ABO PRACTICE EXAM PART ONE 2024/2025 WITH 100% ACCURATE SOLUTIONS

the ability of the eye to focus objects at varying distances is called - accommodation the Geneva Lens Measure is calibrated for a refractive index of - 1.530 A lens made from 2 convex surfaces - has against motion A lens reads +4.25D in the vertometer. If the ocular curve is -4.00D, what is the front base curve? - +8.25D Which of these front base curves would be suitable for a -300D meniscus lens? - +4.50 A tinted lens will absorb visible light, infrared and ultra violet becasue of - appropriate chemicals added during manufacturing and its density the cornea is continuous with the - sclera which of the following is not ametropia - strabismus the macula is positioned on the - retina which of the following multifocals does not use minus cylinder design? - ultex A an opacity in the lens causing a reduction in vision is called - cataract a simultaneous movement of both eyes in opposite directions is called - vergence in order for the cornea to maintain transparency, it must have - a liquid environmentimbalance of aqueous humor in the anterior chamber results in - glaucoma binocular vision allows an individual to - have fusion, have a perception of depth, and have an enlarged field of view the ability of the eye to turn out is called - abduction the color sensors of the eye are called - cones a frame that measures 54 prism 20 with an E.D. or 57mm is selected by a person for a single vision lenses. if each lens must be decentered 5mm in, then the minimum blank size needed to complete this job is - 68mm what lens power in the 90th meridian for this lens prescription: +3.00 +1.00 x 180 - +4.00 if three identically shaped meniscus convex lenses are made, one from each of these ophthalmic materials: ophthalmic crown, polycarbonate and CR-39, which will read the strongest plus power in the lensometer? - polycarbonate a patient refractd at 8mm is prescribed a +10.00 lens. The fitted vertex is 13mm. The recomputed (compesated) lens power is - +9.50 the wavelength of the infrared waves in the electromagnetic spectrum are - longer than visible red light waves base curve can be defined as - the curve used as a basis for surface curves the difference between distance and segment optical centers is called - inset
