ABO PRACTICE TEST EXAM Q&A 2023/2024 Corpuscular - CORRECT ANSWER-the theory which explains light as a stream of invisible bundles of energy Photons - CORRECT ANSWER-the visible bundles of energy Electromagnetic Theory - CORRECT ANSWER-The theory which explains light as moving in a series of wave pulsations. 186,000 miles per second - CORRECT ANSWER-the speed of light in air ray - CORRECT ANSWER-a point of light pulsating in a straight line all colors - CORRECT ANSWER-the colors that visible or white light are composed of base - CORRECT ANSWER-a prism will bend light towards its one meter - CORRECT ANSWER-one diopter prism will deviate a ray of light one centimeter in a distance of apex - CORRECT ANSWER-the image being viewed through prism will always be displaced towards its refraction - CORRECT ANSWER-the bending of light as it passed from a medium of lesser density to a medium of greater density is known as refractive index - CORRECT ANSWER-the speed of light in air divided by the speed of light in a material optical center - CORRECT ANSWER-the single point on an optical lens through which light may pass without being deviated converging/against motion - CORRECT ANSWER-plus lenses can be characterized by these two attributes diverging/with motion - CORRECT ANSWER-minus lenses can be characterized by these two attributes minus spheres - CORRECT ANSWER-simple myopia or nearsightedness can be corrected with these type of lenses plus spheres - CORRECT ANSWER-simple hyperopia or farsightedness can be corrected with these type of lenses cylinder lenses - CORRECT ANSWER-an eye which requires a different correction in different meridians can be corrected with these type of lenses 530 mm - CORRECT ANSWER-the radius of curvature of a one diopter lens +1.75 - CORRECT ANSWER-The total power of a lens with a +6.00 diopter front surface and a -4.25 diopter back surface lens. two plus surfaces - CORRECT ANSWER-a biconvex lens 1 meter - CORRECT ANSWER-the focal length of a one diopter lens +3.00 +2.00 x 005 - CORRECT ANSWER-the correction transposition of the following rx: +5.00 -2.00 x 095 out - CORRECT ANSWER-the pupillary distance ground too wide for a plus Rx will result with this type of prism base out - CORRECT ANSWER-the pupillary distance ground too narrow for a minus rx will result with this type of prism base base in and base in - CORRECT ANSWER-this combination of prism is not a canceling situation base up and base up - CORRECT ANSWER-this combination of prism is not a compounding situation radius of curvature - CORRECT ANSWER-not an element of the Prentice Rule formula 1.5 diopters - CORRECT ANSWER-the resulting total prismatic effect of a pair of 3 diopter spheres that is 5mm too wide plano - CORRECT ANSWER-the total power of the following rx at an 180 axis: +2.00 -2.00 x 090 +/- 2 degrees - CORRECT ANSWER-the tolerance for a cylinder of 1.62 diopters or greater 2/3 diopters - CORRECT ANSWER-the recommended limit for horizontal prism tint - CORRECT ANSWER-this will not affect lens thickness effective diameter - CORRECT ANSWER-this is twice as long as the given radius of any shape saggital value or sag - CORRECT ANSWER-an indictor of lens thickness closet distance between lenses - CORRECT ANSWER-DBL "A" Box - CORRECT ANSWER-measurement referring to the horizontal straight line between the farthest nasal and the farthest temporal point of a lens reads base curves - CORRECT ANSWER-not a function of the lensometer reticle - CORRECT ANSWER-the concentric circle configuration within the scope of the lensometer front side - CORRECT ANSWER-the bifocal add must be read with this side on the lens against the lens stop binocular - CORRECT ANSWER-the pd measurement which indicated the distance from the center of the pupil to the center of pupil monocular - CORRECT ANSWER-this type of PD best compensates for facial asymmetry upper right - CORRECT ANSWER-You are looking at a right lens in the lensometer. The Rx call for 1 BU and 2 BI. You find the optical center in this quadrant. -7.50 - CORRECT ANSWER-A lens has a front curve of +6.50. What back curve would yield a corrective power of -1.00? -6.50;-7.50 - CORRECT ANSWER-If a lens has a front curve of +4.50 which back curves would be required to create a lens with a power of -2.00 -1.00 x 180? 0.1766m - CORRECT ANSWER-A +3.00 diopter lens has this radius of curvature. violet - CORRECT ANSWER-The component of visible light has the shortest wavelength. apex to apex - CORRECT ANSWER-Minus lenses are though as two prisms or as a series as these. compound hyperopic astigmatism - CORRECT ANSWER-The following rx corrects this type of visual condition. +2.00 -1.50 x 180 OU
