ABO Practice Test correctly answered graded A+ 2023Corpuscular - 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
