An ophthalmic measuring instrument to be detachably connected to the eyeglass frame of a patient in front of the lens area in said eyeglass frame comprising, a. an instrument frame having a front, a back, spaced eye viewing openings and a medially disposed nose opening, b. clip means on the back of said frame for detachably connecting the instrument frame to the eyeglass frame of the patient so that the eye viewing openings are disposed substantially in front of and in alignment with the lens area of said eyeglass frame, c. first and second vertically disposed transparent colored strips adjustably connected to the instrument frame to permit indexing of each of said strips in front of an associated one of said eye viewing openings, d. first and second horizontally disposed transparent colored strips adjustably connected to the instrument frame to permit indexing of each of said strips in front of an associated one of said eye viewing windows in intersecting relation with an associated one of said vertically disposed colored strips, e. the respective first and second horizontally disposed transparent colored strips having a color which causes a perceptive color change to the patient when the associated transparent colored strips bisect the visual axis of the patient's eye being measured, f. graduated upper markings on the front of said frame having a center point to enable the said frame to be aligned with the center of the eyeglass frame to which it is attached and operatively associated with the first and second vertically disposed transparent colored strips to enable an MVA distance measurement to be made whenever either of said vertically disposed transparent colored strips bisect the visual axis of a given eye of the patient, g. a first and second set of graduated markings on the front of said frame operatively associated with the first and second horizontally disposed transparent colored strips to permit the vertical displacement between the patient's respective eyes to be measured when the horizontally disposed transparent colored strips are in the visual axis of the patient, and h. angle measuring means detachably connectable to said instrument frame for measuring the vertical inclination and vergence of each respective eye of the patient.

In an ophthalmic measuring instrument as claimed in claim 1 wherein said angle measuring means detachably connectable to said instrument frame for measuring the vertical inclination and vergence of each respective eye of the patient includes, a. a support member slidably, and adjustably connected to said instrument frame and angularly adjustable relative thereto, b. an elongated support arm detachably connectable to said support member and vertically movable in an arc relative the support member, c. a support platform connected to said elongated support arm remote from the point of connection to said support member, d. a viewing tube adjustably connected to said support platform and horizontally movable into the visual axis of the patient's eye being measured, and e. graduation marks on the said angle measuring means to permit the vertical inclination and vergence angle thereof to be measured.
