Abstract

A fixture 10 for use in refracting an aphakic eye over a properly patient fitted spectacles frame glazed with major spherical component lenses and placed in a position of use upon the patient. The fixture 10 having trial lens holders for right 34a and left eye 34b refraction suspended from a main supporting bar 16, is attached to rims of the spectacles frame for establishing a parallel relationship between the holders and the frame and provision is made for separately adjusting each right and left eye lens holder vertically and horizontally as needed for centering with a corresponding glazed lens. Refraction over the major lens in each case may be conducted with trial lenses placed in the respective holders. <IMAGE>
