front 1 Amblyopia | back 1 Loss of vision without any apparent disease of the eye. |
front 2 Anisometropia | back 2 A condition in which the refractive error of one eye significantly differs from that of the other. |
front 3 Antimetropia | back 3 A sub‐classification of anisometropia, is a rare refractive condition in which one eye is myopic and the fellow eye is hyperopic |
front 4 Diplopia | back 4 The seeing of one object as two, due to uneven tracking of the eyes. Commonly known as double vision. |
front 5 Presbyopia | back 5 Gradual lessening of the power of accommodation due to a physiologic change that becomes noticeable about the age of 35. |
front 6 Emmetropia | back 6 When an eye is emmetropic, light rays coming into the eye from a distance come to perfect focus on the retina. When a person has emmetropia in both eyes, the person is described as having ideal vision. |
front 7 Aniseikonia | back 7 A condition in which the image of an object as seen by one eye
differs so much |
front 8 Chromatic Abberation | back 8 Distortion of an optical image produced by the dispersion of light passing through a lens and generally characterized by blurred, multicolored edges. |
front 9 Phoria | back 9 A tendency for the eye to deviate from its visual axis or the normal. |
front 10 Esophoria | back 10 A tendency for one eye to deviate off the visual axis toward the other eye. |
front 11 Exophoria | back 11 A tendency for one eye to deviate off the visual axis away from the other eye. |
front 12 Tropia | back 12 An obvious actual deviation from normal of the axis of the eyes. |
front 13 Esotropia | back 13 Actual deviation of one eye toward the visual axis of the other eye (crossed eyes). |
front 14 Exotropia | back 14 Actual deviation of one eye away from the visual axis of the other eye (wall eyed). |
front 15 Simple Hyperopic Astigmatism | back 15 The refractive condition where one point of focus falls on the retina and the other point of focus falls behind the retina. Example: plano +1.50 x 180. |
front 16 Simple Myopic Astigmatism | back 16 The refractive condition where one point of focus falls on the retina and the other point of focus falls in front of the retina. Example: plano -2.00 x 180 |
front 17 Compound Hyperopic Astigmatism | back 17 The refractive error which results in two points of focus falling behind the retina. Example: +1.00 +2.00 x 090 |
front 18 Compound Myopic Astigmatism | back 18 The refractive error which results in two points of focus falling in front of the retina. Example: -1.00 -2.00 x 090 |
front 19 Mixed Astigmatism | back 19 The refractive condition in which light comes to two points of focus where one point is in front of the retina, and the other is behind the retina. Example: +1.00 -2.00 x 180 |
front 20 Bifocal are used to correct for a condition called: | back 20 Presbyopia |
front 21 An RX with the O.D. minus and the O.S. plus is an obvious case of: | back 21 Antimetropia |
front 22 RX O.D. -4.50 -1.00 x 180, O.S. -2.50 -1.00 x 45, This prescription indicates an obvious case of: | back 22 Anisometropia |
front 23 A patient with a hyperopic prescription always has the following kind of power: | back 23 Plus power |
front 24 An ophthalmic correction for a patient with amblyopia is to focus parallel incident light rays at the: | back 24 Far point of the eye |
front 25 A patient with a myopic prescription always the following kind of power: | back 25 Minus power |
front 26 The condition of vision due to diminished accommodative amplitude which moves the near point further from the eye than is convenient for reading is known as: | back 26 Presbyopia |
front 27 Trifocals are most generally prescribed when the patient has: | back 27 advanced presbyopia |
front 28 Who is the best potential candidate for progressive power lenses? | back 28 A patient with early presbyopia |
