CE Test Questions
Vertically Challenged - Part 1

Exam Questions
1. Prismatic effect can be calculated using:

    D. Both b & c
2. Anisometropia:

    A. Is a refractive condition that always requires prism to correct it
    B. Is when one eye is plus and one eye is minus
    C. Is defined as unequal refractive errors in the two eyes
    D. A term used for “Lazy Eye”
3. When looking through a position below the OC, a “plus” lens will:

    A. Induce a BU prismatic effect
    B. Cause the image to appear to shift downwards
    C. Induce a BD prismatic effect
    D. a & b
4. Vertical Imbalance:

    A. Has no effect on stereopsis at the NP
    B. Is only a problem when looking at a distant object further than 20 feet away
    C. Is most commonly experienced by multifocal wearers with good acuities in both eyes
    D. Can be easily remedied by using AR coated lenses
5. A single vision lens is a good way to reduce vertical imbalance at the NP because:

    A. It increases multiple pair sales
    B. It avoids having to measure seg heights
    C. The patient has the option of looking directly through the OC by sub-consciously repositioning their head
    D. It makes the lenses thinner
6. When designing single vision readers:

    A. It is recommended to select a larger frame so the patient has a greater field of vision
    B. Raise the position of the OC by 5mm above the vertical geometric center of the lens
    C. Select a frame with a “B” measurement that allows for it to sit lower on the bridge
    D. a & b
7. If the prescribed add power for a WD of 16” is +2.00, the add power needed for 40” is:

    A. + 0.50
    B. +1.00
    C. +1.50
    D. +0.75
8. If filling an outside Rx with an add power of +3.50 and the patient requests glasses for a WD of 32”:

    A. It is safe to assume the +3.50 add is for 16”, so simply order the glasses using a +1.75 add power
    B. It is recommended to call the prescribing doctor to verify the WD for which the add was determined
    C. Inform the patient that because the add power is greater than +2.50 they will need to return to the prescribing doctor to get a prescription for the WD they need
    D. None of the above
9. A monocular distance PD of 34 is measured. If making a pair of single vision glasses for a WD of 32” the PD should be:

    A. Reduced by a factor of 1mm
    B. Increased by a factor of 1mm
    C. Reduced by a factor of 2mm
    D. Left unchanged
10. Dissimilar Segs:

    A. Involves using the difference in magnification between the different lens styles to offset vertical imbalance
    B. Involves using the prismatic effect induced by the bifocal segment to offset vertical imbalance induced by the distance lens at the NP
    C. Makes the glasses look more trendy
    D. Are a more expensive option than any other to resolve vertical imbalance and should never be considered
11. When using dissimilar segs:

    A. The bifocal segment behaves as its own miniature lens and can offset vertical imbalance
    B. The bifocal segment never has any effect on vertical imbalance
    C. If the same power & style of bifocal is used for each eye the imbalance induced by the segs can be disregarded
    D. a & c
12. The OCs of all bifocal segments:

    A. Are positioned at the same position relative to the top of the seg
    B. Are positioned at different points within the seg depending on the bifocal style
    C. Bifocals do not have OCs
    D. Unimportant when it comes to imbalance calculations
13. The direction of the vertically induced prism is:

    A. Always BD
    B. Dependent on lens power
    C. Dependent on whether looking through a point in the lens above, or below the OC
    D. b & c
14. When using dissimilar segs:

    A. The bifocal style with the highest OC should be used on the least minus lens
    B. The bifocal style with the highest OC should be used on the most minus lens
    C. The bifocal style with the lowest OC should be used on the least plus lens
    D. b & c
15. Vertical Imbalance:

    A. Is mostly a problem for multifocal wearers
    B. Is mostly a problem for patients with good visual acuity in both eyes
    C. Is mostly a problem for patients with an imbalance greater than 0.5 prism diopters
    D. a and b
16. With an outside Rx where vertical imbalance may be an issue, the author recommends:

    A. Taking advantage of the opportunity to charge more as needed
    B. Taking the patient in the exam room to perform a refraction to determine best corrected acuities
    C. Asking the patient what their best corrected acuities are and if they are bothered by vertical imbalance caused by induced prism at the NP
    D. Placing a call to the prescribing doctor to investigate further
17. Pantoscopic Tilt:

    A. Has no effect on the position of the OC
    B. Refers to the amount of wrap a frame has applied to it
    C. Is usually 5 to 15 degrees
    D. b and c
18. Light rays entering a lens at a point other than the OC will:

    A. Pass through without deviation
    B. Will be deviated by an amount affected by the refractive index of the material
    C. Will be deviated by an amount affected by the angle the ray hits the surface
    D. b and c
19. With dissimilar segs:

    A. A FT style should always be used on the most plus lens
    B. The bifocal style with the highest OC should always be used on the most plus lens in the vertical meridian
    C. The bifocal style with the highest OC should always be used on the most minus lens in the vertical meridian
    D. The bifocal style with the highest OC should always be used on the most minus lens in the horizontal meridian
20. A patient viewing through a SV +6.00 sphere lens, 15mm below the OC will experience:

    A. No induced prism because the lens is single vision
    B. 9 diopters BU
    C. 9 diopters BD
    D. 0.9 diopters BU
