ABO Practice Exam
What is the best frame adjustment when the left lens sits Angle left temple in
closer to the patients face than the right lens?
The segment location tolerance in the vertical (segment Pairs Should Match Within 1.0mm Of Specification
height) meridian in a mounted pair of eyeglasses is:
Person that requires no prescription to see at distance is Emmetropic
considered ?
A spectrometer measures the: Light Transmission
The optical center of a lens is: A lens location of zero deviation of the optical axis
Where will the optical center appear in a lensometer when To The Right Of The Target Center
neutralizing a right lens for base in prism?
The vertical difference in power between lenses in the 0.25D sph
following Rx is
OD: +1.00 +0.50 X045
OS: +1.00 +0.50 X090
Astigmatism is corrected by a lens having: cylindrical powers
Given the following prescription, what is the tolerance for +/- 0.125D
the cylinder power?
RX: -11 00 -2.50 X180
The cylinder axis tolerance for a 1.25D cylinder is: 3 degrees
Reflections are reduced on a lens surface by using anti -glare coatings
Which of the following indicates the best distant vision: 20/15
3 multiple choice options
Which wavelengths of light: have been indicated as 350nm--400nm
possible contributor to the onset of cataracts? 3 multiple choice options
If the pupillary distance is measured while the patient is Near PD
focusing on a point 16 inches in front of eyes. The Pd
measured is known as the
, ABO Practice Exam
The type of bridge on a metal frame rests entirely on the Unifit
nose
Iseikonic lenses are used for the correction of: Aniseikonia
Given an Rx of Plano +1.00 X090, corrects which of the simple hyperopic astigmatism
following refractive conditions:
Match the following patient type with the indicated temple Comfort Cable Or Riding Bow
style: small children
Widening the distance between the nose pads results in Lower
the frame sitting
Where do ocular images cross? Optical chiasm
What is the function of the optic chiasm? It helps your brain process visual information and create one image from both eyes.
The optical cross is a graphic representation of a lens that the meridian powers
shows
If your lensometer reads -0.25 with no lens, a lens that -2.75-1.50 x 180
measures -3.00 - 1.50 X180 is actually:
The spherical equivalent of the lens +2.00+2.50 X 090 is +3.25
Children with convergence issues are usually prescribed base in prism
Which of the following would be best to do for a patient steepen the base curve
whose eye lashes are touching the back surfaces of the
lenses?
A plus 0.5 diopter lens decentered 2.0mm creates 0.10Δ
Bicentric Grinding Is commonly associated with vertical imbalance
The focal length of a lens may be altered by: Changing the curvature of one surface
