Optometry

1. 1. Which vision correction method causes the fewest complaints about glare?

• Spectacles

• LASIK

• Contact lenses

• Orthokeratology

3. 2. Not all patients can adapt to prescribed glasses. According to some research, the average rate of spectacle non-tolerance (cases where patients return with complaints to optical practices) was found to be:

• 0.9%

• 2.3%

• 4.1%

• 5%

3. In a study investigating the effects of low-addition convex lenses on reading rate and subjective preference among pre-presbyopes (aged 20-40 years) with digital eye strain symptoms.

Participants tested four lenses: +0.50D, +0.75D, +1.25D, and a plano lens during near work tasks. According to the study findings, which lens addition was the least preferred by participants?

• 0.00D

• +0.50 D

• +0.75 D

• +1.25 D

4. 4. The most common reason patients could not adapt to a new prescription was cylinder changes (36%). What were the second, third, and fourth most common reasons:

• under-plused; over-minused; add too high

• under-plused; under-minused; add too low

• Over-plused; under-minused; add too low

• Over-plused; under-minused; add too high

5. Which parameter should be additionally specified in a spectacle prescription in the UK, when the lens power is ±5.00 D or greater, besides lens power and pupillary distance?

• Base curve

• Refractive index of lens

• Back vertex distance

• Pantoscopic tilt

6. Which assumption about an automatic lensmeter is correct?

• It is not possible to find the optical centre in a prismatic lens using an automatic lensmeter

• It is not possible to assess the add power of progressive lenses using an automatic lensmeter

• It is not possible to locate the optical centre of a spherical lens using an automatic lensmeter

• It is possible to assess the add power, to locate the optical centre in both prismatic and spherical lenses using an automatic lensmeter

7. Which one is the occupational progressive lens (office lens)?

All lenses are for the right eye.

• 1.

• 2.

• 3.

• 4.

8. What visual complaints might the client have in this case if they have myopia?

• Blurred distance vision

• Blurred near vision

• Vertical diplopia (vertical double vision)

• In this case, no visual complaints are expected

9. Which lens parameter is determined using this point of the progressive lens?

• This is a geometric point of the lens and has no specific application

• At this point, the lens power for intermediate viewing distance is determined

• At this point, the prismatic power of the lens is measured

• This point indicates the position of the pupil

10. For progressive lenses, prism measurements are performed at the prism reference point, and the following measurements have been obtained (see figure) with automatic focimeter. What prismatic correction is prescribed?

• OD 2.00∆ BI

• OD 4.24∆ 45°

• OD 4.24∆ 135°

• OS 2.00 BU
