Comprehensive Prep
1. Which of the following are symptoms of anisometropia?

Headaches

Eyestrain

Reduced depth perception

All of the above

2. In a scenario where a patient expresses confusion about their prescription,
how would you utilize the EBAR framework to address their concerns?

Assess their vision first, then explain the prescription without asking
questions.

Elicit their concerns, assess their understanding, provide
clarification, and respond to their questions.

Engage them in a discussion about lens types, then provide a
prescription.

Provide a detailed explanation of the anatomy of the eye before
addressing their concerns.

3. A patient reports difficulty reading small print but can see distant objects
clearly. Which refractive error might they be experiencing, and what
corrective measure would you recommend?

Hyperopia; recommend reading glasses or multifocal lenses.

Myopia; recommend contact lenses for distance vision.

Presbyopia; recommend eye exercises to strengthen vision.

Astigmatism; recommend prism glasses to correct vision.

,4. You receive a pair of glasses back from your fabrication lab that measures
-1.25 -0.25 x 030. The original order was -1.25 -0.25 x 018. Before contacting
your patient to let them know their glasses are ready for pick-up you check
ANSI standards to see if this is within tolerance. According to ANSI standards,
what is the tolerance for error in cylinder axis for this prescription?

Axis may deviate up to 14 degrees

Axis may deviate up to 3 degrees

Axis may deviate up to 7 degrees

Axis may deviate up to 5 degrees

Axis may deviate up to 18 degrees

5. What term indicates that a drug will be distributed throughout the entire
body?

pulmonary

topical

subcutaneous

systemic

6. Irregular astigmatism means that

the astigmatism changes in an irregular way with age.

the astigmatism causes the 1st PS image to appear irregular.

the principal meridians are not perpendicular.

the residual astigmatism is not ATR.

there is an optical distortion due to irregular eye movements.

,7. If a patient reports discomfort and blurred vision after being fitted with a
contact lens that is steeper than their 'K' measurement, what should the
optometrist do?

Prescribe eye drops to alleviate discomfort.

Instruct the patient to wear the lenses longer.

Re-evaluate the lens fit and consider a flatter lens design.

Advise the patient to switch to glasses instead.

8. If a patient expresses confusion about their lens options during a
consultation, how should effective communication be applied?

Avoid discussing the options to prevent confusion.

Clarify the options and address their concerns with patience.

Suggest the most expensive option immediately.

Redirect the conversation to another topic.

9. Simple hyperopic astigmatism

focal point is normal

focal point fall below retina

The refractive condition where one point of focus falls on the retina
and the other point of focus falls behind the retina.

focal point falls in front of retina

10. Which term refers to the process of providing information and guidance to
patients in optometry?

negotiating

informing

, persuading

consultative dispensing

11. What is the term for the distortion of image shape caused by high minus
lenses?

Chromatic aberration

Barrel distortion

Spherical aberration

Pincushion distortion

12. A patient presents with difficulty seeing both near and far objects clearly.
Upon examination, the optometrist diagnoses them with simple hyperopic
astigmatism. What type of lenses would be most appropriate for this patient?

Convex lenses

Concave lenses

Cylindrical lenses

Bifocal lenses

13. Drug distribution can be defined as

the process by which a drug is eliminated from the body through the
kidneys or interesting

the metabolism of drugs (especially in the liver)

a simple passive diffusion of a drug molecule from an area of high
concentration to an area of lower concentration

the process by which a drug is carried from its site of absorption to
its site of action
