portion of the lens rotation element so as to enable alternatively engaged and disengaged advancement of the single dial sphere control.
